Landslides occur when the slope (or a portion of it) undergoes some processes that change its condition from stable to unstable. This is essentially due to a decrease in the shear strength of the slope material, an increase in the shear stress borne by the material, or a combination of the two.
Jul 1, 2024 · 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.
5 days ago · The movement of the rocks or debris etc., on a slope downwards, is called a landslide. It is a type of "mass wasting ", which refers to the movement of any mass, soil, or rocks under the influence of gravity. It is one of the natural hazards and can be a disaster if the damages occur in large amounts.
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.
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.
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.
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.
Mar 18, 2023 · The database covers landslide vulnerable regions in 17 states and 02 UTs of India in the Himalayas and Western Ghats. The database includes three types of landslide inventory - seasonal, event-based and route-wise for the 1998-2022 period.
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 are one of the most pervasive hazards in the world, resulting in more fatalities and economic damage than is generally recognized. Every year they block roads, damage infrastructure, and cause thousands of fatalities.
