A landslide is a mass-movement phenomenon in which soil, rock, regolith, or debris moves downslope under the influence of gravity, often along a discrete shear surface or failure plane. It encompasses diverse mechanisms such as rotational and translational slides, debris flows, rockfalls, and avalanches, typically initiated when driving forces exceed resisting forces due to factors like pore-water pressure increase, seismic shaking, weathering, or anthropogenic slope modification. Landslides are characterized by rapid to extremely rapid kinematics, spatial heterogeneity of displacement, and strong dependence on lithology, structural discontinuities, hydrological conditions, and topography, and are central to geomorphological evolution and natural hazard assessment.
The cliffs that comprise much of California's coastline are constantly being reshaped by rain, waves and other geologic forces. The erosion of cliffs threatens critical infrastructure such as highways, railways, homes, parklands, ...
