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 | |
