FAQ - Do I need to register my out of state business in Washington state? There are many more projects in progress with partners. Translational slides usually fail along geologic discontinuities such as faults, joints, bedding surfaces, or the contact between two rock types. Pore fluid pressure is the pressure that water exerts on all of the nearby grains. The addition of water to material on a slope can make landslides more common. The amount of friction between a deposit of rock or soil and the slope that it rests on plays a large role in when landslides happen. The addition of water can increase pore fluid pressure and separate grains. 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. Steve Bloom/The Olympian via AP 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 slide dammed the North Fork Stillaguamish River to a depth of as much as 25 feet, forming a temporary lake 2.5 miles long, which flooded houses and other structures in Steelhead Haven.

The neighborhood had historically been a slide area, with winter months routinely sending mud pouring onto beaches. Live video from KING-TV appeared to show crews rescuing a person and working to extinguish a fire just outside the home. Precipitation in the area during February and March 2014 was 150% to 200% of the long-term average, and likely contributed to slides initiation and mobility, the USGS analysis found. 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. The highway had flooded after heavy rains caused the Skookumchuck River to rise about its northern banks. This cut the river bed back to near its pre-landslide elevation and effectively drained the remaining excess water by the middle of May. Material from The Seattle Times archives was used in this story. Below is a summary of key USGS projects underway. HomePrograms and ServicesGeologyGeologic Hazards.

Original Story -- Release Date:MARCH 16, 2015, One Year Later The Oso Landslide in Washington. Another massive slide in 2013 on Whidbey Island sent a 1,000-foot-wide swath off a hillside cliff into the Ledgewood Beach development on the west side of the island. Today in Washington, D.C., members of the USGS Landslides Program and interagency partners from around the country briefed congressional staff members and key stakeholders in a series of presentations called, Gravity Never Sleeps: Landslide Risk Across the Country. The presentations provided information on landslide causes and impacts, current and ongoing research, and mitigation efforts to protect Americas communities. Separation of structures from their foundation; movement of soil away from foundations. It is also referred to as the SR530 Landslide, as named by Snohomish County and Washington State. It also caused 43 fatalities in the community of Steelhead Haven near Oso, Washington. The leading edge of the wet debris avalanche probably acquired additional water as it crossed the North Fork Stillaguamish River, ultimately transforming into a water-saturated debris flow. The water may be deeper than it appears.

Washington has seen many large and lethal landslides.. Sticking windows or doors; new and (or) growing cracks in walls, ceilings, or foundations. A landslide is the movement of rock, soil and debris down a hillside or slope. Landslides occur in all 50 states and U.S. territories, and cause $1-2 billion in damages and more than 25 fatalities on average each year. Landslides exist throughout Washington State and can be triggered in many ways. The direct cost of landslide damage includes the repair of roads and property and the loss of life. The 2009 Nile landslide blocked the Naches River and covered State Route 410. Following the landslide inventory methods first produced by the Oregon Department of Geology and Mineral Industries, the Washington Geological Survey has developed their own landslide inventory protocol for Washington State. Washington Gov. Slowly developing, widening cracks appear on the ground or on paved areas. Leave the area immediately if it is safe to do so! Debris flows are liquefied slurries of rock, water and mud that can travel great distances at high speeds, entraining nearly all objects in their paths. Reston, VA 20192 Snow and rain forced the closure of parts of Washington state's two major highways Interstate 90 and Interstate 5 with flooding that also swamped roads throughout Western Washington and Oregon. The road is closed both directions from MP 3.08 near Elma Hicklan Rd to MP 9.7 near Hurley Waldrip Rd beginning at 12:29 pm on Jan. 6, 2022 until further notice. In addition to lidar, the geologists used aerial imagery, field observations, and previous mapping to identify landslides. Build channels or deflection walls to direct the flow around buildings. Such a system would enhance the USGS ability to respond to landslide crises such as the Oso Landslide. Signs of a potential landslide should be reported to your county Emergency Manager so that the area can be properly evaluated. Lateral spreads occur on very low-angle slopes toward a free face such as a cliff or embankment. Your county geologist or county planning department may have specific information on areas vulnerable to landslides. Erosion by rivers, glaciers, or ocean waves that create over-steepened slopes. Tidal flooding of homes and businesses also affected towns including Edison and University Place. They are usually composed of relatively loose or unconsolidated material. USGS scientists are conducting aerial overflights to collect photographs and monitor river channel evolution through the landslide. Today's 5-year-olds will likely live . 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? Be aware of your surroundings, Hanell said. The Landslide Compilation contains landslides from the following sources: (1) Landslides that are mapped within 1:24,000-scale geologic mapping (not statewide) and our statewide 1:100,000-scale geologic map compilation; (2) a miscellaneous compilation of pre-existing landslide data from several sources, including the Washington Geological . Washington is one of the most landslide-prone states in the country, with hundreds to thousands of events each year. This and other processes decrease strength and can promote landslides. A key example of this collaboration is outlined in a story the USGS ran in March of 2015 on the one-year anniversary of the Oso landslide that occurred in northwest Washington. In southwestern Washington's Lewis County, a 20-mile (32-kilometer) stretch of Interstate 5 had been closed in both directions south of Chehalis because of flooding from the Chehalis River. A percentage of the landslides are field-checked and all landslide polygons are reviewed by a licensed geologist. Other researchers have identified the ages of some of these landslides, which range from 500- to 6,000-years old, but there is still a lack of understanding for the overall recurrence time frame for these types of landslides. USGS research on the North Fork Stillaguamish River is aimed at identifying potential impacts to the aquatic ecosystem and changes to flood risk along the river corridor including newly reconstructed stretches of State Route 530 and downstream bridges. The Washington State Department of Transportation annually budgets for about $15 million in landslide cleanup for highways alone. Broken or leaking utilities, such as water, septic, or sewer lines.
