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 ...
Mudslides and landslides can cause extensive property damage and even be fatal. Here's a look at the causes of and differences between them. Most common causes of mudslides and landslides [Video]
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.
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 ...
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.
