The following is a long treatise and analysis of the Tectonic Strain
Theory. The TST is widely purported to explain UFOs, ghosts, psychic
events, religious ecstacy, spontaneous combustion and pretty well
anything else you might name. Literally hundreds of papers have
appeared in scientific journals, assuming its real existence and
reality. However, there have been very few critical works about the
TST, and when such works have surfaced, the critics have been dismissed
with commentary or discussion about how complicated the issue is and
why it cannot be quantified easily. In short, its proponents appear to
invoke almost identical reasons as defendants of the reality of psychic
phenomena, and this in itself raises concern among some researchers.

This paper was originally written as a geophysical thesis in 1983, and
although more than 10 years old, is still relevant as a critical look
at the TST which is still being invoked as a scientific explanation of
purportedly paranormal phenomena.

The paper has recently been converted into ASCII by David Thacker of
AUFOSG and provided online by Chris Rutkowski.

         Abstract

         A new hypothesis, explaining unidentified luminosities,
         has been proposed which has received wide attention and gen-
         eral acceptance. It incorporates both geophysical and physi-
         ological mechanisms in an attempt to explain the wide vari-
         ety of characteristics of the phenomenon. This study
         examines the feasibility of the theory from an objective
         standpoint, and tests the tenability of the interrelations
         of its interdisciplinary mechanisms.

                                  INTRODUCTION

         Since their entry into the scientific and lay literature
         in the late 1940's, few topics have caused such controversy
         as that of UFOs (Unidentified Flying Objects). While tradi-
         tionally ignored or lightly treated by the scientific commu-
         nity, the persistence of the phenomenon over 30 years has
         led some researchers to consider them more seriously (Ja-
         cobs, 1976).

         It is recognized that the phenomenon has drawn to it a
         large contingent of unscientific and unprofessional "believ-
         ers", many of whom fail to objectively view UFOs without
         bias. This is not necessarily surprising, given science's
         stance on the matter, but a Catch-22 situation has resulted.
         Because the subject is not "reputable", few scientists have
         spent adequate time considering the problem in detail. This
         has left the study of the phenomenon to laymen, and often to
         cult believers. This has kept the "reputation" of UFOs at a
         low level, and the circle has been completed.

         But probably because of the relatively long history of
         UFO reports, some scientists have proposed theories to ex-
         plain them. Some scientists advocate the ETH (Extraterres-

                                     - 1 -

         trial Hypothesis), which states the most popular UFO expla-
         nation: that they could be spacecraft from extraterrestrial
         civilizations. Unfortunately, though most astronomers be-
         lieve that extraterrestrial civilizations exist, there is no
         scientifically-acceptable evidence that such civilizations
         have in fact contacted mankind (Hendry, 1979).

         Other explanations proposed for UFOs include: "lost" ter-
         restrial civilizations; "secret" terrestrial devices; spir-
         itual entities; "natural" phenomena; and mass hallucinations
         (Jacobs, 1976). None have withstood scrutiny as of this
         date.

         It should be noted at the outset that one of the few
         facts known about UFOs is that about 90 to 95 percent of all
         UFO reports are misidentifications of conventional or natu-
         ral phenomena (Hendry, 1979). It is the remaining, signifi-
         cant percent that is regarded when discussing UFOs - the
         "real unknowns". It is generally felt by skeptics that this
         percentage of UFOs can be explained if strong effort is
         made, or it can never be explained other than in terms of a
         "background noise" of spurious data. Proponents of the UFO
         phenomenon as a much more complicated mystery disagree with
         the skeptics. They argue that the remaining percentage of
         reports is unexplainable even after attempts to explain them
         have been made. This disagreement is the prime focus of the
         UFO controversy.

                                     - 2 -

         Natural phenomena have been suggested as an explanation
         for UFOs many times (e.g. Klass, 1966). The main drawback
         to natural phenomena theories is that UFO reports offer such
         a wide variety of characteristics that natural phenomena
         fall short of explaining all UFO traits. Recently, however,
         a theory has been proposed which seems capable of explaining
         many UFO characteristics based on a mixture of mechanisms
         and processes. This theory, called the TST (Tectonic Strain
         Theory), begins with the suggestion that strain fields with-
         in the Earth's crust can produce an electromagnetic dis-
         charge that may manifest itself in one of two basic ways.
         One way is by the electric discharge becoming visible as a
         moving body of light. The other way is by the discharge af-
         fecting the human brain so that the observer will "believe"
         he or she is viewing a moving body of light. Both scenarios
         are consistent with the theory, and are used to explain the
         reported appearances of UFOs.

         So far, only statistical evidence has been presented in
         support of this theory. This has been in the form of covari-
         ation of the number of reported UFOs in an area and the lev-
         el of seismic activity in that area. Whether this is a
         "real" relationship or an artifact is not clear at the pres-
         ent time.

                      THE TECTONIC STRAIN THEORY AND UFOS

         The Tectonic Strain Theory (hereafter referred to as the
         TST) is a relatively new explanation for the reported ap-
         pearance of inexplicable luminosities, sometimes
         UFOs. Papers dealing with certain aspects of the theory
         have been published in several journals, covering various
         disciplines (Persinger, 1975, 1976, 1979a, 1979b, 1980a,
         1981, 1982, 1983a, 1983b, 1983c, 1983d, 1983e, unpubl, un-
         pub2). The proposed mechanism is interdisciplinary in na-
         ture, and carries with it some necessary qualifications to
         enable it to cope with a poorly-understood phenomena in
         terms of better-known phenomena. The theory is best ex-
         plained by its major proponent, Michael A. Persinger:

                 "Essentially,...normal geophysical processes applied
                 in unusual space-time configurations are responsible
                 for electromagnetic phenomena that have direct physi-
                 cal and biological consequences. These processes in-
                 volve normal alterations in tectonic (structural)
                 stresses within the Earth's crust and are mediated by

                                     - 4 -

                 piezoelectric-like effects. The primary natural analog
                 of this putative phenomena would be earthquake light-
                 ning...Whereas earthquake-related luminosities appear
                 contingent upon large releases of structural strain
                 (seismic activities), the luminosities and electromag-
                 netic correlates of alleged close encounters with UFOs
                 are associated with HIGHLY LOCALIZED, less intense
                 changes in crustal structures not necessarily involv-
                 ing major seismic activity." (Persinger, 1979b)

                 (author's emphasis)

         The TST draws upon several processes for its mechanism,
         and it is best to examine each of them in some detail. The
         physical processes are linked implicitly by logical argu-
         ments, although the basis for these arguments needs careful
         examination. The major steps involved are:

                 1) Strain is produced in the Earth's crust.
                 2) Strain produces an electromagnetic discharge.
                 3A) The electromagnetic discharge produces a luminosity.
                 4A) The luminosity is observed as a UFO.

         Alternatively, steps 3A and 4A may be replaced by:

                 38) The electromagnetic discharge affects human per-
                 eption.
                 4B) A person believes that he/she has seen a UFO.

                                     - 5 -

         In order to understand the TST, each of these steps will be
         considered in systematic sequence, in effect testing the
         links in the chain.


         2.1 CRUSTAL STRAIN

         Through various processes, strain can be built up in the
         Earth's crust. These include tectonic activity, tidal action
         and human activity.

         Strain is described in terms of dilational and distor-
         tional strain tensors, as it is a vector in three dimensions
         (Bath, 1973; Kasahara, 1981; Richter, 1958). The strain ten-
         sor is defined by the equation:

[NOTE: In this ASCII version, CX represents the Greek symbol alpha,
^2 means squared, _u represents mu, _[ is the integration symbol,
pi is the pi constant, _B is the symbol for beta.]

                     E(i,j) = e(i,j) - (1/3)e(k,k)CX(i,j)

         and similarly, the stress tensor is:

                     P(i,j) = p(i,j) - (1/3)p(k,k)CX(i,j)

         where the arrays e(i,j) and p(i,j) each consist of nine com-
         ponent vectors which define the stress and strain across any
         small plane area containing the point in question. The re-
         lease of tectonic elastic strain energy is the cause of ma-
         jor earthquakes. This energy can be expressed in a function
         and form such that:

                     U = _[_[_[_uE^2(i,j) dV

                                     - 6 -

         where _u is the rigidity modulus (the measurement of the re-
         sistance of an elastic solid to shearing deformation) and U
         is the distortional strain energy, taken through the volume
         (Bullen, 1963).

         The stress tensor is defined as:

                     P(i,j) = 2_uE(i,j)

         Now, we can also define the stress tensor in terms of the
         Mises function:

                     P^2(i,j) = (CXS)^2

         where S is the value P would have if the material was near
         the breaking point. CX is a constant that has a value between
         0 and 1, and sometimes assigned a value of (sqrt(3))^-1

         We can then find E in terms of S such that:

                     E(i,j) = (CXS)/(2_u)

         we can substitute into our equation for U and find:

                     4_uU = CX^2S^2Q

         where Q is the volume of the strained region near breaking
         point.

         The total energy released in an earthquake can be roughly
         calculated by a modified Gutenberg-Richter formula:

                     log E = 11.8 + 1.5 M

                                     - 7 -

         The total energy released in an earthquake of magnitude 8.9
         (the greatest on record) is thus about 5 x 10^24 ergs (Bul-
         len, 1955; Kasahara, 1981).

         The strain energy, U, will be some fraction of the total
         energy, E, since there are other forms of energy release
         such as the dilational strain energy, heat and sound, etc.
         Thus, we can replace U by qE, where q lies between 0 and 1.
         Our new equation is then:

                     z_uE = S^2Q

         where z = 4q (= approximately 2).

         Experimental results have provided estimates for _u and S:

                0.4 x 10^12 dyne cm^-2 < _u < 1.5 x 10^12 dyne cm^-2

                S is approximately equal to 10^9 dyne cm^-2

         We can then use our equation to calculate Q. The volume
         of the region near breaking point prior to an earthquake is
         therefore about 10^19 cm^3, with a radius of about 20 to 50 km
         in extreme cases (Bullen, 1953, 1955).

         But this radius is only for the overloaded crustal re-
         gion. The actual volume of rock in which significant strain
         exists is obviously much greater than this, but can not be
         known precisely.

                                     - 8 -

         However, reasonable estimates of the size of the total
         strained region can be made by comparing the distances be-
         tween earthquake epicentres and precursory effects, indi-
         rectly using the magnitudes and energies involved (Brown and
         Reilinger, 1983). It is extremely difficult to judge the ac-
         tual extent of precursory effects, since they will intui-
         tively vary in type, depth and strength for each earthquake.
         The determination of the size of the strained region will be
         discussed further, at a later point in this paper.


         2.2 STRAIN-PRODUCED RADIATION

         There are many types of reported Earthquake precursors on
         record, including ground deformation, change in the levels
         and chemistry of well-water and the unusual behavior of ani-
         mals (Buskirk et al., 1981; Rikitake, 1976; Wyss, 1983). A
         form of precursor that has received relatively little atten-
         tion is that of the emission of electromagnetic radiation.
         Although many such reports are spurious or represent other
         natural or man-made causes, a significant number are well-
         documented, and the existence of earthquake-related EM ef-
         fects must be seriously assessed.

                                     - 9 -

         On 31 March, 1980, anomalous EM emissions were recorded
         thirty minutes before a deep-focus (depth = 480 km) magni-
         tude 7 earthquake 250 km from an observatory near Tokyo
         (Gokhberg et al., 1982). These emissions were widely-sepa-
         rated at 10 Hz and 81 kHz. Other similar emissions were re-
         corded for a magnitude 7.4 earthquake in Iran, 1200 km from
         the epicentre, at 27 kHz and 1.63 MHz. Other examples of
         such emissions have also been reported (Gokhberg et al.,
         1980; Sadovskiy et al., 1979).

         It has been known for some time that the strain loading
         of rocks and minerals produces electromagnetic emission. The
         strength of the emission varies with the different types of
         substances; the strongest emission arises from quartz and
         other minerals with a high crystal lattice energy, while
         rocks such as sandstone have a very low ability to produce
         emission under strain. It has been reported that there is a
         shift to high frequency with an increase in grain size. The
         actual mechanism for the production of the emission is not
         definitely known, although several theories have been pro-
         posed (Lockner et al., 1983; Mizutani et al., 1976).

         It has been shown that a rapid drop in the piezoelectric
         field when stress is released (i.e. when fracturing occurs)
         can produce EM emission. Experiments have shown that the
         peak frequency for such a piezoelectric pulse is at about
         1.7 kHz, and that the energy release from the fracture of a

                                     - 10 -

         small rock specimen with a volume of 50^3 cm is about 10^-18
         J. However, there is some doubt that piezoelectricity can
         produce earthquake lights because of its rapid decay and the
         possibility of its self-cancelling nature (Finkelstein et
         al., 1973; King, 1983).

         An alternate theory for EM emission during fracturing is
         that of RF (radio frequency) emission caused by a charge
         buildup across microcracks. During strain processes, there
         will be discharges between walls of the microcracks which
         can give not only RF emission, but also IR (infrared) and
         visible light as well. The energy released by these small
         cracks has an average spectral range of between 1 and 10^3
         MHz (Perel'man and Khatiashvili, 1981).

         The most plausible proposed mechanism involves the propa-
         gation of an elastic wave within rock, following fracture.
         Demin et al., (1981) have speculated that the wave would in-
         duce the growth of microcracks, and, in the case of semicon-
         ducting and piezoelectric minerals, the cracking would pro-
         duce electrical discharges. But the piezoelectric field
         might also create transistors within the rock, using as bar-
         riers the layers of semiconducting minerals occurring natu-
         rally in the ore. These transistors could be coupled into
         circuits, and an EM emission caused by the formation of mi-
         crocracks could be amplified, in theory, by these piezoelec-
         tric and semiconducting minerals. It is immediately obvious

                                     - 11 -

         that in this mechanism the frequency of the amplified EM
         wave would be dependent on several variables, especially the
         composition of the rock. This frequency could, depending on
         these variables, be represented at many points in the EM
         spectrum, including radio, infrared, visible and x-ray wav-
         elengths. As a point of note, it has been shown that ultra-
         sonic pulses can also be generated by rock fractures (Demin
         et al., 1981).


         2.3 LUMINOSITY FROM ELECTROMAGNETIC DISCHARGE

         As was mentioned in section 3.2, EM emission by rock
         fracture will probably also include visible wavelengths. The
         actual size of the luminosities thus produced is difficult
         to ascertain. While luminescence has been reported in the
         literature, this has only been in the form of "comet tails"
         and sporadic outbursts detected on photographic film in
         close proximity to the rock outcrop undergoing fracture.
         However, it has been claimed that small, luminous bodies
         have been detected on the film of the fracturing of a core
         sample in the laboratory (Brady, private communication).{1}

         __________
         {1} A description of the experimental conditions under which
         the luminosities were observed is given by Brady et al(unpub).

         These bodies have the reported appearance of sparks caused
         by the impact of rocks upon one another, but are believed to
         be fracture- and not impact-related. It has been suggested
         that if the processes which produce EM emission during rock
         failure are scale invariant, then in nature, luminosities
         will be produced by the strain and fracture of large or bod-
         ies beneath the Earth's surface (Brady et al., (unpub)).
         These luminosities produced outside the laboratory will, it
         is thought, be much larger than those observed in the labo-
         ratory, perhaps reaching 1 m or more on diameter.


         2.4 UFOS AS FRACTURE-RELATED LUMINOSITIES

         If it is indeed possible that large luminosities can be
         produced in nature by crustal stress, then it would seem
         likely that they would have been observed and reported. Many
         reports of seemingly inexplicable lights in the sky have
         been made throughout history, many given the name "UFO" by
         default (Jacobs, 1976). But there do exist rare, natural
         phenomena that appear as lights in the night sky. These in-

                                     - 13 -

         clude ball lightning and earthquake lights, both of which
         are still not fully understood by scientists, but progress
         is being made in unravelling their mysteries (e.g. Charman,
         1979).

         In general, earthquake lights are luminous hemispheres,
         20 to 200 m in diameter, with a duration following an earth-
         quake of 10 seconds to 2 minutes. In addition, radio inter-
         ference is reported to occur after the luminescence, strong-
         est at about 15 kHz, which is an order of magnitude from the
         peak emission for strain release under laboratory conditions
         (Derr, 1973,1977; Finkelstein and Powell, 1970).

         It has been suggested that the release of stress before
         an earthquake could generate large electric potentials, cre-
         ating fields of 10^5 V/m (Demin et al., 1981). If rocks can
         possess a high enough resistivity (about 10^9 ohm - m), then
         earthquake lights might be explainable in this manner (Gokh-
         berg et al., 1980).

         Ball lightning has been reported infrequently, but enough
         cases are on record that some characteristics have been de-
         termined (Barry, 1968). It is spherical, with a diameter of
         about 30 cm, and may have a contained energy of 10^3 to 10^7 J
         (with an average of about 10^5 J) and an energy density be-
         tween 10^2 and 10^3 J cm^-3.

         2.5 ELECTROMAGNETIC EFFECTS ON THE HUMAN SYSTEM

         Rather than creating a physical luminosity through the
         production of visible photons, an alternate method to pro-
         duce a UFO in the TST is the direct effect of EM radiation
         upon the human brain.

         It has long been understood that both electric and mag-
         netic fields affect physiological systems in various ways.
         Effects range from dizziness and irritation in weak fields
         to severe disruptive effects such as induced epilepsy in
         strong fields. Basically, it appears that the electrochemi-
         cal responses within the body are interfered with by exter-
         nal fields, causing the confusion of signals received and
         originating from the brain. Experimental tests have shown
         that headaches are frequently reported by individuals ex-
         posed to electric fields of 15-25 kV/m for extended periods
         of time (Sheppard and Eisenbud, 1977). As well, fatigue and
         sleepiness are also reported to be symptoms of prolonged ex-
         posure to electric fields, although other studies fail to
         support this, possibly due to differing experimental condi-
         tions. Medical examinations of individuals exposed to elec-
         tric fields have found changes in blood composition and car-
         diovascular function (Persinger, 1973).

         Since the human body behaves as a conductor, external
         electric fields will be internally attenuated except in the
         upper-layers of the skin.

                                     - 15 -

         The perception of electric and magnetic fields by human
         beings has been a topic of interest for many years. Elec-
         tric fields of 50-60 Hz, of >10 kV/m can be consciously de-
         tected by humans, probably by the erection of body hairs.
         Weaker fields of <5 V/m are claimed to produce behavioral
         effects, although the physiological mechanism for this is
         not fully understood (Sheppard and Eisenbud, 1977).

         The problem of magnetic field exposure is not an easy
         one, as few studies have been conducted on this topic. So
         far, the actual effects are not known, although the strength
         at which magnetic fields are thought capable of influencing
         biological functions may be as low as 1 Gauss. Magnetic
         fields are not attenuated within the body, and also will
         tend to induce currents within the body, so their effects
         might be construed as being of more significance than elec-
         tric fields. Experiments have shown that magnetic fields may
         be perceived as low as 10 Gauss in strength (Becker, 1969). It
         has even been proposed that the detection of weak magnetic
         gradients can explain the "art" of dowsing in humans (Ro-
         card, 1964).

         Actual changes in the electrical activity of the brains
         of animals have been found using low-frequency electric
         fields of 100 kV/m. Biological cycles (circadian rhythms)
         have also been reported as being affected by exposure to
         electric fields, and there is evidence of effects on blood

                                     - 16 -

         cell counts in humans following exposure.{2} In all probabili-
         ty, the mechanism for the changes is due to the production of
         stress from the influence of electric and magnetic fields
         upon the human metabolism, encouraging an increase in the
         production of steroids within biological systems. There is
         also some evidence that electric fields may operate directly
         upon the central nervous system, interfering with the normal
         transmission of information to and from the brain (Beal,
         1974).

         Interestingly, there are phenomena known as magnetic
         phosphenes which may be relevant to the subject of UFOs. Un-
         der the influence of an alternating magnetic field with a
         strength >100 Gauss and at frequencies between 10 and 100
         Hz, an individual will observe flashes of light. The peak
         frequency for this effect is at about 20 Hz. Whether this
         has any bearing on the reporting of UFOs is not known (Shep-
         pard and Eisenbud, 1977).

         __________
         {2} Because of the potential danger in exposure to EM radia-
         tion, limits were recently proposed for the maximum recom-
         mended level of human irradiation (Cahill, 1983).

         2.6 TEMPORAL LOBE EXPERIENCES

         Under extreme conditions, it has been speculated that at
         high voltages, individuals might experience rather severe
         alterations in normal brain functions (Persinger, 1983c).
         "Dreamy conditions" and temporary paralysis might be experi-
         enced. Other suggested sensations are out-of-the-body expe-
         riences (OOBEs), religious "awakenings" and feelings of
         "cosmic significance", since these emotions can be produced
         by stimulating the limbic structures of the brain (including
         the hippocampus) with electric currents. Such stimulation
         apparently may induce "false" memories of dreamed events,
         making a person "believe" he or she has experienced some-
         thing which has not occurred. These "artificial hallucina-
         tions" would seem "real" to the individual thus influenced.
         In this way, the "bizarre" aspects of UFO experiences such
         as seeing an alien entity, conversing with it, etc., might
         be explained in terms of an interference in brain functions
         (Persinger, 1983e).

         The stimulation of the temporal lobe is perhaps the most
         interesting of all the effects noted. This stimulation could
         produce disorientation and epileptic-like experiences that
         might include actual seizures and loss of consciousness.
         Upon recovery, the individual might well have amnesia re-
         garding certain parts of his or her experience, all due to
         electrical interference within the brain (Persinger, 1979b).

                                     - 18 -

         The suggestion is that the behavior of the individuals is
         not unusual in any way. Rather, it is the interpretation of
         the experiences which is unusual, and thus, the UFO phenom-
         enon can be reduced to a poor interpretation of the experi-
         ences of individuals who have actually been in contact with
         geophysical electromagnetic emissions. However, the reasons
         for the consistent description of such experiences in terms
         of UFOs are not elaborated upon in the TST.

         The TST includes some consideration of the separation be-
         tween the observer and the geophysical luminosity. At a dis-
         tance, only the optical effects would be reported. As a per-
         son approached the emission, it would have increasingly
         greater effect upon the human system, until finally, in the
         event an actual physical contact was made, the unfortunate
         individual might be electrocuted, and death would be attrib-
         uted by an unsuspecting coroner to lightning or contact with
         power lines (Persinger, 1979b).

                  STATISTICAL CORRELATIONS OF THE TST AND UFO
                                  OBSERVATIONS

         In several papers on the TST, its major proponent offers
         statistical arguments in support of the theory. The conclu-
         sions reached by some authors (e.g. Persinger 1983a, 1983b,
         1983c) seem to show that the variations in numbers of UFO
         reports vary with numbers of earthquakes:

                 "In general, UFO report numbers [tend] to increase two
                 to three years after decreases in geomagnetic activity
                 and the year after increases in the number of local,
                 low intensity earthtremors." (Persinger, 1981)

         The disquieting aspect of the TST is that the correlation
         is said to be due to "as yet unspecified processes associat-
         ed with tectonic strain (Persinger, 1981)", but the factors
         creating the variance are described as existing YEARS before
         an actual detectable seismic event. While this might be true
         in the sense that stresses leading up to an earthquake build
         over long periods of time, this suggests characteristics for
         the "unspecified processes" without clearly understanding
         the processes themselves.

                                   - 20 -

         In one paper, yearly totals for UFO "flaps" were taken
         from Fate magazine, tabulated earlier by the author (Per-
         singer and Lafreniere, 1977). Yearly totals for earthquakes
         of various intensities (MM: <III, III, IV, V, VI and >VI)
         were taken from U.S. Department of Commerce earthquake pub-
         lications, and yearly means for sunspot numbers were taken
         from the Journal of GeoPhysical Research. The total number
         of UFO reports used for analysis over a 15-year period was
         214, while the sunspot numbers ranged up to values near 1000
         per year, so their values were substituted by their square
         roots. Outliers of variables with a skewness greater than
         1.00 were recoded (i.e. given alternate values).

         The end result was that both the r and the r^2 values were
         generally high, with the r^2 values between 0.53 and 0.70 for
         the UFO/earthquake correlations (the r value is often called
         the "Pearson Product", which is the correlation coefficient
         and is an indicator of the dependence of one variable upon
         another). It was noted that although there was an overall
         trend in the data, some variables did not fall into the same
         pattern, showing regional differences. The results provided
         a pattern by which UFO report numbers were predicted for
         years beyond the study{3} (see figure 1; Persinger, 1981).

         __________
         {3} More predictions were made, based on studies of UFO re-
         ports from the years 1950-1975. "Missed" predicted UFO
         flap years were explained from a sociological perspective
         (Persinger, 1983d).

         A similar series of reported calculations was used in the
         study of UFO reports from the pre-Arnold period (pre-1947;
         specifically, 1820-1920), originally chronicled by a histor-
         ical researcher (Charles Fort) and compiled by the study's
         author (Persinger and Lafreniere, 1977). The yearly UFO re-
         port numbers were compared with yearly numbers of sunspot
         numbers and earthquakes. Once again, the correlation was re-
         ported as being very high, and that the relation "accurately
         classified more than 90% of the luminosity events (Persing-
         er, 1983a)." In dealing with the UFO data, several methods
         were used to correlate geophysical data. In one method, "all
         solar and seismic variables were lagged from 1 to 6
         [years]", while the "luminosity variables were not lagged or
         lagged 3 [years] (Persinger, 1983a)." The UFO data was also
         in a peculiar form: the number of reports per year was usu-
         ally less than three, "although [that] type of year was not
         very frequent (Persinger, 1983a)." Essentially, correlations
         were found between significant numbers of earthquakes (and
         sunspots) and one or two UFO reports in a particular year.
         Interestingly, the historical UFO reports took on various
         forms, including accounts of "phantom armies" in the sky.
         All the data were selected from Central western Europe in
         this study, including only the countries Germany, Austria,
         France, Italy and Switzerland, a geographical span of over
         1000 kilometres. The correlation results of this study are
         shown in figure 2.

         Yet another study involved the correlation of different
         types of UFO reports, according to the classification system
         employed by Saunders (1978). In this system, UFO reports are
         categorized by increasing levels of "strangeness" for types
         I to IX. A type I UFO report, for example, is merely a
         strange light in the sky, with a high probability of a con-
         ventional explanation such as that of a meteor, while a type
         IX report is a Close Encounter of the 3rd Kind, involving a
         reported contact with alien entities. Most UFO reports fall
         into types I, II or III.

         Each type of report was compared to levels of seismic ac-
         tivity with a "temporal increment" of six months, taken
         through the specific years examined for the study (Persing-
         er, unpubl). The results are shown in figure 3:

                 "All of the major types of [UFO report] classes were
                 significantly correlated with consequent increases in
                 V or less intensity earthtremors."(Persinger, unpubl)

         But the maximum r value is only near 0.50, so that the cor-
         responding r^2 value is near 0.25. This means that only 25%
         of the variance in UFO reports can be attributed to seismic
         events in this study. Even its author admits:

                 "This may indicate that a significant portion of the
                 [UFO report] variance for all types of classifications
                 may still involve non-seismic factors." (Persinger, un-
                 pub2)

                              ANALYSIS OF THE TST

         The TST proposes that many UFOs are produced by a strain
         field that is caused by crustal stress. This strain field is
         visibly indicated by a fracture (earthquake) that might oc-
         cur many kilometres distant and many days or even months
         separated in time and space from the point where the UFO was
         observed. It has been claimed that there is a statistical
         correlation between the numbers of UFO reports and earth-
         quake activity. In effect, an increase in earthquake activi-
         ty means an increase in UFO reports (Persinger, 1983a,
         1983b, 1983c, 1983d).

         But the statistical correlation works best when UFO re-
         ports from large distances are included. This is described
         as choosing an "optimal space and time increment". In a
         UFO/earthquake correlation study in the New Madrid earth-
         quake area, not only were the recognised New Madrid states
         included, but also those surrounding them as well. The sta-
         tistical study did find a good correlation for some years,
         but also found a "lag" for others (Persinger, 1983b).

                                     - 24 -

         Hence, this is the source of the suggestion that UFO re-
         ports are related to earthquakes through a common strain
         field that may cover a large area, so that the UFO may be
         observed hundreds of kilometres from the epicentre of an
         earthquake and still be related.

         But what exactly is the strain field responsible for the
         UFOs and the earthquakes? We know that crustal stress can
         build within rock through various processes, including tec-
         tonic and tidal force-related activities. This stress will
         accumulate in a certain area within the crust, the exact
         structure and dimensions of this area being dependent upon
         the local geology and the physical composition of the rocks
         involved. The actual mechanisms of crustal deformation is
         beyond the scope of this review, although some basic ele-
         ments have been considered in Chapter 2.

         Most sources agree that the size of the region strained
         to its breaking point prior to a fracture (earthquake) is
         about 20-50 km in radius, but this depends on the magnitude.
         Naturally, however, rock outside this area will be under
         some strain, but not enough to cause failure. There is no
         practical method for determining the exact extent of the
         strained region,{4} since the strain will never quite be zero,

         __________
         {4} There do exist some methods for estimating crustal stress
         from core samples, such as using the Xaiser effect to mon-
         itor acoustic emission, but underground conditions have
         been shown to be capable of altering stress determinations
         (Yoshikawa and Mogij 1981), so that these measurements
         will have their limitations.

                                     - 25 -

         even at large distances from the earthquake epicentre.
         Therefore, the determination of a "strain field" is quite
         arbitrary.

         If a "strain field" is in existence, then the TST implies
         that its major visible indicator is an earthquake. If this
         field is also responsible for the appearance of a UFO, then
         one can wonder why the UFO would not appear adjacent to the
         fracture site, where the most energy is released.

         Earthquake lightning is often observed concurrently with
         earthquakes, and although it may be theorized that UFOs are
         indicators of smaller fractures, the use of "optimal tempo-
         ral increments" to associate UFOs and earthquakes in a
         strain field tends to point out a lack of similarity between
         the two phenomena. Specifically, earthquake lightning is es-
         sentially simultaneous with an earthquake, while according
         to the TST, UFOs can appear much before or later. There-
         fore, earthquake lights are probably not upscaled versions
         of UFOs.


         4.1 ENERGY CONSTRAINTS

         In terms of energy involved, we can estimate the energy
         required to support a luminous, ball-like UFO. Assume that
         there is a luminous ball with a diameter of one meter. Sup-
         pose it radiates energy at a frequency near 1 x 10^14 Hz,
         corresponding to a wavelength of 5700 A, or yellow light.

                                     - 26 -

         Let us also suppose it has the power of a common 60-watt
         light bulb.

         To an observer 100 metres away, the object will have a
         flux of:

                   S = L/(4 pi r^2) = 4.7 x 10^-4 W m^-2

         This value is considerably more than that of the threshold
         intensity of the human eye, which is about 10^-14 W m^-2
         (Haines, 1980). If the object is seen for ten seconds, then
         abruptly disappears, its energy radiated is 6 J in the ob-
         server's direction.

         Now, since the object will subtend an angle of 1.146 de-
         grees, which is equivalent to 1.26 x 10^-3 steradians, its
         total energy output would have been about 6 x 10^4 J:

                   (4 pi E)/ W = E = 6 x 10^4 J

         and its energy density would have been 1.42 x 10^4 J m^-3.

         We can see, then, that even a relatively dim object 100
         metres from an observer will still be quite visible, but the
         energy requirements for such an object are not insubstan-
         tial. Even if an object radiated just at the threshold level
         for our 100 metres distance (about 1.25 x 10^-9 W), its con-
         tained energy would be 1.25 x 10^-6 J. These calculations as-
         sume an entirely efficient energy radiation mechanism, under
         ideal conditions. Any mechanism which aims to produce a vis-

                                     - 27 -

         ible luminous body will need to overcome the obstacles of
         energy requirements.

         Several researchers have reported on their results of ex-
         periments upon the fracturing of rock. They have consistent-
         ly found that electromagnetic emission is produced when rock
         is subjected to strain. However, the frequency of this em-
         ission varies greatly (Gol'd et al, 1975; Kuksenko et al.,
         1981; Perel'man and Khatiashvili, 1981; Sobolev et al.,
         1980; Volarovich et al., 1959).

         According to Demin et al (1981), the peak frequency of
         the piezoelectric pulse in a fracturing rock is 1.7 kHz.
         This would mean an energy of 1.12 x 10^-30 J. Its luminosity
         would be about 10^-31 W, and its flux would be (at 100 m)
         about 9 x 10^-33 W m^-2.

         Nitsan (1977) calculated the radiated power of a piezoe-
         lectric emission as about 10^-15 W at 5 x 10^6 Hz, and this
         would yield 8 x 10^-21 W m^-2 at 100 m.

         The problem here, though, is that this energy is produced
         within the crust at unknown depths. Radio wave propagation
         through rock is of the order of a few meters, unless one in-
         cludes such things as "natural circuits" and energy tunnel-
         ing. Even assuming that this energy could find its way to
         the surface, the method by which it would discharge into the
         atmosphere and exhibit UFO-like characteristics may not be
         possible.

                                     - 28 -

         Speculations have been made that the monitoring of EM em-
         ission could be used to predict earthquakes, interpreting an
         anomalous reading as a precursor. Although this may one day
         be a useful supplement to other precursory indicators, at
         the present time the parameters and the actual mechanism are
         both unresolved, so that it can only be regarded as a possi-
         ble factor for consideration (Gokhberg et al., 1983; King,
         1983; Sardarov, 1981).


         4.2 GEOGRAPHICAL IMPLICATIONS OF UFO SIGHTINGS

         A persuasive argument presented in favor of the TST is
         that seismic activity and UFO reports appear to be statisti-
         cally correlated in space and time. That is, seismically ac-
         tive areas will have accompanying high numbers of UFO re-
         ports. In the TST, however, a "lag" is sometimes introduced
         to compensate for the lack of a direct one-to-one correspon-
         dence within the data. An earthquake in an area is not ex-
         pected to be directlY associated with a particular UFO re-
         port. This makes the theory neatly unaffected by complaints
         that UFOs might not be observed near an earthquake epicentre
         at the time of the event (of course, since the reporting of
         UFOs is related to psychological and sociological processes,
         the number of variables influencing the eventual reporting
         of a UFO over a period of many months and within a large ra-
         dius is going to be considerable).

                                     - 29 -

         Actually, the existence of UFO reports within a large ra-
         dius of an epicentre need not be surprising. UFO reports ap-
         pear to be generally related to population density in some
         ways, and, as they are a significantly subjective phenomena,
         one would expect them to be related to other phenomena that
         involve similar subjective limitations. After all, Persinger
         (1983b) noted that the best results for the New Madrid area,
         for example, were strongest when states surrounding the New
         Madrid states were included. Is this because of a real se-
         ismicity-UFO correlation or because a larger radius means a
         larger population to report UFOs?

         It has also been said that: "the more intense the quake,
         the longer the lag back"(Persinger, 1980b), when referring
         to the TST, consistent with the theory and its strain field
         mechanism. But one can wonder, then, if a low intensity
         event will really imply a short lag between the event and
         the UFO observation. How well-defined is this relationship?
         How well are UFOs actually related to seismic activity?
         Since attempts have been made to demonstrate statistically
         that UFOs are related to seismically active areas, a logical
         step would be to determine if this is physically the case.
         Can we test the TST using other data? In particular, con-
         sistent with the TST is the suggestion that a seismically-
         inactive area should not be burdened with a plethora of UFO
         reports. Therefore, a seismically-inactive area, such as
         Manitoba, should not have a history of frequent UFO sight-

                                     - 30 -

         ings. But this is not the case, as there are a large number
         of UFO reports on record for the province (Rutkowski, 1983).

         The studies of Persinger (unpubl) show that all but the
         very-high-strangeness UFO cases could be correlated to se-
         ismic activity. The report sample of Ufology Research of
         Manitoba should therefore show some sort of relationship to
         seismic activity in the province and/or the surrounding
         area.

         Manitoba, however, is not known to be a seismically-ac-
         tive province, and there have been no earthquakes within its
         borders (Wilson and Brisbin, 1962).   Yet, over 500 Manitoba
         UFO reports are on file with UFOROM. How can this be recon-
         ciled with the TST?

         Persinger (1983b) includes a radius of up to 200 km be-
         tween earthquakes and UFO reports in his studies of statis-
         tical correlations. we must therefore incorporate this dis-
         tance into any comparative map of UFO reports and seismic
         events for Manitoba, including the surrounding provinces and
         states. However, within a radius of 200 km from the Manitoba
         border (not necessarily from UFO report sites), there have
         been only eight recorded earthquakes over the last 100
         years.{5} These earthquakes are listed in Table 1.

         __________
         {5} For the sake of completeness, we can include one addition-
         al event which occurred in 1880.

         Of these, only five (*) were considered near enough to UFO-
         prone areas to be consistent and viable through the TST
         (Gendzwill et al., 1982; Horner and Hasegawa, 1978; Reagor
         et al., 1981; Stover et al., 1981)(See Map 1).

         With regard to the year-by-year distribution of UFO re-
         ports for Manitoba, there were three major "flap years",
         namely 1952, 1967 and 1975, when report numbers climbed con-
         siderably above the normal background level. These years co-
         incide with "flap years" in other parts of the world, as
         agreed upon by other researchers, and are considered part of
         a world-wide trend (Rutkowski, 1983)(See Figure 4).

         The first observation that we can make is that there were
         no earthquakes within real "range" of Manitoba during these
         "flap" periods. Only one earthquake (7 Nov 1976) occurred
         within a 2-year interval of a flap year (1975), and this oc-
         curred 300-400 km away from the area which experienced the
         bulk of the reports (Carman). This means that no earthquake
         was related to a surge of UFO reports, even through the ac-
         tion of a moveable strain field, with the exception of one
         event that is more than likely a coincidence. Secondly,
         these were all low-intensity events, and highly-localized,
         so that they were not felt beyond a small radius.

         Given the large number of UFO reports in the province, it
         is not conceivable that they are related to seismic activi-
         ty. No statistical study is necessary in this case, since
         the lack of seismic events and the contrasting abundance of
         UFO data are not conducive toward conditions for analysis.
         In Manitoba, there can be no "optimal" temporal or spatial
         increment in analogue to the New Madrid area studied by Per-
         singer (1983b).

         In Map 2, the geographic locations of UFO reports in Man-
         itoba have been plotted. These represent more than 150
         places where over 500 reports have been made within the
         province since 1900 (Rutkowski, 1983).   Map 3 exhibits the
         rural population distribution for Manitoba (Weir, 1960). It
         is immediately obvious that, in general, the distribution of

         UFO reports within the province is similar, if not identi-
         cal, to the distribution of population. This is because the
         reporting of UFOs is through a human system. Since UFOs are
         reported by people, there will be a strong relationship be-
         tween the two elements.

         What do these maps tell us about the occurrence of UFOs
         in Manitoba? Since there are very few populated areas in
         Manitoba north of 52 degrees latitude, the lack of UFO re-
         ports means only that few people are present to observe UFOs
         if and when they appear. In fact, there seems more evidence
         for a UFO-demographic relationship than a UFO-geologic one.
         Determining a relationship between faults and/or seismic
         events and UFO reports appears geographically untenable, at
         least in Manitoba.

         We see, then, that UFO reports do not necessarily indi-
         cate seismic activity (this is, in fact, stated in the TST).
         In the TST, it is even possible that UFOs may be associated
         with unknown or undiscovered faults in the Earth's crust. In
         considering this possibility, a map of the faults in Manito-
         ba needs to be examined as well.

         Map 4 is a representation of major geologic fault systems
         in the province, showing that with the exception of two
         faults in the Whiteshell area, all are well over 200 km from
         the bulk of UFO report sites (Manitoba Mineral Resources Di-
         vision, 1979).

         In an early TST study (Persinger and Lafreniere, 1977),
         UFO report numbers were compared with "gravity anomalies",
         showing a reported correlation. Map 5 gives the relative
         intensities of gravity anomalies in the province. There are
         relative gravity highs in the densely-populated prairies,
         with large low anomalies in the extreme north and west parts
         of the province (Davies et al., 1962).

         It is apparent that there is a poor geographic relation-
         ship between faults and UFO report areas in Manitoba. This
         must mean, then, that there exist undiscovered faults in the
         UFO report areas, according to the TST. This is permissible
         in the TST, since it is the strain field which is the pro-
         duction mechanism for luminous phenomena. It has been pro-
         posed that these luminous ball-like UFOs may be earthquake
         lights associated with very small, local seismic events,
         with a magnitude less than 2 and perhaps even less than 1 on
         the Richter scale (Simon, 1983). Since there is always some
         amount of subsidence, release and buildup of small strains
         within the Earth's crust, the TST might be broadly embraced
         to explain all UFO phenomena. Not only could all luminous
         lights be explained by strain-related EM emission, but also
         all close-encounters where witnesses report bizarre experi-
         ences. This is so because EM emission has been shown to be
         capable of affecting the human brain, causing hallucina-
         tions. It appears that, at face value, the TST can be used
         to explain a phenomenon with a wide variety of characteris-
         tics.

         But why, then, if the strain produces UFO reports, is
         there not a more direct relationship between earthquakes and
         UFOs? Why would there not be a flurry of reports during se-
         ismic activity in the area near the epicentre?


         4.3 EARTHQUAKE LIGHTS AND DILATANCY HYPOTHESES

         The dilatancy model of strain precursors explains that it
         is the movement of water into microcracks within a strained
         area that causes dilation. Rikitake (1975) suggests it is
         even possible to calculate the size of the dilated area as
         crustal deformation. The formula for calculating this is:

                        M = 1.96 log r + 4.45

         where r is the radius measured in kilometres. Therefore, an
         (unmeasurable) event with a magnitude of 1 will have a radi-
         us of about 17 metres.

                                    r = 10^_B

         where _B = (M-4.45)/(1.96)

         ( a magnitude 4.45 event will have a dilatancy radius of 1
         km )

         The problem of UFOs being small, "local" earthquake
         lights is basic: their differing characteristics. Earth-
         quake lights are stationary and of very short duration, be-

                                     - 36 -

         ing associated with events at the time of the fracture, and
         appear at that time. UFOs, on the other hand, come in a
         myriad of colors, move erratically and are not visibly asso-
         ciated with any crustal movement.

         The TST argues that UFOs move as they do because the
         strain field they "belong to" moves in the same manner. How-
         ever, since UFOs have been reported to move with great
         speed, one wonders if a strain field could move with such
         velocity. Even fracture propagations (the earthquake mecha-
         nism) often take several days to travel short distances.

         TST proponents believe that the strain field could, in
         fact, react to geophysical processes including lunar tidal
         effects and geomagnetic field changes. These reactions could
         provide a moving force for the strain field, according to
         corollaries of the TST. The exact mechanism is not proposed,
         although it is assumed that it involves crustal movement as-
         socited with gravitic and magnetic attraction. In effect,
         the ground beneath a UFO is said to be affected (probably
         dilated) and as the strain field reacts, the dilation
         shifts, carrying the UFO with it. These microdilatory ef-
         fects are essentially too small to detect (and, in fact,
         there are no reported cases in geophysical literature), so
         that the only evidence we could have for their existence
         would be a visible UFO.

                                     - 37 -

         4.4 OTHER CONSIDERATIONS

         While it is true that there have been precursory dila-
         tions associated with shallow earthquakes, a major factor
         for consideration is the focal depth of the events. One
         would expect, naturally, that shallow earthquakes would show
         more precursory crustal deformation than deep events. One
         indication is the fact that at depths below 200 km, the na-
         ture of the earthquake focal mechanism itself is modified,
         so that dilation cannot easily occur (Kasahara, 1981).

         If in fact luminous effects caused by emissions are pro-
         duced by strain, then their association with deep-focus
         events would be very puzzling. Since attenuation of electro-
         magnetic waves through rock is often of the order of only a
         few metres, it is difficult to explain how emissions within
         a strained area could reach the surface and produce detecta-
         ble effects.

                           OTHER TST-RELATED THEORIES

         5.1 VESTIGIA

         A group whose work supports that of Persinger and paral-
         lels his research on the TST is Vestigia, a group of indi-
         viduals who have conducted independent studies into so-
         called "spook lights".{6} The group has often set up field
         experiments in areas frequented by these lights, using
         equipment such as geiger counters, methane detectors, infra-
         red sensors and radio detection equipment with several thou-
         sand feet of wire attached to an amplifier and an oscillo-
         scope. They have reported the detection of radio emission of
         40 kHz during the observation of yellowish-white lights
         along railroad tracks in areas with small faults or alluvial
         soils (Wagner et al., 1978).

         Their theory for the phenomenon is nearly identical to
         the TST:
                 "When quartz-bearing rock is subjected to stress...an
                 immense electrostatic charge is generated. At the
                 maximum periods of lunar tidal stresses (sic) this

         __________
         {6} It appears that Persinger has drawn upon Vestigia's re-
         sults and theories to some degree.

                                     - 39 -

                 effect would be more pronounced. If sufficient
                 electrical fields are created close to the surface, a
                 portion of the spherical field would be above the
                 surface. In a region where either faults or loose-
                 packed alluvial soils are present, radon gas would be
                 emitted into the air at the surface. This radioactive
                 gas would create partially "ionized" pockets of air
                 which would be enhanced by the highly electrified
                 fields in the region. This would, in turn, start a
                 low-energy plasma of small size which would be pre-
                 dominantly near railroad tracks or power lines that
                 traverse the terrain." (Wagner et al., 1978)

         The Vestigia group goes on to describe details such as
         colors of the lights, the effect of changes in atmospheric
         and the effect on humans in the proximity.

         Although the theory is well-described, little in the way
         of supporting physical mechanisms is given, showing more
         similarity with the TST. Vestigia has produced photographs
         of the lights and records of the instrumental detection of
         the events, as well as numerous witnesses' accounts. In sup-
         port of Vestigia, it should be noted that although many
         "spook lights" have been reported around the world, no sci-
         entific investigation of them has been conducted by the sci-
         entific community. Vestigia has gone to considerable length
         to document the phenomenon, and has produced a theory which

                                     - 40 -

         is consistent with the observations, although a quantitative
         assessment is certainly in order. The theory is subject to
         considerable constraints.

         Once again, it would be desireable to know the relation-
         ship between stress and energy production, and the energy
         requirements involved. Also, one would have to question the
         observations themselves, since Vestigia has described in one
         instance a "spook light" that was visible and detectable
         from only one direction (Wiedemann, 1977). The TST would
         here invoke the influence of EM emission upon the human
         brain to explain the appearance of a UFO to one person and
         not another, but the Vestigia theory leaves this question
         unanswered, although it has commented on animal precursors
         of earthquakes (Wagner et al., 1978).

         The Vestigia group has also expressed its view that
         electrostatic fields of the order of 10^5 V m^-1 could be gen-
         erated in quartz-bearing rock under stress. They include
         piezoelectricity in their approach as well, and describe a
         relationship between earthquakes and "spook lights". Specif-
         ically, they found that 80% of recorded "spook lights" cor-
         respond to "regions of extensive earthquake activity". But
         they realized that the other 20% would constitute a problem.
         They were encouraged, however, by the finding that a light
         in South Carolina not on a previously recognized fault was
         in fact on a fault discovered after the light's documenta-
         tion.

                                     - 41 -

         In April of 1978, some of Vestigia's consultants present-
         ed a paper to the American Geophysical Union meeting on
         "earth stress lights", and as a result of their studies, an-
         nounced: "we now [have] introduced to the scientific commu-
         nity a realistic explanation for luminous occurrences in
         earthquake regions" (Wagner and Visvanathan, 1978).

         As well, based on their "spook light" research and proba-
         bly also due to the success of a light "predicting" a fault,
         Vestigia commented that:

                 "Possibly within the next 10 years, THERE WILL BE AN
                 EARTHQUAKE in Florida, S.E. Texas and S.E. Maryland."
                 (Wagner et al., 1978)

                 (emphasis in original)

         Vestigia's theory is actually preferable to the TST in
         some ways because it focusses on only one type of UFO, the
         "spook light", which has its own individual characteristics.
         Statistical studies involving the TST have used raw UFO data
         from UFO report catalogues, incorporating a wide variety of
         characteristics, and hence may involve several different
         phenomena.

         5.2 EARTH LIGHTS

         Another group of researchers doing independent research
         into strain-related luminous phenomena are involved in the
         Dragon Project. Involved are: Don Robins, an inorganic che-
         mist; Paul Devereux, an archaeological researcher and writer
         about UFOs; and Paul McCartney, a geochemist. The Dragon
         Project cites the work of Persinger and Brady{7} in support of
         their own research into the relationship between UFOs and
         geophysical phenomena. But these two groups of researchers
         have rather marked distinctions.

         Firstly, the Dragon Project is primarily interested in
         the petroforms of England, including Stonehenge, Rollright
         and other megalithic sites (Devereux and Forrest, 1982).
         The researchers believe that they have found that "stone
         circles...emit anomalously high and anomalously low lev-
         els... of radiation. (Robins, 1982)" Combined with this ra-
         diation is also ultrasound production, detected at some
         sites (Robins, 1982). What has been found is that certain
         sites give geiger counter readings at levels above the nor-
         mal background, while at some sites, the background is unus-
         ually low. The Dragon Project has put forth the concept of
         "Earth energy", which is more mystical than mechanical. This
         "Earth energy" is reportedly detected by dowsers and psy-
         chics, and permeates all things in analogy to the famous

         __________
         {7} Specifically, Persinger and Lafreniere (1977) and Brady et
         al (unpub).

                                     - 43 -

         "ether" of the ancient philosophers (Robins, 1982).

         One of the proponents of this energy, Devereux (1982),
         combined the concept of radiation emission with that of
         UFOs. Devereux and his associates carried out several ex-
         periments (all with unpublished details and results) in
         which they crushed a specimen of rock and observed lights
         produced during the process (Devereux et al., 1983). In
         this way, they were able to "confirm" the results of Brady
         et al (unpub).

         Frequently referring to Persinger's research, Devereux
         (1982) found "the best UFO-geology correlations yet pub-
         lished". He found that many UFO sightings in Wales occurred
         within a few hundred metres of a fault. But he makes a
         quantum leap from faults to earthquake lights at one point
         (citing Derr (1977)), and links the TST with his research
         (Devereux, 1982).

         Devereux, however, makes one distinction in that he disa-
         grees that piezoelectricity is the causative mechanism for
         UFOs. He suggests triboluminescence "as a more likely candi-
         date" (Devereux et al., 1983). The two processes are differ-
         ent mechanisms, but both produce luminous phenomena in min-
         erals. Piezoelectricity is created when certain crystals are
         subjected to pressure, while triboluminescence is the effect
         caused by mechanical friction upon two mineral surfaces.

                                     - 44 -

         Devereux, although claiming to have duplicated Brady's
         experiments, describes a photograph of "triboluminescence in
         rock crystal...after it has been subjected to friction (Dev-
         ereux et al., 1983)." But Brady (Brady et al., unpub) sub-
         jected his granitic core sample to pressure, a different
         mechanism. There appears to be a lack of distinction here,
         and a probable contributing factor to this confusion is the
         fact that the experimental results of neither Brady nor Dev-
         ereux have been formally published.

         A further similarity between the TST and EL (Earth
         Lights) theories is that the latter includes the possibility
         that the energy that "creates" the EL may effect the human
         brain. In this regard, the EL theory claims that psychics or
         "sensitives" might be more apt to perceive these energies
         than other people (Persinger, 1975). Although no actual
         mechanism is proposed, the implication is that the "Earth
         energy" acts upon the brain in a method in agreement with
         that proposed by the TST.

         It is clear, then, that the EL theory parallels the TST
         in many ways. A significant difference is that the EL theo-
         ry restricts "Earth energy" effects upon human systems to
         distances generally less than 1 km, whereas the TST involves
         faults and/or events up to 200 km away from an observer.

                                   Chapter VI

                                  CONCLUSIONS

         The TST (Tectonic Strain Theory) is a theory with minimal
         supportive evidence, but with wide appeal for individuals
         wishing to explain a persistent phenomenon in terms of known
         mechanisms. While elements of the TST appear to include doc-
         umented geophysical phenomena, the main thrust of the theory
         hinges on its unproved relationship with a controversial
         phenomena, namely UFOs. For a theory of its kind, the TST
         has received a large amount of publicity and a generally un-
         contested entrance into published scientific literature.
         This situation has resulted in an apparent acceptance of the
         theory's "principles" without proper scientific comment.

         Although statistics on UFO reports have been kept for
         nearly forty years (and much earlier, if we include pre-1947
         reports), the data are without many redeeming features. Data
         sources such as UFOCAT and MANUFOCAT contain many reports
         with poor investigation or insufficient information due to
         the methods used in obtaining the data. For example, many
         entries in UFOCAT are from published articles or newspaper
         clippings, and not necessarily from an investigator's re-
         port. Many reports are therefore anecdotal rather than fac-
         tual (Rutkowski, 1983).

                                     - 46 -

         Even in the case of entries copied from investigators'
         files, the problem of consistency remains. The quality of
         investigative effort is expected to vary, since essentially
         anyone could call his- or herself an "investigator", regard-
         less of qualifications, and submit reports for entering into
         the file. Although this is not as true today, with efforts
         for standardization in preparation, the lack of training
         could easily account for judgement errors in early case
         files. Admittedly, this was not always so; the files contain
         many greatly-detailed reports from good investigators (in-
         cluding law enforcement officials) (Hendry, 1979).

         They may, in fact, have been good reason for lower-stan-
         dard investigations. Most UFO investigators and researchers
         are not funded for their efforts, so lack of travelling ex-
         penses might preclude many investigations. Some might lack
         the experience to identify high-flying aircraft and their
         descriptions. Others might include their own personal bias
         in their report (e.g. by asking a witness: "How big was the
         craft?" rather than "What was the angular size of the ob-
         ject?"). Still others might just make a judgement error.

         All of these problems with UFO data are found in all UFO
         report listings. It is details such as these which have led
         one UFO researcher to comment that UFOCAT is not useable for
         statistical studies of UFO data because of inherent flaws in
         its design (Hendry, 1979). Yet, the TST uses several UFO

                                     - 47 -

         data sources for statistical correlative studies, with very
         vaguely-defined parameters.

         There is no question that some of the geophysical pro-
         cesses invoked in the TST are sound. Rock undergoing strain
         can indeed give off EM radiation that can be detected by
         sensors near the event. Whether this EM emission is scale
         invariant is an entirely different matter.{8} There is also no
         question that earthquake lights exist, and that their mecha-
         nism is not fully understood. The TST suggests that UFOs are
         essentially the same phenomenon, and it has been proposed
         (in a questionable manner) that the statistical correla-
         tion between UFOs and earthquakes is supportive of the theo-
         ry (Persinger, 1983a, 1983b, 1983c, 1983d).

         But the existence of UFOs in aseismic areas seems to con-
         tradict this correlation. To suggest that the seismic activ-
         ity exists in these areas with magnitudes less than 2 (or
         even 1) on the Richter scale is perhaps grasping for straws.
         Certainly, activity in the range of magnitude 1 can occur
         frequently in many areas, so that the observation of UFOs
         should be at a constant value. While it is true that UFO re-
         ports have a "background" level, this is more the case of
         reporting rather than the reports themselves as the main
         contributors.

         {8} Brady (1973, 1974), has given evidence to show that strain
         itself may be scale invariant. Whether this might include
         EM emissions is not clear.

                                     - 48 -

         Also, there are different characteristics of earthquake
         lights and UFOs that need to be considered. Earthquake
         lights are reported as generally stationary hemispheres of
         white light, in contact with the ground. They are 20 to 200
         metres in diameter, and follow an earthquake, with a dura-
         tion of 10 to 100 seconds. They do not occur at an epicen-
         ter, but in areas around it at varying radii (10 to 50 km),
         and frequently on mountaintops (Derr, 1973, 1977; Hedervari,
         1982). UFOs, by definition, are seen in the air, and are
         observed in areas where no earthquake is felt. They are most
         often described as spherical, with the next most frequent
         shapes reported being point sources, discs and cigars.
         There are two main distributions of sizes: <1 metre, and >4
         metres. Red, white and orange, in that order, are the most
         frequently- reported colors of UFOs. The duration of a UFO
         sighting ranges between a few seconds up to an hour or more
         (Hendry, 1979; Rutkowski, 1983).

         A comparison of the characteristics of the two phenomena
         shows they do differ significantly and that any attempt to
         reconcile these differences needs to properly address the
         dissimilar features.

         In an early study where a form of the TST was first de-
         scribed, not only were geophysical events correlated with
         UFOs, but also unusual objects falling from the sky, EM ef-
         fects, unusual human talents, telekinetic events and ghost
         sightings. In the early study, it was said that:

                 not necessarily involve areas of well-known seismici-
                 ty, since these areas may only reflect structural
                 weakness along the stress axis." (Persinger and Lafre-
                 niere, 1977)

         It was implied that most unusual phenomena were related to
         geophysical processes.

         Interestingly, Devereux (1982), himself a proponent of a
         form of the TST, asks of Persinger's research:

                 "Why attempt to explain other, possibly more complex
                 and perhaps unrelated mechanisms under the same con-
                 ceptual umbrella?...This approach to the UFO problem
                 cannot sensibly be conducted over the entire USA in
                 any case - the area is so vast that untenable numbers
                 of UFO events would have to be involved. And how would
                 one cope with the detailed geological data of such a
                 continental area, even if it is available?" (Devereux,
                 1982)

                 (emphasis in original)

         He concludes:

                 "...despite all the scientific trappings [the] work
                 displays, the conclusions drawn owe as much to intui-
                 tion as to the computer..."

                                     - 50 -

         This represents perhaps the most succinct published crit-
         icism of the TST on record.

         One of the few other criticisms of the TST, this time di-
         rected at Devereux et al. (1983), was by Campbell (1983). He
         pointed out that "since Britain is criss-crossed with geo-
         logical faults, it is not surprising that 'many reports of
         UFO sightings come from areas close' to them." He cautioned
         that Devereux "should be as concerned with the UFO data as
         [he is] with geology," since Persinger's data base was
         flawed, and that "the geological jargon conceals a poverty
         of hypotheses."

         Devereux quickly countered by saying that surface fault-
         ing does not cover Britain as Campbell implies, and that he
         did not think that the UFO/fault relationship was coinci-
         dence. He also came to Persinger's defense by calling his
         work "meticulous", and saying that:

                 "If [UFOs are] all hoaxes or hallucinations, then we
                 had better start wondering why figments of the imagi-
                 nation correlate with faulting."(Devereux, 1983)

         Of course, the problem is not that UFOs are hoaxes or hallu-
         cinations (few are), but that the majority are misidentifi-
         cations.

         In the end, the major problem is that of the data itself.
         We know that seismic activity exists, and that earthquake

                                     - 51 -

         lights exist, and that UFO reports exist. But the data for
         these phenomena is taken from a variety of sources and cov-
         ers a variety of disciplines.

         The handling of data has always been a problem, and sev-
         eral statisticians have cautioned against its misinterpreta-
         tion.
                 "When...probabilistic considerations seem to be called
                 for, we now feel more hesitant about postulating sim-
                 ple parametric distributions. We are not now so sure
                 that there is a likelihood function, or a set of suf-
                 ficient statistics, or an exact test of signifi-
                 cance...Thus we view data with greater respect, with
                 greater curiosity about what is there; and we have
                 less confidence that we know just what questions
                 should be answered and in what way." (Anscombe,1982)

         While the TST is very appealing in its description of UFO
         phenomena in terms of "terrestrial", rather than "extrater-
         restrial" mechanisms, it provides little in the way of sup-
         portive evidence that its mechanism actually exists. As a
         hypothesis, it cannot be discounted; only the evidence in
         its support can be evaluated as either favorable or not fav-
         orable. But using one poorly-understood phenomenon to ex-
         plain another using an unknown mechanism is perhaps too much
         to expect at this point (Rutkowski, 1984).{9}

         It is possible that the TST may explain some aspects of
         the UFO phenomenon, but the theory needs a great deal of re-
         fining and rethinking before it can be applied in general to
         the phenomena it incorporates.

           Geophysical Variables and Human Behavior: Some Criticisms

         Through statistical studies of geophysical phenomena and UFO
         (Unidentified Flying Object) reports, it has been suggested that
         some reports of UFOs might reasonably be understood on the basis
         of natural phenomena produced by a geophysical process involving
         tectonic strain (Persinger, 1979, 1980, 1981, 1983a, 1983b,
         1983c). This theory, hereafter referred to as the TST (Tectonic
         Strain Theory) of UFOs, suggests that plasma-like luminosities can
         be naturally created and that these can be reported as UFOs. The
         TST is laudable in that it attempts to explain the persistent
         reports of UFOs in terms of "terrestrial" rather than
         "extraterrestrial" causes.

         The theory incorporates luminous effects that are a great distance
         from the source and temporarily displaced. This theory also
         contends that the luminous effects are related to geophysical
         variables such as the solar wind and geomagnetism. The geophysical
         basis for such a theory, however, is not strong and is extremely
         dependent upon recent reports of luminous effects produced by
         strain on rock during fracture tests (Demin et al., 1981).3 These
         effects are highly localized, of short duration and have not been
         demonstrated to be related to other geophysical phenomena such as
         the solar wind. Despite this, statistical studies using seismic,
         solar and UFO data as variables have been performed, and it has
         been proposed that UFO report numbers vary with the seismic and
         solar data (Persinger, 1981). These correlations are suggested to
         be consonant with the TST.

         There are several problems with obtaining adequate data to test
         the theory which are worth noting. The statistical studies which
         suggest a

                                    ...3

         correlation between UFO report numbers and geophysical phenomena
         show the best relationships between the variables only when the
         optimal /\ t and /\ s (increments of time and space) are used. In
         particular, it has been proposed that the geophysical cause for
         UFOs in the TST is a strain field which may extend hundreds of
         kilometers between the locations of the perceived UFOs and
         earthquake epicenters. Statistical correlations use these UFO
         report numbers and earthquake numbers to define relationships
         between the variables, often including a time lag of up to a year.
         Essentially, an observed UFO at point p may be the result of a
         strain field and may be related to an earthquake at point q, two
         hundred kilometers distant and several months previous to the time
         of observation. This is intuitively unsatisfying, since if two
         variables can occur at any time within a year of observation and
         anywhere within a large radius, it would be difficult to determine
         a time-geography variable in order to arrange a correlation study.
         Countless other variables may be present or occur within the
         strain field's perimeter, and these may influence any correlated
         effects.

         It should be noted that a rare geophysical phenomenon called
         earthquake lighting displays some reported UFO characteristics
         such as luminous bodies of light (Derr, 1973). However, earthquake
         lightning appears generally within a short time before or after an
         earthquake, so it has a more readily-apparent cause. In addition,
         there exist several theories as to the origin of earthquake
         lightning, encompassing geological processes familiar to
         geophysicists (Finkelstein, et al., 1973). More serious problems
         concern the actual selection of UFO data. The studies make use of
         UFO report numbers from several sources with

                                    ...4

         varying degrees of credibility (e.g., Fate magazine and UFOCAT).
         In all cases, there is a great difficulty in trying to establish
         whether an object is actually unidentified or merely
         misidentified. The two different categories are often within the
         same data set in the UFOCAT file, for example. The fact remains
         that UFOs are often reported by inexperienced observers, and the
         reports are often investigated by inexperienced investigators.
         Statistical studies of raw UFO data, including the UFOCAT file,
         have shown that about 90% are misidentifications of ordinary
         phenomena (Hendry, 1979; Hynek, 1977). It has been stated that the
         UFOCAT file cannot be used as a source of data because of inherent
         flaws in its design (Hendry, 1979).

         The TST is therefore not supported by the statistical studies
         involving UFO data. Although geophysical phenomena could account
         for some UFO reports, a persuasive covariance has not been
         produced. On a more positive side, while the TST may not predict
         the presence of plasma-like luminosities, it may say something
         about the witnesses who report UFOs. In this regard, it has been
         suggested that geophysical luminosities are related to EM
         (electromagnetic) radiation, also produced by tectonic strain
         (Persinger, 1983c). This EM radiation is thought to be capable of
         affecting the human brain (in particular, the temporal lobe) and
         creating a variety of effects, including artificial memories. If
         the theory can show a relationship between misidentifications of
         ordinary phenomena and geophysical effects, perhaps there is,
         after all, some interaction between these phenomena and the human
         brain, causing individuals to report UFOs.

                                    ...5

         Care should be taken in further studies of UFO data because their
         nature is subjective and collection involves several problems.
         Theories such as the TST are quite valuable in their attempt to
         explain UFOs from a scientific standpoint. The TST probably could
         explain some UFO reports and elements of the total UFO problem,
         but the persuasiveness of an empirical scientific argument can be
         no better than the acceptability of the data upon which it is
         based.
