a large flow of rock, soil, and debris, typically slow-moving.
The sudden fall of rock and earth from a hill or cliff. Often triggered by an earthquake or heavy rain.
rapid sliding of large masses of bedrock on steep mountain slopes
A downslope movement of rock and soil over a failure surface and under the influence of gravity. Slumps, earthflows, debris flows and debris slides are examples.
A general term for relatively rapid types of mass movement, such as debris flows, debris slides, rock slides, and slumps.
The downhill movement of a mass of soil or rock, usually wet or saturated, that results in episodic erosion. (Sometimes simply referred to as "slide," but also including falling or flowing masses as well.)
Term used to describe the downslope movement of soil, rock, and other weathered materials because of gravity.
a mass of loose rock and soil that slides down a steep slope
A mass of soil and rock that moved downslope by gravity.
A mass of surface rock, soil or sediment that becomes detached and moves downslope along a slip plane. The mass remains mainly whole, but may have considerable internal deformation.
mass movement of unstable earth and rocks down the side of a slope. Can be initiated by long rains or in combination with an earthquake.
The failure of a slope bank in which the movement of the soil or rock mass takes place along a plane of sliding (slide plane).
a massive and more or less rapid sliding down of soil and rock.95 In general, all varieties of slope movement, under the influence of gravity; more strictly refers to down-slope movement of rock and/or earth masses along one or several slide surfaces.96
a slide of a large mass of dirt and rock down a mountain or cliff
a downward and outward movement of a SOIL mass that formed part of a slope
a downward movement of a land mass from a slope
a downward movement of a part of a slope of rock detritus or soil, along a sliding surface where shear failure occurs
a geological phenomenon which includes a wide range of ground movement, such as rock falls, deep failure of slopes, and shallow debris flows, see flow
a large, sudden movement of loose rocks and soil
a movement of a mass of soil down a steep slope when the soil loses strength and can no longer support the weight of overlying soil or rocks
a movement of mass rock, debris, or earth down a slope
a movement of rock or debris down a slope along one or more distinct failure surfaces
a movement of surface material down a slope
a natural geologic-geomorphological phenomenon in which the soil and/or rock mass resting on top of a sliding surface starts to slowly or rapidly move downslope because of the pull of gravity
a rapid downslope movement of rock, snow, and ice
a similar massive movement of rock and soil
a general term used to describe the down-slope movement of soil, rock and organic materials under the influence of gravity. It also describes the landform that results.
In general, all varieties of slope movement, under the influence of gravity. More strictly refers to down-slope movement of rock and/or earth masses along one or several slide surfaces (in EM-DAT, « landslide » is a disaster subset of disaster type « slide »).
the movement of large amounts of soil, rocks, mud, and other debris downward and outward along a slope.
An abrupt movement of geological materials downhill in response to gravity. Landslides can be triggered by an earthquake or other natural causes. Undersea landslides can cause tsunamis, such as the one triggered by the 1929 Grand Banks earthquake.
The downslope movement of rock, soil, or mud.
Downslope movement of rock, soil, and mud.
An abrupt movement of soil and bedrock downhill in response to gravity. Landslides can be triggered by an earthquake or other natural causes. Undersea landslides can cause tsunamis.
A sudden or creeping movement of earth downslope.
A movement of earth down a steep slope.
Dislodged rock or earth that has slipped downhill under the influence of gravity and obstructs passage on a trail.
A sudden movement of rock and debris down a nonvertical slope.
A general term for a wide variety of processes and landforms involving the downslope movement, under gravity, of masses of soil and rock material.
Unconsolidated material that becomes unstable due to overloading or water saturation and slides down-slope.
The downslope movement of soil and/or rock.
A perceptible downhill sliding or falling of a mass of soil and rock lubricated by moisture or snow.
a sudden collapse of a large mass of hillside; the falling of masses of earth or rock
downslope movement of a mass of bedrock under the influence of gravity.
Downward movement of a slope and materials under the force of gravity.
The movement down the slope of a large mass of soil or rocks from a mountain or cliff. Often occurs after a torrential rain which soaks into the soil making it heavier and more mobile. Earthquakes and the undermining action of the sea are also causative agents.
a sliding down of a mass of soil or rock on a steep slope. [AHDOS
A mass of loosened rocks or earth that slides down a slope or hillside.
A general term covering the failure and rapid movement of rock masses downslope on the Earth's surface. Larva An insect, amphibian, or other pre-adult form of an animal that differs strongly from the adult form.
