A landslide in which the sliding surface is located within the soil mantle or weathered bedrock (typically to a depth from few decimeters to some meters) is called a shallow landslide. Debris slides and debris flows are usually shallow. Shallow landslides can often happen in areas that have slopes with high permeable soils on top of low ...
A landslide, also called a landslip, [10] is a relatively rapid movement of a large mass of earth and rocks down a hill or a mountainside. Landslides can be further classified by the importance of water in the mass wasting process. In a narrow sense, landslides are rapid movement of large amounts of relatively dry debris down moderate to steep ...
Rock slides are the most dangerous form of mass-wasting because they incorporate a sudden, incredibly fast-paced release of bedrock along a uniform plane of weakness. These uniform weaknesses are key to identifying rock slides because unlike slumps, flows, or falls, the failed material moves in a fairly uniform direction over a layer of solid ...
In his latest report, he noted that the landslide continues to affect new areas, moving in some spots as much as 13 inches a week. For decades, most areas saw movement closer to a few inches a ...
The largest volcanic landslides on Earth occur from submarine volcanoes and are several times larger than those that occur on land. Submarine landslides with volumes of 100–150 km 3 (24–36 cu mi) have occurred in the Canary Islands within the last 43 million years, but the largest submarine landslides could have been up to 900 km 3 (220 cu ...
"Landslide movement continues to manifest at the ground surface in the form of scarps, fissures, grabens/sinkholes, tensional cracking, shear zones and thrust features," the city's latest report ...
Mandatory evacuations are underway in the southeastern Alaska city after a landslide leveled buildings leaving at least one person dead and 3 hurt.
In traditional usage, the term landslide has at one time or another been used to cover almost all forms of mass movement of rocks and regolith at the Earth's surface. In 1978, in a very highly cited publication, David Varnes noted this imprecise usage and proposed a new, much tighter scheme for the classification of mass movements and ...
