Slumps. (A) Slumps can be triggered by earthquakes or heavy rains. Their downhill rate of movement ranges from millimeters per day or less to several meters per minute. They range in size from a few meters to a few kilometers across. (B) This slump occurred in Stone Canyon near Los Angeles. Heavy spring rains were blamed for the slump.
