A landslide is the movement of a large amount of debris, rock, or earth down a slope in certain land areas. Landslides are caused by heavy rains, volcanoes, earthquakes, and other similar factors that make the slope unstable. It is a common phenomenon in most hilly areas, especially during the monsoon season.
