WebA landslide dam or barrier lake is the natural damming of a river by some kind of landslide, such as a debris flow, rock avalanche or volcanic eruption. [1] If the damming landslide is caused by an earthquake, it may also be called a quake lake. Some landslide dams are as high as the largest existing artificial dam. [2] Causes [ edit] WebThe term landslide includes a wide range of ground movements, such as rock falls, deep failure of slopes, and shallow debris flows. Although gravity acting on an over …
WebA landslide is a mass movement of material, such as rock, earth or debris, down a slope. They can happen suddenly or more slowly over long periods of time. When the force of gravity acting on a slope exceeds the resisting forces of a slope, the slope will fail and a landslide occurs. External factors can lead to landslides happening, including:

They range in character from sloppy wet mudflows to slurries of rock debris similar in texture to wet concrete. Debris flows begin on steep slopes of … Web30 mei 2024 · The three shallow landslides that triggered the debris flow have their upgradient portions in moderate slopes (38–61%, or 21° to 31°), while those originated in steeper slopes (> 61%, or > 31º) did not initiate an event in the other tributaries, probably due to thinner residual soils and colluvium (i.e., less material to generate a debris flow).
