Landslides. Artwork showing different types of mass movement, the downslope movement of rock and soil under the influence of gravity. From left: soil creep, a gradual movement, causing its distinctive effects of leaning poles, curved tree-trunks and broken walls; slumping, where material slides down a curved surface, producing scarps (small crescent-shaped cliffs); a lahar or mudflow, a fast movement often triggered by earthquakes or volcanic activity; debris slide, shown here as triggered by deforestation which has increased surface erosion; and rock movements (rock fall, rockslide and avalanche), the fastest type of mass movement.
