Listen to a battery-operated radio or television for emergency information. The information on this webpage is also contained in two factsheets: Landslide Hazards in Washington State and What Are Landslides And How Do They Occur? Movement is accompanied by cracking of the ground. Know which areas are safe and how to reach them in an emergency. A major difference between the types of landslides is their depth and the amount of water they contain. SR 109 closed due to landslide (City of Hoquiam). Mapping shows a slow-moving landslide now blamed for cracked pavement on SR 109 and could lead to the highway possibly collapsing. While gravity is the primary reason for a landslide, there can be other contributing factors, including: Commonly, landslides occur on slopes and in areas where they have taken place before, as well as in areas where they have not been previously documented. The Legislature directed the Department of Natural Resources to identify and map landslides throughout Washington and disseminate the information to the public. This extra weight adds to the gravitational force. She won the jackpot. Outside walls, walks or stairs begin pulling away from the building. The 2009 Nile landslide blocked the Naches River and covered State Route 410.

Boeing employee bought lottery ticket because it was at $747M, a nod to the aircraft. USGS, working with the University of Washington, University of California, Los Angeles, NOAA, and other partners, published findings that revealed that the time of year in which the seasonal total precipitation had occurred was relevant to triggering the landslide -- heavy precipitation occurred toward the end of the rainy season when the ground was already nearly saturated. It is important to note that the type or size of landslide is largely irrelevant if you happen to be the one in harm's way. Below is a summary of key USGS projects underway. Erosion by rivers, glaciers, or ocean waves that create over-steepened slopes. BELLINGHAM, Wash. At least one person was missing and presumed dead as snow turned to rain and deluged the Pacific Northwest on Friday, causing flooding, landslides and avalanche danger in the mountains. Slowly developing, widening cracks appear on the ground or on paved areas. Did Scientists Expect the Oso Landslide to Happen? These spiders, which were placed on and near the landslide, contained high-precision GPS units for detecting landslide movement as well as geophones for detecting small vibrations. This and other processes decrease strength and can promote landslides. The goal of USGS landslide science is to help answer questions such as where, when, and how oftenlandslides occur and how fast and far they might move. In the immediate aftermath of the SR530 Landslide, the USGS supported first responders and decision-makers as a key member of the collaborative effort to monitor the stability of the landslide deposit and the associated impoundment of the North Fork Stillaguamish River during rescue operations. Research by the U.S. Geological Survey indicates that the landslides average speed was about 40 mph, with maximum speeds likely even higher. But unquestioned is the regularity with which homes and lives are lost to landslides in Washington. This buoyant force weakens the material and is also why your feet sink into beach sand after a wave washes over and adds water. Some homes flooded and at least one apartment building was evacuated, KIRO-TV reported. The Washington Geological Survey works to increase public and scientific understanding of landslide hazards in Washington State. Small landslides, such as those that may affect roads during rain events, were not part of this inventory because they are not typically visible in lidar maps. PO Box 40220 The addition of water increases weight and reduces friction. South . Falls and topples are usually rapid, downward movement of large pieces of rock or debris.

Alluvial fans are typically located on valley floors at the base of steep slopes where water transports sediment onto the fan surface. Excess weight, from accumulation of rain or snow, from stockpiling of rock or ore, from waste piles, or from manmade structures, may stress weak slopes to failure.
