A high density of landslides were found along Puget Sound bluffs, river corridors, and upland areas of the Cascades. United States. Translational slides usually fail along geologic discontinuities such as faults, joints, bedding surfaces, or the contact between two rock types. Exceptionally high tides and winds were causing coastal flooding around homes in Birch Bay, according to the Whatcom County Sheriff's Office. Consult professionals if you suspect you are on a landslide. Topography of a slope its shape, size, degree of slope and drainage. All lanes of Interstate 5 in that area reopened Friday afternoon. Don't assume that highways are safewatch for collapsed pavement, mud, fallen rock, or other debris on the roadway. The other type of landslide is called a deep-seated slide. A hillside that has increased spring and (or) seep activity, or newly saturated ground, especially if it was previously dry. An official website of the United States government. She won the jackpot. 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. USGS research on the North Fork Stillaguamish River is aimed at identifying potential impacts to the aquatic ecosystem and changes to flood risk along the river corridor including newly reconstructed stretches of State Route 530 and downstream bridges. 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. A landslide is the movement of rock, soil and debris down a hillside or slope. Experts also warned against logging on a plateau above the slope, because of risk of a catastrophic slide. Consult a licensed engineering geologist or licensed geotechnical engineer if you would like a site-specific evaluation. The USGS also works with the National Weather Service in several locations on the West Coast to assist communities at risk for landslides. Under the appropriate circumstances, any landslide type can pose a serious hazard to life or property. There are hundreds of such slides across Washington, Hanell notes, that moved under different climate conditions and are presently dormant. A man wades through rising water from the nearby Skookumchuck River to take a photo in the town of Bucoda, Wash., Friday, as area rivers and snow runoff begin to accelerate flooding in the south sound. Landslides are damaging and deadly, and they occur in every U.S. state. They can travel great distances and damage structures in flat areas far from their source. A reminder to drivers: do not drive through flooded roadways if they are not already blocked off. The spiders were placed on and near the landslide with helicopters.The USGS was also able to provide immediate data on water levels and river discharge from an existing permanent streamgage located downstream on the North Fork Stillaguamish River at Arlington. Rotational slides (slumps) are landslides that occur along a curved or spoon-shaped surface. Washington State has the second highest risk of earthquakes in the U.S. Remember that flooding may occur after a mudflow or a landslide. A large landslide occurred in northwest Washington on March 22, 2014, leading to tragic loss of life and destruction of property. The area overrun by the landslide was about one half square mile, and the landslide moved about 18 million tons of sand, till, and clay. What happens next, explains Washington State Geologist Casey Hanell of the DNR, is predictable and in some cases, preventable. USGS scientists develop tools and produce maps of areas susceptible to landslides and identify what kinds of conditions will most likely lead to such events. USGS research indicates that the landslides average speed was about 40 miles per hour, with maximum speeds likely even higher. By knowing where landslides are, local officials and residents can take proper care to reduce the likelihood of reactivating the slides. Understanding how and why these landslides move help geologists develop mitigation techniques and determine future hazards for roads, houses, infrastructure, and human life. If you are in immediate danger, evacuate and call 911. Know which areas are safe and how to reach them in an emergency. Please contact gs-haz_landslides_inventory@usgs.gov for more information on how to contribute additional inventories to this community effort. The slope material loses strength and runs out, often forming a bowl or depression at the head. Rudraprayag and Tehri Gharwal of the Himalayan state of Uttarakhand have been the most landslide-affected districts over the last two decades, suggests satellite data captured by the Indian Space Research Organisation (ISRO). With the initial disaster response now over, longer-term questions have arisen regarding the stability Digital elevation models of the SR530 Landslide, created using structure from motion photogrammetry. Posting comments is now limited to subscribers only. These landslides usually occur as translational slides, rotational slides, or large block slides. Pore fluid pressure is the pressure that water exerts on all of the nearby grains. Landslide debris covered about 40 homes and other structures as well as nearly a mile of State Route 530.

If 1 acre of land soaks up 1 inch of rain, the land gains about 234,000 pounds. Shortly following the landslide, the USGS assisted state and local agencies by providing emergency landslide monitoring and flood threat information to ensure that if the landslide moved again, warning could be provided to emergency response teams involved in rescue and recovery efforts. Saturation, by snowmelt or heavy rains, that weaken rock or soils on slopes. These type of landslides can be large and damaging and occur where alternating layers of strong and weak rock slope downhill. Flows usually occur in fine-grained material on moderate, water-saturated slopes.

Consult a professional geotechnical expert for advice on corrective measures you can take. Tidal flooding of homes and businesses also affected towns including Edison and University Place. These are clues that the ground is shifting. Replant damaged ground as soon as possible. This extra weight adds to the gravitational force. When there is little water and low pore fluid pressure, most grains are touching and the material is relatively strong. Remember to help your neighbors who may require special assistance infants, elderly people, and people with disabilities.

It will slide. They may contain more coarse material than a mudflow when channelized. chevron_right Geothermal Resources. This cut the river bed back to near its pre-landslide elevation and effectively drained the remaining excess water by the middle of May. Dont ignore the sign of soil movement, Hanell said. The goal of USGS landslide science is to help answer questions such as where, when, and how often landslides occur and how fast and far they might move. Some of them include: October 11, 2009 - A massive landslide in the Nile Valley of Yakima County closed a section of Highway 410 west of Naches, destroying two homes, and changing the flow of the Naches River. Leave the area immediately if it is safe to do so! Shortly following the landslide, the USGS and partnering agencies provided near-real-time information on the potential for additional landslides and flood threats to search and rescue personnel. The USGS has been conducting field work, soils laboratory testing, and additional analyses to identify the likely causes of the large mobility of the Oso landslide. Pushing the rock is easier if the surface slopes downhill or is slippery. The data on this website are meant to provide general information only; real landslides have many variables. Some homes flooded and at least one apartment building was evacuated, KIRO-TV reported. Precipitation in the area during February and March 2014 was 150% to 200% of the long-term average, and likely contributed to slides initiation and mobility, the USGS analysis found. Listen to a battery-operated radio or television for emergency information. Landslides take lives, destroy homes, businesses, and public buildings, interrupt transportation, undermine bridges, derail train cars, cover marine habitat and damage utilities.
