Idaho Geological Survey Landslides
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.

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.

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.

Therefore, α1α2α3 = 1 and β1 + β2 + β3 = 1. For graphical data presentation, β1, β2, β3 are the tools for interpreting the landslide geometry. The ternary diagram shown in Fig. 10 clearly demonstrates the differences between the three landslides observed. SL have smaller L , W, and H, and similar average β1 and β2.

Diagram of a rotational landslide. Parts Description; Crown: The undisturbed material uphill of the scarp. (i.e. the brown house at the top of the hill) Main Scarp: Steep slope at the upper edge of the landslide (at the head), caused by the movement of displaced material away from the undisturbed ground. The visible part of the slide surface.

Anatomy of a Landslide. By Kate Wong. Environment. Some landslides proceed at a snail's pace downslope, causing property damage. Others, however, gain a catastrophic momentum and often claim lives.
Landslide Morphology Landslide Mitigation
Landslides are a form of mass movement, a term used to describe any sort of gravity-induced movement of sediment down a slope. Mass movements can occur slowly over a period of years, or they can happen in a matter of minutes.

What is a 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.

Lesson 8: Landslides Hazards. Earthquakes are a major cause of landslides. Landslides occur when masses of rock, earth material, or debris flows move down a slope due to gravity. Landslides can.

The causes of landslides are usually related to instabilities in slopes. It is usually possible to identify one or more landslide causes and one landslide trigger. The difference between these two concepts is subtle but important.. the mechanics are essentially as per a real landslide. A: Diagram illustrating the resistance to, and causes of

This diagrams also reflects conditions of geology surrounding Vaiont Dam. If people dig into the base of a slope to create a road or a homesite, the slope may become unstable and move downhill. This is particularly dangerous when the underlying rock layers slope towards the area.

The calculation of the safety of a sliding block on a plane (a layered slide with preferential failure along pre-existing weaknesses) is shown below in figure 1. This calculation takes into account slope angle, friction, cohesion, and water content. Increasing water content and slope angle decreases the factor of safety.
