see landslidelandslide,
rapid slipping of a mass of earth or rock from a higher elevation to a lower level under the influence of gravity and water lubrication. More specifically, rockslides are the rapid downhill movement of large masses of rock with little or no hydraulic flow, similar to

a thin (up to 1 m thick) soil layer or drift and eluvial formation that moves (flows) down a slope under the influence of gravity as a result of saturation by meltwater, rainwater, or groundwater until it assumes a mudlike state. Mud-flows usually occur on smooth, unsodded slopes and on railroad embankments.


A flowing mass of fine-grained earth material having a high degree of fluidity during movement.


Movement of soft weak soil having the consistency of mud.
