Landslides

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.

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.

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.

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.

Mass Movement Geography

landslide, the movement downslope of a mass of rock, debris, earth, or soil (soil being a mixture of earth and debris).

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.

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.

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.

(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.

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.

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.

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.
