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 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 USGS also worked with partners to obtain and study soil samples from the landslide area to better understand the landslides characteristics and behavior. Photo by G.W. Debris flows usually occur in steep gullies, move very rapidly, and can travel for many miles.

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. Block slides are a type of translational slide that occur when large and relatively intact slabs of rock or earth are rapidly transported downslope. When there is a lot of water and the pore fluid pressure is high, the water buoys up the grains and forces them apart. This is because the force of gravitywhich acts to move material downhillis usually counteracted by two things: (1) the internal strength of the material, and (2) the friction of the material on the slope.

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. The force of rocks, soil, or other debris moving down a slope can devastate anything in its path. Cracks in walls, bulging walls or cracks in floors. Data. These landslides usually occur as translational slides, rotational slides, or large block slides. Since 2015, the Washington Geological Survey has maintained a Google map of recently reported landslides for the state.
