"Mudslides occur in all 50 U.S. states and can happen at any time – with or without rainfall," said Lynn Highland, a geographer at the USGS National Landslide Center. ...


Landslides are caused by disturbances in the natural stability of a slope. 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 ...


Mudslides occur in areas where the land has been destabilized by the removal of vegetation, often as a result of wildfires or human activities. Mudslides tend to occur when there is a steep slope and may reoccur in the same location. The most commonly affected states in the United States include California, Oregon, Washington, Alaska and Hawaii.

Mudslides differ from landslides in that landslides are composed of rocks, soil and debris that has come loose from a steep slope and tumble down. Mudslides tend to flow down a channel in a hillside or mountainside. Most mudslides are the result of heavy rain which causes water to build up in the soil at an overwhelming rate.


A large mudslide can have multiple shelves. Mudslides often occur in areas with steep slopes or at the bottom of slopes or canyons. Mountainous areas that have been altered to build homes and roads are often prone to mudslides. When human actions or natural events, such as wildfires, increase erosion in an area, mudslides can be a natural result.


Catastrophic mudslides have swallowed homes and killed at least 15 people in Southern California. A variety of unique factors have made them especially calamitous.

Where do they occur? Mudslides typically occur in areas with steep hillsides, gullies and other narrow channels that make it easy for rain, mud and debris to flow through -- much like the terrain ...
