Know which areas are safe and how to reach them in an emergency. The principles at work are familiar to anyone who has ever built a sand castle. Immediately following the event, the USGS installed three rapid-deployment gages and three buoys to measure flow, sediment, and lake levels. 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. Click here to open the map in full screen. Alluvial fans are typically located on valley floors at the base of steep slopes where water transports sediment onto the fan surface. 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.

Changes in water well levels or water wells that suddenly run dry. The water may be deeper than it appears. This past summer, USGS scientists spent approximately three weeks mapping the geology and geomorphology of the landslide deposit. Research by the U.S. Geological Survey indicates that the landslides average speed was about 40 mph, with maximum speeds likely even higher. Always drain surface runoff away from slopes, fix plumbing leaks that could saturate soil, and plant and protect native ground cover and trees. Due to the photogrammetric methods used to collect these surveys, there may be substantial artifacts near the edges of the surveys, in areas of vegetation, or over extents of bare water, and should be used wi, 12201 Sunrise Valley Drive Reston, VA 20192, Region 2: South Atlantic-Gulf (Includes Puerto Rico and the U.S. Virgin Islands), Region 12: Pacific Islands (American Samoa, Hawaii, Guam, Commonwealth of the Northern Mariana Islands), developed for monitoring active volcanoes and landslides, Landslide Mobility and Hazards: Implications of the 2014 Oso Disaster, Preliminary Interpretation of Pre-2014 Landslide Deposits in the Vicinity of Oso, Washington, Digital elevation models of the State Route 530 landslide near Oso, Washington, July 2014 to July 2015.

The National Weather Service said Hoquiam, Washington, in Grays County received a record 5.78 inches (14.68 centimeters) of rain Thursday. 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. The same is true for landslidesfor the same kind of material, steeper slopes have less friction, making landslides more common. United States. Avoid placing fill soil, yard waste or debris on steep slopes, or excavating beneath them. However, our current ability to understand landslide hazards at the national scale is limited, in part because spatial data . Get breaking news alerts in the FREE FOX 13 Seattle app. hide caption.

Your county geologist or county planning department may have specific information on areas vulnerable to landslides. A landslide susceptibility map is planned to be released later this year to identify areas where small landslides may happen in the future. Risk MAP delivers high-quality data, risk assessment tools and mitigation expertise to communities, tribes, and state and local agencies in their efforts to reduce the risks from natural hazards including floods, earthquakes, wildfire, and landslides. Lahars are debris flows that originate on volcanoes. During the second stage of movement, the landslide greatly accelerated, crossed the North Fork Stillaguamish River, and mobilized to form a high-speed debris-avalanche. It is also referred to as the SR530 Landslide, as named by Snohomish County and Washington State. Stevens Pass on U.S. 2, White Pass on U.S. 12 and Blewett Pass on U.S. 97 also closed Thursday.

Secure .gov websites use HTTPS Official websites use .gov This accelerated movement was caused by the liquefaction of the saturated soils underneath the landslide, allowing the moving soil to quickly hydroplane across the river valley. The addition of water to material on a slope can make landslides more common. 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. All lanes of Interstate 5 in that area reopened Friday afternoon. Washington is one of the most landslide-prone states in the country, with hundreds to thousands of events each year. When there is little water and low pore fluid pressure, most grains are touching and the material is relatively strong. Seek alternative routes. The major route across Washington's Cascades I-90 over Snoqualmie Pass closed Thursday due to avalanche danger, heavy snow and low visibility. Most shallow landslides and flows occur during or up to several days after a heavy rainfall or rapid snowmelt event. When there is a lot of water and the pore fluid pressure is high, the water buoys up the grains and forces them apart. If escape is not possible, curl into a tight ball and protect your head.
