They commonly occur along an existing plane of weakness. The main modes are translational (along a flat plane) and rotational (along a concave surface). Slides may be File Size: KB. Landslides constitute a major geologic hazard because they are widespread, occur in all 50 states and U.S. territories, and cause $ billion in damages and more than 25 fatalities on average each year. Expansion of urban and recreational developments into hillside areas leads to more people that are threatened by landslides each year.
A new U.S. Geological Survey map of Puerto Rico shows the relative risks of landslides due to the kind of intense rainfall brought on by hurricanes. It identifies 20% of the island as at high risk, 9% at very high risk, and 1% at extremely high risk of landslides under those conditions. Washington is one of the most landslide-prone states in the country, with hundreds to thousands of events each year. The direct cost of landslide damage includes the repair of roads and property and the loss of life. Indirect costs, such as loss of property value and tax revenue, and environmental effects. The history of real-time monitoring for potential landslides from water and debris flows. Monitoring hillslopes with the goal of eventually establishing an early warning system for debris flows. Landslides often occur in response to heavy or prolonged rainfall. On hillsides, gravity is constantly. "Major landslides triggered by the magnitude Great Alaska earthquake responded to, but were not reactivated by, the magnitude Anchorage earthquake that took place 30 November , researchers concluded in a new study published in Seismological Research Letters."

Heavy precipitation near the end of December resulted in widespread flooding and localized landsliding in the western states of California, Oregon, Washington, Nevada, and Idaho. Many of the landslides occurred in the Puget Lowland of western Washington (fig. Landslides and landslide hazards in Washington State due to February , storm /Author: Edwin L. Harp and Geological Survey (U.S.). Washington State faces many geologic hazards, from tsunamis and landslides, to volcanoes and earthquakes. This page details all of these hazards and what the Washington Division of Geology does to serve the public interest. The model is intended for use as a shallow landslide forecasting tool for use by city and county emergency managers. The map is not predictive, nor does it forecast the potential for deep-seated landslides. If a landslide occurs, evacuate the area and contact your local emergency management agency.
