In the United States, landslides and mudslides result in 25 to 50 deaths each year. The health hazards associated with landslides and mudslides are rapidly moving water and debris that can lead to trauma, broken electrical, water, gas and sewage lines that can result in injury or illness; and disrupted roadways and railways that can endanger motorists and disrupt transport and access to health care.
Some areas are more likely to experience landslides or mudslides, including areas where wildfires or construction have destroyed vegetation, steep slopes and areas at the bottom of slopes or canyons, and slopes that have been altered for construction of buildings and roads where surface runoff is directed.
Landslides are caused by disturbances in the natural stability of a slope. They can happen after heavy rains, droughts, earthquakes or volcanic eruptions, fire and by human modification of land. They can flow rapidly, striking with little or no warning at avalanche speeds. They also can travel several miles from their source, growing in size as they pick up trees, boulders, cars and other materials. This course describes the types of landslides/mudslides and areas that are likely to experience them as well as other natural hazards.
