Landslides are geological events where a mass of earth, rock, or debris moves down a slope, driven by gravity.
They can occur suddenly with little warning and are often triggered by factors like heavy rainfall, earthquakes, volcanic activity, or human-induced changes to the land, such as deforestation or construction. Landslides vary in size and speed, from slow soil creep to rapid and destructive slides. They pose significant risks, including property damage, road blockages, and threats to human safety. The impact of a landslide depends on its size, material involved, and the area's vulnerability. Efforts to predict and mitigate landslide risks involve understanding local geology and implementing appropriate land-use policies.
