Mudslides or you can call them landslides are very dangerous. They can accompany heavy rains or follow droughts, earthquakes, or volcanic eruptions. Mudslides develop when water rapidly accumulates in the ground and results in a surge of water-saturated rock, earth, and debris.
Near populated areas, landslides present major hazards to people and property. Landslides cause an estimated 25 to 50 deaths and $3.5 billion in damage each year in the United States. Landslides have three major causes: geology, morphology, and human activity.
There are many ways to describe a landslide. The nature of a landslide's movement and the type of material involved are two of the most common.
Volcanic landslides, also called lahars, are among the most devastating type of landslides.
Land. Mudslides move at more than 20 mph and contain not just mud, but rocks, trees and other debris.
Landslides are caused by disturbances in the natural stability of a slope. Mudslides usually start on steep slopes and can be activated by natural disasters. Areas where wildfires or human modification of the land have destroyed vegetation on slopes are particularly vulnerable to landslides during and after heavy rains.
Every year, mudslides and landslides cause more than $2 billion in damages to homes and businesses across the United States, according to the Federal Emergency Management Agency (FEMA).
Similar conditions can also happen in areas experiencing extensive dry or drought conditions.
