Landslides

- Text adapted from USGS Hazards: Landslides page

Landslides are termed the sleeper of all the geologic hazards. Though incited by snowmelt, rain, poor excavation, or earthquakes, they sometimes startle the unsuspecting homeowner with the ferocity of their rapid movement, or the slow stretching of the once peaceful terrain.

Landslides constitute a major geologic hazard because they are widespread, occurring in all 50 States, and cause $1-2 billion in damages and more than 25 fatalities on average each year. Landslides pose serious threats to highways and structures that support fisheries, tourism, timber harvesting, mining, and energy production, as well as general transportation. Landslides commonly occur with other major natural disasters, such as earthquakes and floods. They exacerbate relief and reconstruction efforts, and expanded development and other land use has increased the incidence of landslide disasters.
