Podcasting Personal Preparedness Basic-Better-Best! Avalanches ... CONTACT EMERGENCY SERVICES Office of Emergency Management You're in Emergency Services Landslides print Landslides Photo provided by King County Executive's Office Landslides can be a dangerous secondary hazard when initiated by severe storms . The power of these land movements was exemplified in the severe winter storm that hit the Puget Sound region in December 1996 and January 1997. During this storm, heavy snowfall was followed by a warming trend that caused quick melting, runoff and flooding, followed by a period of rain. This led to over 100 slides in King County over the subsequent two-month period. Severe storms are not the only cause of landslides. The Nisqually earthquake in February 2001 caused a portion of hillside near Jones Road in the Renton area to slide into the riverbed of the Cedar River. The flow of the river was partially blocked resulting in several homes along the river being damaged by the dammed waters. Evidence of slide activity can still be seen along the eastern side of Interstate-5 from King County Airport all the way to the Interstate-90 interchange where portions of hillside collapsed carrying trees and debris downhill, falling just short of impacting Interstate-5. Although landslides can and do occur in almost any part of the state, geographic King County and the Puget Sound Basin are especially vulnerable due to our urban environment and unique geological conditions. Because of our high population density and the fact that many structures are built either on top of or below bluffs and slopes subject to landslides, more lives are endangered during these land movements and there is a greater potential for damage or destruction to private and public property. Many of the major valleys and shoreline bluffs of Puget Sound are bordered by steeply sloping unconsolidated glacial deposits that are highly susceptible to landslides. Other vulnerable areas include the Cascade Mountain passes leading to eastern Washington. As a result, allowing for the possibility of a landslide occurring in our area is an essential component to your family emergency plan.

Forestry Sciences Laboratory, Pacific Northwest Research Station, U.S. Forest Service Abstract: Most forests are managed. As a result, landslides and debris flows are managed implicitly. Our objective is to model landsliding and debris flow runout in some detail over large areas and a century in time as part of the Coastal Landscape Analysis and Modeling Study (CLAMS). We want to capture the interactions between the forest and the landslide/debris flow process. What are the process implications of management decisions? ``Area-Descriptiveness'' Space: Landscape modeling usually involves a trade-off between the descriptiveness of the model and the area modeled. Process models usually describe a small area in detail over geologic time. GIS-based index models usually describe a large area in less detail at a static moment in time. We attempt a compromise in area-descriptiveness space by lumping landslide source areas and resolving the channel network at high resolution.

Community Role City Government Role ... News Landslides Landslides are common in Seattle. Late winter and early spring are the most common times for slides, with most of the documented slides in Seattle occurring in January. Nearly all landslides in Seattle result when excess water is involved, and the majority of landslides also involve human factors of some type. The probability of a slide event rises after a wet, cold winter, especially if a freeze occurs in late winter and early spring. The ground becomes saturated over the winter, and then porous following a freeze, so a subsequent rain will penetrate the surface while the high water table will prevent the ground from absorbing it. The water increases the slope stress by adding weight and increasing pore pressure within the soil. Major Incidents Year Locations Impacts Magnolia, West Seattle

Recent testing in Italy has shown that the four-tonne Roboclimber can secure slopes without endangering human lives, thanks to innovations from Europe's space programmes. "It was amazing to see how easily this huge robot managed to operate on a very steep slope to secure a rocky mountain wall,” said Guglielmo Berlasso, Director of the Civil Protection Office in the Friuli-Venezia Giulia region in Italy, where the demonstration took place. Landslide in northern Italy Landslides are a big problem in Italy. More than 400 take place each year causing an estimated €1200 million of damage and often deaths. In the 20th century 5939 people were declared dead or missing due to landslides. Alfredo Sandovar from the European Commission was also present at the Roboclimber demonstration and expressed his great satisfaction with the results. “We are aware of the big dimension of this problem which is why we decided to finance this project,” he said.

51. Landslide Information From The Colorado Division Of Emergency Management landslides occur when masses of rock, earth, or debris move down a slope. They may be small or very large, and can move at slow to high speeds. http://www.dola.state.co.us/dem/public_information/landslide.htm

Colorado.gov Live Help Advanced Search Department Home ... Colorado Emergency Management Association Landslides Landslides occur when masses of rock, earth, or debris move down a slope. They may be small or very large, and can move at slow to high speeds. They are activated by such things as storms and fires, earthquakes, volcanic eruptions, rock and soil weakened through saturation by snowmelt or heavy rains and excess weight from accumulation of rain or snow, stockpiling of rock or ore, or waste piles. Man-made structures may stress weak slopes to failure creating a landslide. Debris flow across I-70 after Storm King Mountain fire Slope materials that become saturated with water may develop a debris flow or mud flow. The resulting slurry of rock and mud may pick up trees, houses, and cars, thus blocking bridges and tributaries causing flooding along its path. Where do landslides occur? Landslides occur in every state. The Appalachian Mountains, the Rocky Mountains, and the Pacific Coastal Ranges and some parts of Alaska and Hawaii have severe landslide problems. Any area composed of very weak or fractured materials resting on a steep slope can, and probably will, experience landslides. Click on the link here for the USGS webpage. They have a lot of information on the the DeBeque Canyon landslide in Colorado.

Original Caption Released with Image: Recent Galileo images of the surface of Jupiter's moon Callisto have revealed large landslide deposits within two large impact craters seen in the right side of this image. The two landslides are about 3 to 3.5 kilometers (1.8 to 2.1 miles) in length. They occurred when material from the crater wall failed under the influence of gravity, perhaps aided by seismic disturbances from nearby impacts. These deposits are interesting because they traveled several kilometers from the crater wall in the absence of an atmosphere or other fluids which might have lubricated the flow. This could indicate that the surface material on Callisto is very fine-grained, and perhaps is being "fluffed" by electrostatic forces which allowed the landslide debris to flow extended distances in the absence of an atmosphere. This image was acquired on September 16th, 1997 by the Solid State Imaging (CCD) system on NASA's Galileo spacecraft, during the spacecraft's tenth orbit around Jupiter. North is to the top of the image, with the sun illuminating the scene from the right. The center of this image is located near 25.3 degrees north latitude, 141.3 degrees west longitude. The image, which is 55 kilometers (33 miles) by 44 kilometers (26 miles) across, was acquired at a resolution of 100 meters per picture element.

54. JCP Reports - Hazard Information - Landslides This article will deal with how geologists and engineers define and recognize landslides and where a slide might be expected to occur. http://www.jcpreports.com/html/articles/landslide.html

Hazard Information - Landslides By JCP Geologists Although rainstorms are extremely welcome to California, those same storms also can bring a taste of what that welcomed water can do in hillside areas. This article will deal with how geologists and engineers define and recognize landslides and where a slide might be expected to occur. A landslide is a downward movement of rocks and soil. However, it might also include such things as vegetation, structures, or parts of roadways. Sometimes the soil can liquify and the slide then becomes a mudflow which acts much in the same way as a stream of water. Landslides may move as slowly as two inches a year, such as the Penitencia Creek Landslide in San Jose, however, speeds in excess of 20 miles as hour have occurred. Landslides occur in all sizes and shapes. They can be backyard size, or they can be a couple of miles long. Landslides can be shallow or deep, and they can move a few inches or several miles. There are also numerous types of landslides. They range from rock falls (such as those in Yosemite Valley) to landslide-mudflows that can occur on very gentle slopes as low as 15 degrees. Homesites in hillside areas may experience landslide problems if they were not properly designed or located relative to existing slope or other conditions on the property. Many landslides are man-made, caused by cutting roadways and building pads, or placing improperly engineered fill on steep slopes. Earthquakes can trigger landslides, but the most common triggering mechanism is the combination of heavy rainfall, steep slopes, and loose or soft soil. Even slopes that appear stable when dry can experience a landslide if the soil becomes saturated by an intense storm or series of storms. Other sources of excess water such as broken pipes, intensive landscape watering, or misdirected run-off can also trigger a landslide. Hillside areas burned off by forest fires are also particularly susceptible to landsliding because of the absence of vegetation to bind the soil.

Ten additional deaths were reported in six provinces in the eastern Bicol region, from the 35 already reported last week, while 31 people were reported injured, the Office of Civil Defence said. Landslides and floodings have affected 137 towns in the Philippines since last week, and have displaced some 873,000 residents who sought shelter in evacuation camps, it said. Weather forecasters say more flooding was expected in the coming days. In the latest incident, up to four feet of water inundated the town of Sulop in southern Davao del Sur province, forcing 15 families to seek shelter in a Catholic church which was on higher ground. Landslides also cut off gold panning areas in Compostela Valley in Mindanao due to continuing rains.

Devised originally for Baguio City, Philippinesa city that averages five typhoons annually and holds the world record for most precipitation received in a 24-hour period (46 inches on July 14-15, 1911)the risk rating system relies on data commonly available in developing countries. The engineers use information about the history of landslides, the type of bedrock underlying a slope, the inclination of the slope and the type of vegetation growth to determine an area's hazard rating, which they then look at in combination with land use and population density to determine the overall risk rating. "The system could be applied directly to any country with similar topography, geology and climate, which would be much of Southeast Asia," said Herbert Einstein, a professor in the MIT Department of Civil and Environmental Engineering. He and Artessa Saldivar-Sali, a Filipino who spent summers with her family in Baguio, developed the system as part of her master's degree thesis work.
