Any commuter on the Sounder trains traveling at the base of bluffs along the shore of Puget Sound is all too familiar with these sorts of landslides, which disrupt service on the mud-piled tracks. The powerful slide shoved one home at the bottom of the cliff about 200 feet into the water, and took out nearly 400 feet of Driftwood Way, the road to the shoreline. USGS scientists have been studying this event since the landslide occurred. Report the problem immediately to your county Emergency Manager. The hillsides history of slides dates back more than 60 years and some experts said they were shocked when homebuilding was permitted after a big slide in 2006. Washington state landslide Downed power lines and parts of a destroyed house can be seen in the debris blocking the road near Oso on March 23. In both western Washington state and British Columbia, entire communities were engulfed by floodwaters, which entered homes and businesses early this week, displacing thousands of people.. DNRs Geologic Information Portal, searchable by address, is one place to start. USGS scientists continue to study the site to gain new insights that only such a significant, though unfortunate, event can reveal. Please visit our Geologic Information Portal and Geologic Hazard Maps page for the most up-to-date listing of all of our hazard maps. Indirect costs, such as loss of property value and tax revenue, and environmental effects, such as the degradation of water quality, can exceed direct costs. If the landslide had behaved in the expected range, it would have likely blocked the river and possibly destroyed some houses, which may have caused casualties. Leave the area immediately if it is safe to do so! This cut the river bed back to near its pre-landslide elevation and effectively drained the remaining excess water by the middle of May. Report any damage to the utility company. Landslides are complex, often moving in numerous different ways, from small shallow slumps and rock topples to deep-seated landslides. Dont add water to steep slopes. Lahar on Mount St Helens. Landslide debris covered about 40 homes and other structures as well as nearly a mile of State Route 530. USGS research indicates that the landslide traveled exceptionally far, crossing the entire one-half-mile wide river valley. The neighborhood had historically been a slide area, with winter months routinely sending mud pouring onto beaches. Translational slides usually fail along geologic discontinuities such as faults, joints, bedding surfaces, or the contact between two rock types.

Using helicopters, the USGS deployed three portable instrument packages called spiders, specifically developed for monitoring active volcanoes and landslides. Washington has seen many large and lethal landslides. Ground failures that result in landslides occur when gravity overcomes the strength of a slope. The Legislature directed the Department of Natural Resources to identify and map landslides throughout Washington and disseminate the information to the public. menu. A reminder to drivers: do not drive through flooded roadways if they are not already blocked off. Most shallow landslides and flows occur during or up to several days after a heavy rainfall or rapid snowmelt event. More than 31,000 Washington state electrical customers remained without power on Tuesday. Also check out Ear to the Ground, published by the Department of Natural Resources. But they can be set off again by human activities, such as excavating at the base of a slope, or adding water to it, Hanell said. The spiders were placed on and near the landslide with helicopters.The USGS was also able to provide immediate data on water levels and river discharge from an existing permanent streamgage located downstream on the North Fork Stillaguamish River at Arlington. My friends at Planet have very kindly acquired a high resolution (SkySat) image of the 22 February 2023 landslide at a coal mine at Alxa League in China . The Oso slide is a grim reminder about the complex nature of these slides and how fundamental ongoing efforts to understand them are to the health and security of the Nation. Further,the USGS is working with the National Weather Service on aDebris FlowWarning Systemto help provide forecasts and warnings to inform community and emergencymanagers about areas at imminent risk. Landslide insurance: Is it right for you? 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. Landslide debris blocked the North Fork Stillaguamish River, destroyed about 40 homes and other structures, and buried nearly a mile of State Route 530. 2023 Cox Media Group. They dissolve to liquid as more water is added. With the initial disaster response now over, longer-term questions have arisen regarding the stability Digital elevation models of the SR530 Landslide, created using structure from motion photogrammetry. The National Weather Service had issued flood warnings for several rivers around western Washington. Imagine trying to slide a large rock along a flat surfaceit's very difficult because of the friction between the rock and the surface. It is also referred to as the SR530 Landslide, as named by Snohomish County and Washington State. There is still much to learn about the Oso Landslide, as well as how and why landslides happen and behave in general. 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. Southwest Washington experienced its worst flooding in a decade and some rivers crested at more than 18 feet (5.5 meters) late Thursday, the National Weather Service said. 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. Share sensitive information only on official, secure websites. They may contain more coarse material than a mudflow when channelized. Security video shows distinct, red van may have been used in multiple break-ins in Seattle, Edmonds, Seven people arrested in Seattle connected to national drug trafficking operation, A look at Day 1 at Emerald City Comic Con. Flows may or may not be confined to a channel. Kolisch Road E (in Carbonado) is closed at the 32910 block due to a landslide. chevron_right Mines and Minerals. 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. A man wades through rising water from the nearby Skookumchuck River to take a photo in the town of Bucoda, Wash., Friday, as area rivers and snow runoff begin to accelerate flooding in the south sound. chevron_right Earthquakes. Leave the area immediately if it is safe to do so! That amount of material would cover about 600 football fields 10 feet deep. Shallow landslides typically occur during the winter months in western Washington and during the summer months in eastern Washington, but are possible at any time. Shallow Landslide Hazard Forecast website, Washington State Forest Practices Board Manual Evaluating Unstable Slopes, Washington State Landslide Insurance Page. This past summer, USGS scientists spent approximately three weeks mapping the geology and geomorphology of the landslide deposit. A landslide can easily destroy or bury a car or house. The inventory is given to decision-makers in the state, which helps them make informed planning decisions. Landslides exist throughout Washington State and can be triggered in many ways. Rotational slides often occur because the internal strength of the material is overcome by its own weight. Water also lowers the strength of the material which can make it less able to withstand the force of gravity. Landslides can occur as flows, slides, or falls and topples. This extra weight adds to the gravitational force. This buoyant force weakens the material and is also why your feet sink into beach sand after a wave washes over and adds water. Doors or windows stick or jam for the first time.

The Washington State Department of Transportation annually budgets for about $15 million in landslide cleanup for highways alone. This information can help legislators understand how vital USGS science is for assisting emergency planners and community leaders prepare for landslide events. USGS published research includes maps showing the relative ages of landslides similar in style and geographically near Oso, models that showed how quickly the landside mobilized, and information about the expected response of the North Fork Stillaguamish River to the ongoing erosion of the millions of tons of material deposited as a result of the landslide. Steeper slopes have a greater proportion of downhill force. These are clues that the ground is shifting. 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. Volcanic eruptions that produce loose ash deposits and debris flows.
