This MPEG simulation sequences a 1997 slump in San Mateo County,
located within the San Francisco Bay Area. After a long period
of rain, a fissure opened at the crest of the slope and the
slump progressed down hill. The animation captures movement over
an eight day period with an average movement of a few feet per
day. Over 250,000 tons of rock and soil moved in this landslide.
