FOR IMMEDIATE RELEASE Sept. 17, 1990
Five JPL and U.S. Geological Survey scientists this
week are joining a team of Soviet scientists to study
volcanoes along Russia's Kamchatka Peninsula -- one of the
most active and complicated volcanic regions in the
world.
The joint study marks the first time that western
scientists have been allowed in the southern Kamchatka region
since
World War II, and signals the start of new U.S.-Soviet
program to better understand volcanoes in the Pacific's "Ring
of
Fire" -- volcanoes and other tectonic features located along
the edges of the Pacific Plate. The plate's boundaries
include the western coast of North America, the Aleutian
Islands, the Kamchatka Peninsula, Japan and New Zealand.
The Kamchatka Peninsula is both remote and home to
sensitive Soviet military installations, factors that have
discouraged study of the area's volcanoes by Soviet
scientists and, until now, has kept the area off-limits to
Western researchers. As a result, "Kamchatka is sort of a
missing link in our knowledge of the Pacific Ring of Fire,"
said Dr. David Pieri, the JPL geologist who heads the
American team.
"The volcanoes there are big, they're dangerous,
and they do explode," said Pieri. Situated near a major air
traffic lane that runs roughly along the northeast coast of
Asia, the volcanoes often eject ash into the stratosphere,
posing a threat to aircraft. Increased air traffic in the
area warrants new studies of the potential volcanic hazard,
Pieri said.
On this trip, the American team is participating in
joint field reconnaissance mapping of the region with
logistical support supplied by Aeroflot and the Soviet air
force. The Soviet
team is from the Institute for Volcanology of the USSR's
Academy of Sciences, Far Eastern division, in Petropavlovsk-
Kamchatskii. The mapping will identify areas of interest for
proposed subsequent joint airborne and orbital mapping of
Kamchatka-area volcanoes and volcanically active regions in
the U.S.
Participants from JPL are Pieri and Dr. Anne Kahle.
From the U.S. Geological Survey are Dr. Jack Lockwood of the
Hawaii Volcanoes Observatory; Dr. Dan Miller of the Cascade
Volcanoes Observatory, Vancouver, Washington; and Dr. Tom
Miller, Alaska Volcanoes Observatory, Anchorage.
Plans call for the Soviet team to visit the U.S.
early next year for similar field work in Hawaii or Oregon,
to be followed by more extensive joint field work in
Kamchatka in late summer of 1991.
The U.S. portion of the effort is funded by NASA
and the U.S. Geological Survey.
