What is the force acting on the slope of a landslide?

Colorado Geological Survey is the primary State agency for providing information and maps on geologic hazards such as landslides, mud/debris flows, and rockfall. Additionally, the Colorado Landslide Hazard Mitigation Plan and the Colorado Landslide Viewer are useful tools addressing these hazards locally. coloradogeologicalsurvey.org.

What are the hazards of Colorado?

Landslides, mud flows, debris flows, and rockfalls are among many geologic and soil hazards that impact Colorado. Colorado Geological Survey, photo by Division of Reclamation and Mining. Landslides are the downward and outward movement of slopes composed of natural rock, soils, artificial fills, or combinations thereof.

When do rock falls occur?

Rockfalls are the fastest type of landslide and occur most frequently in mountains or other steep areas during early spring when there is abundant moisture and repeated freezing and thawing.

How do landslides move?

Landslides move by falling, sliding, and flowing along surfaces marked by differences in soil or rock characteristics. A landslide is the result of a decrease in resisting forces that hold the earth mass in place and/or an increase in the driving forces that facilitate its movement.

What is mud flow?

Debris and mud flows are combinations of fast-moving water and great volumes of sediment and debris that surge down a slope with tremendous force. They are similar to flash floods and can occur suddenly without time for adequate warning.
