The movement of rock, debris or earth down a slope results in landslides.
Slopes, the bottom of slopes and canyons are examples of locations that may be prone to landslides and mudflows. Landslides also result from the failure in the structure of the materials which make up the hill slope and are driven by the force of gravity.
Human activities such as mining, building, and road constructions have often exposed the land and slopes to landslides.
