Scientists are collecting continuous data from those gages in order to analyze downstream movement of sediment and identify possible regions of accumulation. 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. Shallow landslides also occur as flows, slides, or rockfalls and topples. 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. When there is little water and low pore fluid pressure, most grains are touching and the material is relatively strong. Download forApple iOSorAndroid.

Watch a computer simulation of the SR530 landslide. Landslides are dangerous, unpredictable, and can occur rapidly. chevron_right Seismic Scenarios. Landslides cause widespread damage but are often under-represented and understudied compared to other potential geologic hazards such as earthquakes, tsunamis, and volcanoes. Experts also warned against logging on a plateau above the slope, because of risk of a catastrophic slide. Sudden changes in creek water levels, sometimes with increased sediment, especially during or right after large or protracted storm events. They dissolve to liquid as more water is added. For existing communities built on or near landslides, mitigation measures retaining trees and native vegetation on slopes, or keeping downspouts and driveways from draining onto slopes, for instance can reduce the potential of landslides reactivating. The USGS, working in collaboration with the Washington State Department of Transportation and the University of California, Berkeley, performed laboratory testing of soil samples from the landslide to identify the composition of the materials forming the landslide.

The cause of the recent slide that pushed a Bellevue home off its foundation this week is not yet known. Soil creep is the very slow (inches/year), steady, downward movement of soil or rock. Deep-seated landslides are typically much larger than shallow landslides, in terms of both surface area and volume. For more information, watch a video about USGS landslide science, and visit the USGS Landslide Hazards Program website. Deep-seated landslides can occur at any time. Coupled with climatic change prediction for more frequent and intense storm events, mapping and understanding geologic hazards can greatly reduce impacts to infrastructure, loss of life, and property. Seek out advisories and warnings during and after intense rainfall events. Creep is indicated by curved tree trunks, bent fences or retaining walls, tilted poles or fences, and small soil ripples or ridges. A volcanic eruption can rapidly melt snow and ice, causing a deluge of rock, soil, ash, and water that accelerates down the slopes of a volcano, devastating anything in its path.
