Landslides are another hazard that results from mass wasting.
The technical term for a landslide is sediment flow, which better describes the fluid nature of its composition and movement. Movement sediment flows are a mixture of rock debris, water,and air that flow downhill. Sometimes the movement is a scarcely noticeable centimeter per year. Other times, a volatile mixture of heavy rains and loose sediments creates high velocity mudslides reaching up to eighty kilometers per hour. A tropical storm in 1985 caused a mudslide that buries over 100 homes in Puerto Rico.
