Landslides are downward or outward movements of soil, rock, or vegetation under the influence of gravity. There are several types of landslides including rotational, translational, rock fall, rock toppling, lateral spreading, and debris flows. Landslides are caused by both natural factors like heavy rainfall, earthquakes, volcanic activity, and human factors like construction. Landslides can cause physical damage, casualties, flooding, loss of infrastructure and property, and decreased agricultural productivity and property values. Signs of landslide risks include steep slopes, cracks in the ground, tilted trees or structures, and changes in groundwater levels.
