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 ...
Whilst the example given in Figures A and B is clearly an artificial situation, the mechanics are essentially as per a real landslide. A: Diagram illustrating the resistance to, and causes of, movement in a slope system consisting of an unstable block B: Diagram illustrating the resistance to, and causes of, movement in a slope system ...
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 ...

Sketch diagram showing the aerial photograph of Pat Heung in 1989 in Hong Kong. It shows how the yellow current landslides were identified within the red study area on the slopes of the natural terrain using interpretation techniques. A total of seven current landslides were identified.

Using laser scans and GPS cameras, accurate down to one inch, the U.S. Geological Survey has so far mapped more than 600 landslides caused by Hurricane Helene. Geologists map hundreds of ...
The application of vegetation to increase the slope stability against erosion and landslide is a form of bioengineering that is widely used in areas where the landslide depth is shallow. Vegetation increases the stability of the slope mechanically, by reinforcing the soils through plant roots, which stabilize the upper part of the soil.
