landslides
definition: A landslide is defined as the rapid downslope movement of slope-forming materials—rock, soil, debris, or combinations of these materials. In regions of the world where steep slopes combine with heavy-moisture episodes, mass movement and landslides are a risk. [Source: Encyclopedia of Geography; Landslide]
