A geological fault line stretching for 1,125
km/700 mi in a NW-SE direction through the
state of California, USA. Two sections of the
Earth's crust meet at the San Andreas fault,
and friction is created as the coastal
Pacific plate moves NW, rubbing against the
American continental plate, which is moving
slowly SE. The relative movement is only
about 5 cm/2 in a year, which means that Los
Angeles will reach San Francisco's latitude
in 10 million years. The friction caused by
this tectonic movement gives rise to periodic
earthquakes.
