An official website of the United States government. A .gov website belongs to an official government organization in the United States. 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. These organizations include Snohomish County; the Washington State Emergency Management Division; the Federal Emergency Management Agency; the Washington State Department of Natural Resources; the Washington State Department of Transportation; NOAAs National Weather Service; the U.S. Army Corps of Engineers; the Stillaguamish Tribe of Indians; and the USGS. When there is a lot of water and the pore fluid pressure is high, the water buoys up the grains and forces them apart. The Oso landslide in Snohomish County on March 22, 2014, killed 43 people and destroyed 49 homes and other structures when an unstable hill . also called a debris flow, is a type of fast-moving landslide that follows a . The opinions expressed in reader comments are those of the author only and do not reflect the opinions of The Seattle Times. 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. Reggie Brown, of Centralia, carries his daughter, Ocean, 4, on his shoulders as he walks through the floodwaters on Highway 507 with his wife, Jonell Brown, on Friday in Centralia, Wash. 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. Landslides are complex, often moving in numerous different ways, from small shallow slumps and rock topples to deep-seated landslides. The Oso landslide response involved many federal, tribal, state, and local agencies, as well as the private sector. Although there is still much to learn about the Oso landslide, USGS and other scientists have unraveled invaluable scientific information that is shedding light on how and why such landslides happen. Bulging ground appears at the base of a slope. Its unknown how long SR 109 will be closed because the hillside is still unstable. By releasing this data and making people aware of landslide danger, we hope to lower the risk to hundreds of thousands of King County residents..

There are two major types of landslides, Hanell explains. The force of rocks, soil, or other debris moving down a slope can devastate anything in its path. In Seattle's Magnolia neighborhood, firefighters responded to a home that slid down a hillside. That amount of material would cover about 600 football fields 10 feet deep. Water is not only heavy, increasing the driving force of a slope, but it pushes soil grains apart, insinuating its way between the tiniest particles. A landslide generally refers to the downhill movement of rock, soil, or debris. Response to the Oso Landslide has involved many federal, tribal, state, and local agencies, as well as the private sector. The addition of water can decrease friction, decrease strength, and increase the weight of the material. USGS scientists develop tools and producemaps of areas susceptible to landslides and identify what kinds of conditions will most likely lead to such events.

The addition of water increases weight and reduces friction. City leaders are concerned about the weight of snow on buildings and homes, KCPQ-TV reported. Lahars are debris flows that originate on volcanoes. 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. Rotational slides often occur because the internal strength of the material is overcome by its own weight. Mudflow is covered by flood insurance policies from the National Flood Insurance Program. And staffers scour news and government agency reports, even social media . Rockfalls and topples are common in Washingtons mountain highways. As the Northwests rainy season takes its usual toll, the Northwest Insurance Council, a trade group, once again is posting the warning on its website that standard homeowners, renters and business insurance policies do not include coverage for landslides. The landslides high mobility was likely due to several contributing factors, including the soils initial porosity and water content from rainfall in the months prior. If enough water saturates the soil, it will not hold together on a slope. A .gov website belongs to an official government organization in the United States. A lock () or https:// means youve safely connected to the .gov website. Also check out Ear to the Ground, published by the Department of Natural Resources.

Sunrise Beach Dr. NW in Gig Harbor is closed in the 10210 block due to a landslide. Debris flows usually occur in steep gullies, move very rapidly, and can travel for many miles. Landslides are dangerous and unpredictable. This event is commonly named the Oso Landslide in many official reports. Check for damaged utility lines. Check for injured and trapped persons near the slide area. The Washington Department of Transportation routinely budgets $15 million a year for cleanup of landslides on highways. USGS research indicates that the landslides average speed was about 40 miles per hour, with maximum speeds likely even higher. The addition of water to material on a slope can make landslides more common. Plan at least two evacuation routes since roads may become blocked or closed. Washington is one of the most landslide-prone states in the country, with hundreds to thousands of events each year. The goal of USGS landslide science is to help answer questions such as where, when, and how often landslides occur and how fast and far they might move. The direct cost of landslide damage includes the repair of roads and property and the loss of life. Consult a professional geotechnical expert for advice on corrective measures you can take. 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. In addition to lidar, the geologists used aerial imagery, field observations, and previous mapping to identify landslides. The compilation is updated regularly throughout the year and includes reported landslides since 2015. When there is little water and low pore fluid pressure, most grains are touching and the material is relatively strong. Report any damage to the utility company. 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. 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 landslide inventory for King County also includes an inventory of alluvial fans, fan-shaped features created by streams, floods or debris flows that leave sediment behind. Dont add water to steep slopes. Get a ground assessment of your property. This buoyant force weakens the material and is also why your feet sink into beach sand after a wave washes over and adds water. Now is the time when the risk is accentuated, as abundant rains saturate soils. Residents living in. chevron_right Geothermal Resources. This station is part of Cox Media Group Television. Landslides can occur on gentle to steep slopes but they are most common on steep slopes. With heavy snow continuing in Washington's mountains, the . Learn more about Washington state projects. A man trapped in the home's basement was extricated, according to the Seattle Fire Department. The term landslide can also refer to the deposit that is created by a landslide event. Deep-seated landslides can also occur at any time. The highway had flooded after heavy rains caused the Skookumchuck River to rise about its northern banks. Understanding how and why these landslides move help geologists develop mitigation techniques and determine future hazards for roads, houses, infrastructure, and human life. SR 108 at MP 5 is closed in both directions for the second time today for another landslide. Deep-seated landslides can occur at any time. For more information,watch a videoabout USGSlandslide science, and visit theUSGS LandslideHazards Program website. This accelerated movement was caused by the liquefaction of the saturated soils underneath the landslide, allowing the moving soil to quickly hydroplane across the river valley. Scientists are collecting continuous data from those gages in order to analyze downstream movement of sediment and identify possible regions of accumulation. An incident of this magnitude was not expected based on previous studies of past events in the area as well as comparison with landslides worldwide of this height, volume and type. 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. 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 . A landslide usually occurs because the internal strength of the rock, soil, or sediment becomes less than the force of gravity. The most in-depth studies from the USGS indicate that slope failure occurred in two stages over the course of about one minute. The highway had flooded after heavy rains caused the Skookumchuck River to rise about its northern banks. A large landslide occurred in northwest Washington on March 22, 2014, leading to tragic loss of life and destruction of property.

Kolisch Road E (in Carbonado) is closed at the 32910 block due to a landslide. The USGS presently operates eight streamgages along the Stillaguamish River, with two being permanent and six as rapid-deployment gages. Landslides take lives, destroy homes, businesses, and public buildings, interrupt transportation, undermine bridges, derail train cars, cover marine habitat and damage utilities. This cut the river bed back to near its pre-landslide elevation and effectively drained the remaining excess water by the middle of May. In northwest Washington, snow fell in Bellingham while roadways flooded throughout Whatcom County. This is because water adds significant weight to the slope as it seeps into the ground and becomes groundwater. The Oso landslide in Snohomish County on March 22, 2014, killed 43 people and destroyed 49 homes and other structures when an unstable hill collapsed, sending mud and debris south across the North Fork of the Stillaguamish River and Highway 530. They move out or down along a planar surface with little tilting, and can travel great distances. Alluvial fans are typically located on valley floors at the base of steep slopes where water transports sediment onto the fan surface. The landslides are delineated with polygon and line features as well as given 17 unique attributes, including a movement type, a movement azimuth, and a confidence rating (how certain the geologist is that the feature is a landslide). Official websites use .gov On a quiet Saturday in March 22, 2014, the small, tight-knit community of Oso, Wash. was shaken with one of the deadliest landslides in our nations history. 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. These long-lived features can be partially or entirely reactivated for a variety of reasons. Shortly after the slide, USGS scientists identified and published a paper describing the North Fork Stillaguamish River valley and the geologic evidence they had uncovered showing the occurrence of past landslides, some of which traveled in a similar pattern to that of the 2014 landslide. Washington Gov. That amount of material would cover approximately 700 football fields 10 feet deep. Listen to a battery-operated radio or television for emergency information. Landslides nearly always move down a slope. Landslides are one of the most common and devastating natural hazards in the Pacific Northwest and the damage they cause is almost never covered by insurance, warns the state Department of Natural Resources in its Homeowners Guide to Landslides, at st.news/slide. Landslides are dangerous, unpredictable, and can occur rapidly. The Tribal government declared a state of emergency for the region. Back-tilting may occur near the scarp of the landslide and there is often a toe of displaced material. Forecasters say the rains should subside over the weekend but landslides will continue to be a risk into Saturday as soils remain saturated.
