Landslides FAQs - 13 Found
Landslides can and do occur in every state and territory of the U.S.; however, the type, severity and frequency of landslide activity varies from place to place, depending on the terrain, geology, and climate. Major storms have caused major or widespread landslides in Washington state, Oregon, California, Colorado, Idaho, Hawaii, Virginia, Ohio, Pennsylvania, Tennessee, North Carolina, Puerto Rico, and elsewhere. Rapid snowmelt has caused landslides in Colorado, Nevada, Utah, Wyoming, and Washington State, as well as other mountainous states. The Appalachian Mountains, the Rocky Mountains, the Pacific Coastal Ranges, and some parts of Alaska and Hawaii have moderate to severe landslide problems. Any area of weak or fractured materials resting on a steep slope can and will likely experience landslides.
Although the physical causes of many landslides cannot be removed, geologic investigations, good engineering practices, and effective enforcement of land-use management regulations can reduce landslide hazards.
