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.

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.

Figure 10.4.1 10.4. 1: Approximate extent of Markagunt Gravity slide. Markagunt Gravity Slide: About 21-22 million years ago, one of the biggest land-based landslides yet discovered in the geologic record displaced more than 1,700 cu km (408 cu mi) of material in one relatively fast event. Evidence for this slide includes breccia.

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
Landslide Hazards Geohazards (U.S. National Park Service)
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.

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 com-bination of these. The materials may move by falling, toppling, sliding, spreading, or flowing.

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.

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.

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.

Slides. Figure 3. These schematics illustrate the major types of landslide movement. Although many types of mass movements are included in the general term "landslide," the more restrictive use of the term refers only to mass movements, where there is a distinct zone of weakness that separates the slide material from more stable underlying material.
