Landslide

The term "landslide" describes a wide variety of processes that result in the downward and outward movement of slope-forming materials including rock, soil, artificial fill, or a combination of these. The materials may move by falling, toppling, sliding, spreading, or flowing.

Landslide

La Conchita, coastal area of southern California. This landslide and earthflow occurred in the spring of 1995. People were evacuated and the houses nearest the slide were completely destroyed. This is a typical type of landslide. Photo by R.L. Schuster, U.S. Geological Survey.

Landslide

Debris litters a crumbled road after landslides destroyed hundreds of homes in the Kupini and Valle de las Flores neighborhoods in La Paz (map), Bolivia, in 2011. According to the Associated Press, thousands of people were affected by the landslides, which had been triggered by heavy rains.
