Summary

Landslides are a characterized as the falling or movement of soil or rock down a slope and can manifest through mudflows, mudslides, debris flows, rock falls, rockslides, debris avalanches, debris slides, and slump-earth flows.[1] This movement occurs when the down-slope force exceeds the strength of the soil or other material holding the slope together[2] Typically, landslides take time to initiate movement as the soil saturates and ultimately moves at a slow pace, but can cause significant damage to buildings and other infrastructure. [3] Debris flows, a type of landslide, occur suddenly with shorter and intense rainfall creating a slurry that moves at a rapid pace and often can result in loss of life making them more dangerous.[3]
