2 days ago · landslide, the movement downslope of a mass of rock, debris, earth, or soil (soil being a mixture of earth and debris). 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.
A landslide is defined as the movement of a mass of rock, debris, or earth down a slope. Landslides are a type of "mass wasting," which denotes any down-slope movement of soil and rock under the direct influence of gravity. The term "landslide" encompasses five modes of slope movement: falls, topples, slides, spreads, and flows.
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 .
Animation of a landslide in San Mateo County, California. 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]
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.

Landslides occur in all 50 states and territories, and they affect lives, property, infrastructure, and the environment. 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.
Landslides. Landslides are more widespread than any other geological event, and can occur anywhere in the world. They occur when large masses of soil, rocks or debris move down a slope due to a natural phenomenon or human activity. Mudslides or debris flows are also a common type of fast-moving landslide. Landslides can accompany heavy rains or ...
The term “landslide” describes a wide variety of processes that result in the downward and outward movement of slope-forming materials including rock, soil, artificial fill, or a combination of these. The materials may move by falling, toppling, sliding, spreading, or flowing.
Landslides occur when masses of rock, earth material, or debris flows move down a slope due to gravity. Landslides can occur on any terrain if the conditions are right, and cause significant...
Landslides @ NASA is a project of NASA's Global Precipitation Measurement Mission (GPM) which use satellite data and citizen science data to model and inventory landslides around the world. We are based at NASA Goddard Space Flight Center ( GSFC ). Learn more about our publications and projects on the Resources page.
