Deep-seated landslides can also occur at any time. Immediately following the event, the USGS also installed three rapid-deployment gages and three buoys to measure flow, sediment, and lake levels. Boeing employee bought lottery ticket because it was at $747M, a nod to the aircraft. Avoid placing fill soil, yard waste or debris on steep slopes, or excavating beneath them. It is important to note that the type or size of landslide is largely irrelevant if you happen to be the one in harm's way. 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. A landslide is blocking the roadway in the 2200. Stress from earthquakes magnitude 4.0 and greater can cause weak slopes to fail. Stevens Pass on U.S. 2, White Pass on U.S. 12 and Blewett Pass on U.S. 97 also closed Thursday. A more comprehensive list of significant landslides in Washington is available here. Scientists are collecting continuous data from those gages in order to analyze downstream movement of sediment and identify possible regions of accumulation. The layer of saturated soil and debris eventually will slide in a quick sloughing of material. Landslide mobility might have been far less if the landslide material had been slightly denser and/or drier. Excess weight, from accumulation of rain or snow, from stockpiling of rock or ore, from waste piles, or from manmade structures, may stress weak slopes to failure. Share sensitive information only on official, secure websites. A large landslide occurred in northwest Washington on March 22, 2014, leading to tragic loss of life and destruction of property.
