Southern California lies astride a major tectonic plate boundary defined by the
San Andreas Fault and numerous related faults that are spread across
a broad region. This dynamic tectonic environment has created a spectacular
landscape of rugged mountains and steep-walled valleys that compose much
of the region’s scenic beauty. Unfortunately, this extraordinary landscape
also presents serious geologic hazards. Just as tectonic forces are steadily
pushing the landscape upward, gravity is relentlessly tugging it downward.
When gravity prevails, landslides can occur.
