Usually erosion. Erosion is when rocks and soil crack and break off due to high amounts of pressure from water. Also can be called a mudslide.
Seismologists use seismograms to calculate when an earthquake started. AND EARTHQUAKES START WHEN ROCK SLIPS SUDDENLY ENOUGH ALONG A FAULT TO CREATE SEISMIC WAVES!
A landslide.
The four types of mass movements are: Rock Falls-a rock fall happens when loose rocks fall down a steep slope Landslides-the sudden movement of rocks and soil down a slope Mudflows-the flow of a mass of mud or rock and soil mixed with a large amount of water Creep-the slow downhill movement of weathered rock material
Landslide
The type of erosion that occurs when gravity alone causes rock or sediment to move down a slope is called mass movement. The types of mass movement are creep, slump, rock slides, and mudflows.

Subduction zones are locations where crustal plates are being forced down into the mantle below other crustal plates. These movements are not uniform, but instead occur in discrete events. This is because friction causes the plates to lock in position until the stress exceeds the shear strength of the fault zone. This accumulation of stress causes deformations in the rock mass around the locked fault which is suddenly released when the fault slips.
Weathering makes rocks at the top of a cliff suddenly fall.
A landslide.
It suddenly slips when the stress across it becomes too high, which produces a sudden series of shockwaves that radiate in all directions from the fault through the surrounding rock. The earthquake you feel happens when these shockwaves reach the surface.
