Spiders contain high-precision GPS units for detecting landslide movement as well as geophones for detecting small vibrations. Shallow landslides also occur as flows, slides, or rockfalls and topples. Sudden changes in creek water levels, sometimes with increased sediment, especially during or right after large or protracted storm events. A landslide usually occurs because the internal strength of the rock, soil, or sediment becomes less than the force of gravity. Posting comments is now limited to subscribers only. Share sensitive information only on official, secure websites. There are hundreds of such slides across Washington, Hanell notes, that moved under different climate conditions and are presently dormant. You hear a faint rumbling sound that increases in volume as the landslide nears. The initiation of slides, like flows or rockfalls, is sensitive to steep slopes, the additional weight of water or other loads, and friction along their base. Areas above or below steep slopes, or in areas known to have frequent landslides, are more likely to experience landslides in the future. The slope material loses strength and runs out, often forming a bowl or depression at the head. The data is assembled into a database and susceptibility maps are produced using the data. The layer of saturated soil and debris eventually will slide in a quick sloughing of material. Seek out advisories and warnings during and after intense rainfall events. 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. The ground slopes downward in one specific direction and may begin shifting in that direction under your feet. The landslide involved a complex sequence of eventsincluding rotation, translation, and flow mechanismsand can be referred to as a debris-avalanche flow. It will slide. Earthflows may have a characteristic 'hourglass' shape. Control runoff from buildings and roads so it flows away from steep slopes and into natural drainages or storm drains. The Legislature directed the Department of Natural Resources to identify and map landslides throughout Washington and disseminate the information to the public. Translational slides can contain loose sediments or large slabs of bedrock.
