Landslides A landslide is a movement of rock or debris down a slope along one or more distinct surfaces. Landslides range in speed from 1 m/day to as much as 300 km/hr. Rockfalls Rockfall (free fall of rock) is an extremely rapid process and occurs without warning. Rockfall is typically the result of frost wedging.

landslide | Definition, Types, Causes, & Facts | Britannica

landslide, also called landslip, the movement downslope of a mass of rock, debris, earth, or soil (soil being a mixture of earth and debris). Landslides occur when gravitational and other types of shear stresses within a slope exceed the shear strength (resistance to shearing) of the materials that form the slope.. Shear stresses can be built up within a slope by a number of processes.
