28. Landslides In BC bullet, How can we minimize the effects of landslides? landslides in British Columbia was originally produced as Information Circular 19937 by the http://www.em.gov.bc.ca/Mining/Geolsurv/Surficial/landslid/default.htm

Landslides in BC The Hope slide, 18 kilometres east of Hope, was one of the largest slides in Canadian history. The southwestern slope of Johnson Peak, collapsed on January 9, 1965, spreading 47 million cubic metres of debris, 85 metres thick, over a 3 kilometre stretch of the Hope-Princeton highway. The slide occurred in an unpopulated area in early morning hours and resulted in four deaths (photo courtesy of the Ministry of Environment, Lands and Parks). What do we mean by the word "landslide"? Landslide is a general term used to describe the down-slope movement of soil, rock and organic materials under the influence of gravity. It also describes the landform that results. British Columbia's steep, mountainous terrain, its complex geology, its high precipitation, both as rain and snow, its abundance of unconsolidated glacial sediments , and its geographic position astride the earthquake zone that surrounds the Pacific Ocean, all combine to make our province particularly susceptible to landslide activity. In fact, in British Columbia the loss of life and damage to property caused by landslides is greater than losses caused by other natural hazards such as earthquakes and flooding. As our cities, towns, roads and highways steadily encroach onto steeper slopes and mountainsides, landslide hazards become an increasingly serious threat to life and property. However, by understanding the answers to the following questions, we may be able to lessen the effects of landslides.

Story Tools RELATED Floods devastate China BEIJING, China (CNN) Weeks of heavy rain have caused at least three landslides along with heavy flooding in central and eastern China. The landslides happened over the weekend in Tibet, Sichuan, and Hubei provinces, China's official Xinhua news agency said Monday. In eastern China, there was a break Monday in rising water levels on the upper reaches of the Huai River. Farther downstream, however, the levels remained high in the eastern province of Jiangsu and at Hongze Lake. Residents near the lake remained on high alert, trying to man the dikes to contain the river or divert the water to release pressure. About a million people have been evacuated in Anhui, Jiangsu, and Hunan provinces so that water can be diverted to farmland there in order to protect the cities. An estimated 1.5 million people were working shifts to monitor the dikes for signs of leakage.

33. Puget Sound Landslides: Slope Stability Maps Shorelines and steep slopes are dynamic areas and many landslides have occurred since that time that are not reflected on these maps. http://www.ecy.wa.gov/programs/sea/landslides/maps/maps.html

Uses and limitations These maps are intended to educate the public about Washington's shoreline and to guide regional land use decisions. These maps should not be used as a substitute for site-specific studies carried out by qualified geologists and engineers. The Department of Ecology assumes no liability for the data depicted on these maps. For additional information, contact the Shorelands and Environmental Assistance Program, Washington State Department of Ecology. Not all slides have been mapped Designations, delineations, and boundaries were based on the best judgement of geologists and their depiction on the maps reflects the mapping and cartographic methods applied at the time. Due to either lack of geological evidence or to cartographic limitations, some unstable areas may not be fully identified on these maps. The Department of Ecology can make no warranty of the accuracy, completeness, or fitness for use of this information. Background The maps presented at this site were originally published in the Coastal Zone Atlas of Washington between 1978 and 1980. Although the Atlas has been out of print for many years, the maps contain useful information and remain the basis for many local planning decisions. The maps indicate the relative stability of coastal slopes as interpreted by geologists based on aerial photographs, geological mapping, topography, and field observations. Such methods are standard, but may occasionally result in some unstable areas being overlooked and in some stable areas being incorrectly identified as unstable. Important land use or building decisions should always be based on detailed geotechnical investigations.

Types and Effects Location Gas Lahars Landslides Lava Flows Pyroclastic Flows Tephra Volcano Landslides Start of landslide What are volcano landslides? Landslides are large masses of rock and soil that fall, slide, or flow very rapidly under the force of gravity. These mixtures of debris move in a wet or dry state, or both. Landslides commonly originate as massive rockslides or avalanches which disintegrate during movement into fragments ranging in size from small particles to enormous blocks hundreds of meters across. If the moving rock debris is large enough and contains a large content of water and fine material (typically, >3-5 percent of clay-sized particles), the landslide may transform into a lahar and flow downvalley more than 100 km from a volcano! Volcano landslides range in size from less than 1 km to more than 100 km . The high velocity (>100 km/hr) and great momentum of landslides allows them to run up slopes and to cross valley divides up to several hundred meters high. For example, the landslide at Mount St. Helens on May 18, 1980, had a volume of 2.5 km , reached speeds of 50-80 m/s (180-288 km/hr), and surged up and over a 400 m tall ridge located about 5 km from the volcano!

Home Practices Civil/Structural Engineering : Geotechnical, Geological and Geomechanical Engineering Geotechnical, geological, and geomechanical engineers and scientists work with large volumes of soil, rock, and fluids with properties that are poorly understood compared to the structures that they support. Failures of naturally complex soil and rock masses, and the structures built upon or within them, often occur because the initial geotechnical, geological, and geohydrological characterizations were inadequate. Exponent's Geotechnical, Geological, and Geomechanical Engineering (Geo3) staff provides unusually broad expertise in geotechnical engineering, geological engineering, engineering geology, geophysics, geomechanics, and groundwater hydrology to address a host of geo-failures, including landslides, foundation and retaining wall failures, oil-well distress, and floods, as well as earthwork construction claims.

Types and Effects Location Gas Lahars ... Tephra Landslide at Mount St. Helens volcano triggers explosive eruption on May 18, 1980 In the two months preceding May 18, 1980, magma moved high into the cone of Mount St. Helens and shoved the volcano's north side outward by at least 150 m. This dramatic deformation was called the "bulge." Within minutes of a magnitude 5.1 earthquake at 8:32 a.m., a huge landslide completely removed the bulge, the summit, and inner core of Mount St. Helens, and triggered a series of massive explosions. Magnitude 5.1 Earthquake Strikes Beneath North Flank 08:32:21 A.M. Northeast flank of Mount St. Helens; the bulge is located in right center of the volcano. Just after the earthquake, an eyewitness in an airplane directly over Mount St. Helens reported seeing material avalanche into its summit crater. Then, "everything north of a line drawn east-west across the northern side of the summit crater began to move as one gigantic mass... the entire mass began to ripple and churn up, without moving laterally. Then the entire north side of the summit began sliding to the north along a deep-seated slide plane." North Flank Collapses 08:32:47 A.M.

Natural Disasters FACT SHEET Landslides and Mudslides Download PDF version formatted for print (171 KB/2 pages) What landslides and debris flows are Landslides occur when masses of rock, earth, or debris move down a slope. Debris flows , also known as mudslides , are a common type of fast-moving landslide that tends to flow in channels. What causes landslides and debris flows Landslides are caused by disturbances in the natural stability of a slope. They can accompany heavy rains or follow droughts, earthquakes, or volcanic eruptions. Mudslides develop when water rapidly accumulates in the ground and results in a surge of water-saturated rock, earth, and debris. Mudslides usually start on steep slopes and can be activated by natural disasters. Areas where wildfires or human modification of the land have destroyed vegetation on slopes are particularly vulnerable to landslides during and after heavy rains.
