British Columbia and Washington reeling from flooding and landslides Many of the landslide areas in Washington are a mixture of different slide types. Most shallow landslides and flows occur during or up to several days after a heavy rainfall or rapid snowmelt event. Scientists are collecting continuous data from those gages in order to analyze downstream movement of sediment and identify possible regions of accumulation. All of these properties are important for landslides. New cracks appear in plaster, tile, brick or foundations. Landslides occur when the strength of material on a slope becomes less than the force of gravity acting on the material. Other areas saw nearly half of the rain they'd expect to see for the month of January in one day, according to the weather service. Landslides nearly always move down a slope. Locations that experienced landslides in the past are more likely to have future landslides. The Oso landslide, also known as the SR 530 landslide, occurred in northwest Washington state on March 22, 2014, leading to devastating loss of life and destruction of property.

If you think there is danger, evacuate immediately. The ground slopes downward in one specific direction and may begin shifting in that direction under your feet. This work has helped researchers understand how soils may move in other areas that have a similar soil composition. 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. But its up to the homeowner to research and, if needed, take preventive measures, including hiring a geotechnical engineer for a site survey.

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. These slides typically move slowly over decades, even centuries. Scientists with the U.S. Geological Survey (USGS)continue to supportall of those involved in responding to the event to assess ongoing hazards and identify possible future impacts. These include a partnership to implement a Debris Flow Warning System to help provide forecasts and warnings to inform community and emergency managers about areas at imminent risk for debris flows following forest fires. 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 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. Published findings from USGS studies are already being used by planners and emergency response officials to understand the context in which the landslide occurred and the potential impacts of landslides like Oso. Avoid placing fill soil, yard waste or debris on steep slopes, or excavating beneath them. 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. State agencies and local jurisdictions are coordinating resources to address damaged property and infrastructure, assess damage caused by the storms and implement repairs, he said. The heavy rain has caused several landslides to block road access. A landslide is the movement of rock, soil and debris down a hillside or slope. They typically do not mobilize far and sometimes move like a snow avalanche. The landslide involved a complex sequence of eventsincluding rotation, translation, and flow mechanismsand can be referred to as a debris-avalanche flow.
