California landslides
From Wikipedia, the free encyclopedia
Landslides in California occur mainly due to intense rainfall but occasionally are triggered by earthquakes. Landslides are common in Southern California, the San Francisco Bay Area and other parts of Northern California, and the Sierra Nevada. Although they most often are reported when they impact residential developments, landslides also damage roads, railroads, pipelines, electrical lines, and other infrastructure throughout the state, and occur in unoccupied parts of the state.
