Block slides are a type of translational slide that occur when large and relatively intact slabs of rock or earth are rapidly transported downslope. Most shallow landslides and flows occur during or up to several days after a heavy rainfall or rapid snowmelt event. Risk MAP delivers high-quality data, risk assessment tools and mitigation expertise to communities, tribes, and state and local agencies in their efforts to reduce the risks from natural hazards including floods, earthquakes, wildfire, and landslides. USGS interviews with eyewitnesses and analyses with dynamic landslide models indicate the landslides average speed was about 40 miles per hour. If enough water saturates the soil, it will not hold together on a slope. The Geological Survey inventoried 2,838 landslides throughout King County using new lidar data, raising awareness of a relatively common geologic hazard. Storefront (or) Table Top Charities - Where does your money go? Deep-seated landslides are those that fail below the rooting depth of trees and vegetation. Landslides are dangerous, unpredictable, and can occur rapidly. New volume estimates of the landslide using lidar-derived maps collected after the landslide reveal that, by the time the event had ended, the landslide had moved about 19 million tons of sand and till, and had covered approximately one-half square mile.

As our population expands into hilly and mountainous rural forests and agricultural lands, the need for mapping and understanding landslides and landslide hazards becomes increasingly urgent. The Oso Landslide occurred in an area of known landslide activity, but this time, the slide was much larger, traveled much further, and had greater destructive force than others previously experienced at the site. U.S. Landslide Inventory | U.S. Geological Survey Landslides take lives, destroy homes, businesses, and public buildings, interrupt transportation, undermine bridges, derail train cars, cover marine habitat and damage utilities.
