Landslides are caused by various factors, which are mentioned below: Deforestation is also one of the main reasons for landslides because trees, plants, etc., keep the soil particles compact and due to deforestation, the mountain slopes lose their protective layers because of which the water of the rain flows with unimpeded speed on these slopes. The movement of the rocks or debris etc., on a slope downwards, is called a landslide. Consequently, the further established vulnerability planning and risk assessments, the more of a comprehensive span of resiliency preparedness. In the event of a wet eruption, the soil will begin to move downhill, causing a landslide. A wide range of ground motions, such as rockfalls, deep-seated slope failures, mudflows, and debris flows, can all contribute to mass wasting. It leads to the diversion of river water, which can cause floods as well. When earthquakes strike places with steep slopes, the soil often slips, resulting in landslides. Likewise, susceptibility maps provide a better understanding of how landslide hazard and risk can be assessed. Though landslides often have negative impacts on man, landslides are good for the environment.
