Partial view of the San Gabriel Mountains and the valley below covered in dust clouds after the 1971 San Fernando earthquake. Widespread landslides and rock falls blocked many highways in the area. Landslides are another form of geological damage that often occurs during earthquakes. Landslides occur in areas of rocks that are either inherently weak or are weakened by joints, faults, or bedding planes.
