How do rockslides occur
WebLandslides occur when masses of rock, earth, or debris move down a slope. Debris flows, also known as mudslides, are a common type of fast-moving landslide that tends to flow in channels. [1] Mudslides develop when water rapidly accumulates in the ground and results in a surge of water-saturated rock, earth, and debris. WebSep 17, 2024 · Long considered as a secondary effect of earthquakes, landslides triggered by earthquakes, mainly rock falls, disrupted soil slides and rock slides, mudflows and rock avalanches, can be responsible for a significant part of the damage associated with earthquakes [1].
