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 ...
Some landslides are complex in the sense that they feature different movement types in different portions of the moving body, or they evolve from one movement type to another over time. For example, a landslide can initiate as a rock fall or topple and then, as the blocks disintegrate upon the impact, transform into a debris slide or flow.
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 ...
Articles relating to landslides, several forms of mass wasting that may include a wide range of ground movements, such as rockfalls, shallow or deep-seated slope failures, mudflows, and debris flows. Landslides occur in a variety of environments, characterized by either steep or gentle slope gradients, from mountain ranges to coastal cliffs or ...
Sudden slumps usually occur after earthquakes or heavy continuing rains, and can stabilize within a few hours. Most slumps develop over comparatively longer periods, taking months or years to reach stability. An example of a slow-moving slump is the Swift Creek Landslide, a deep-seated rotational slump located on Sumas Mountain, Washington.
A dozen homes torn apart by earth movement on Southern California's Palos Verdes Peninsula during the weekend were likely to fall into an adjacent canyon, an official said. The homes in the Los ...
Large landslides from volcanoes often bury valleys with tens to hundreds of metres of rock debris, forming a chaotic landscape marked by dozens of small hills and closed depressions. If the landslide deposit is thick enough, it may dam streams to form lakes. These lakes may eventually drain catastrophically to create floods and lahars ...
A large landslide entered Sullorsuaq Strait, generating a megatsunami which struck Alluttoq Island, where it had a run-up height of 45 to 70 metres (148 to 230 ft). [15] ~2800 BCE Zion Canyon, Utah, US: 0.286 km 3: Landslide created the currently level floor of Zion Canyon inside Zion National Park. [21] ~1920 BCE Jishi Gorge, Qinghai Province ...
