6 days ago · Landslide, the movement downslope of a mass of rock, debris, earth, or soil. Landslides occur when gravitational and other types of shear stresses within a slope exceed the shear strength (resistance to shearing) of the materials that form the slope.
Landslides, also known as landslips, [1] [2] [3] are several forms of mass wasting that may include a wide range of ground movements, such as rockfalls, mudflows, shallow or deep-seated slope failures and debris flows. [4] .
Apr 26, 2024 · A landslide is the movement of rock, earth, or debris down a sloped section of land. Landslides are caused by rain, earthquakes, volcanoes, or other factors that make the slope unstable. Geologists, scientists who study the physical formations of Earth, sometimes describe landslides as one type of mass wasting.
A 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:

Sep 28, 2022 · Introduction. 1.1 Concept of landslides. Landslides, one of the catastrophic events on earth, can cause extensive impacts, for instance, loss of human life, destruction of infrastructures and residential developments, and damage to cultural and natural heritage [ 1 ].
The toe of the landslide marks the end of the moving material. The toe marks the runout, or maximum distance traveled, of the landslide. In rotational landslides, the toe is often a large, disturbed mound of geologic material, forming as the landslide moves past its original rupture surface.
Nov 15, 2008 · This handbook helps homeowners, community and emergency managers, and decisionmakers to take the positive step of encouraging awareness of available options and recourse in regard to landslide hazard. We provide a list of references, available in print or on the World Wide Web (Internet), that can be used for further knowledge about landslides.
Jun 27, 2024 · A landslide is broadly defined as a sudden mass movement of substrate downhill and occurs on sloping terrain. Landslides can be localized slumps several square meters in size or so large that they are visible from space. Why are landslides important to you?
Landslides are the downslope movement of earth materials (rock, debris, and soil) at rates that range from inches per year to tens of miles per hour. Some landslides can move faster than a person can run. Landslides can happen with no notice or can take place over a period of days, weeks, or longer. Sources/Usage: Public Domain.
