In a landslide, masses of rock, earth, or debris move down a slope. Landslides may be small or large, slow or rapid. They are activated by: storms, earthquakes, volcanic eruptions, fires, alternate freezing or thawing, and steepening of slopes by erosion or human modification. Landslide problems can be caused by land mismanagement, particularly in mountain, canyon, and coastal regions. In areas burned by forest and brush fires, a lower threshold of precipitation may initiate landslides. Land-use zoning, professional inspections, and proper design can minimize many landslide, mudflow, and debris flow problems. How can I protect myself from a landslide or debris flow?

Woodway, Washington Real-Time Monitoring of an Active Landslide above U.S. Highway 50, California Photograph of the Mill Creek landslide that closed Highway 50 for 4 weeks. CALTRANS Photo by Lynn Harrison, 1997 Click here for Real-Time Data During January 1997, several large landslides closed Highway 50 between Placerville and South Lake Tahoe, California. The photograph above shows the catastrophic Mill Creek landslide that closed Highway 50 for 4 weeks. A number of other landslides are currently active in this corridor. The U.S. Geological Survey, in cooperation with the Eldorado National Forest, has installed monitoring instruments on one currently active landslide that has the potential to affect Highway 50. Data from these instruments are used to detect changes in local conditions including: Rainfall Groundwater data from pressure sensors Movement data from displacement sensors Ground vibration from geophones. Data are collected every 15 minutes and displayed on graphs . In many landslides, infiltration of rainfall or rapid snowmelt increases groundwater pressures. These elevated pressures can, in turn, trigger landslide movement.

Natural Hazards Landslides Institutional links Atlas Home Explore Our Maps Environment Climate ... Atlas Help Search the Atlas Advanced Search The Atlas of Canada Landslides There is a wide variety of failure mechanisms and triggering causes, and local geological and topographic conditions that determine the type of landslide in a specific region. Some regions are particularly susceptible to landsliding: steep slopes in the mountains; weak Cretaceous bedrock along valleys in the Prairies; and valleys eroded into fine-grained sediments in areas once covered by glacial lakes and seas. Impact is greatest where landslide occurrence coincides with human activity. In the historical period (taken to be post-1840), landslides in Canada have resulted in more than 600 fatalities, including the destruction of several communities, and caused billions of dollars in damage. The hazard presented by landslides involves not only failure of ground beneath a structure and the impact or burial of moving debris, but also such secondary effects as landslide-dammed floods and landslide-generated waves. However, although landslides will continue to occur annually, landslide risk in our lives can be reduced or eliminated with proper planning and mitigation action.

28. Landslides In BC This illustrated and interactive site from Canada describes the different types and explains what causes them, where they occur, and how they can affect people. http://www.em.gov.bc.ca/Mining/Geolsurv/Surficial/landslid/

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.

29. Volcano Landslides And Their Effects 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. http://volcanoes.usgs.gov/hazards/landslide/index.php

USGS Home Contact USGS Search USGS Volcano Hazards Program ... Observatories Volcano Landslides and their Effects 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 km3 to more than 100 km3. 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 km3, 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! Landslides are common on volcanoes because their massive cones (1) typically rise hundreds to thousands of meters above the surrounding terrain; and (2) are often weakened by the very process that created themthe rise and eruption of molten rock. Each time magma moves toward the surface, overlying rocks are shouldered aside as the molten rock makes room for itself, often creating internal shear zones or oversteepening one or more sides of the cone. Magma that remains within the cone releases volcanic gases that partially dissolve in groundwater, resulting in a hot acidic hydrothermal system that weakens rock by altering rock minerals to clay. Furthermore, the tremendous mass of thousands of layers lava and loose fragmented rock debris can lead to internal faults and fault zones that move frequently as the cone "settles" under the downward pull of gravity.

Provoked by an earth tremor, extreme precipitation or man-made disturbances (such as a loud noise or the heavy movement of a skier or snowboarder), an avalanche can reach speeds of over 200 m/h (300 km/h). The impact of the falling material and the winds produced by the flow can cause extensive damage to anything in its path. According to experts, there are some 1 million avalanches yearly. The worst US avalanche occurred in 1910, when a snowslide swept two trains into a canyon in Wellington, WA , killing 96. In January 1962, an avalanche down an extinct volcano in Peru killed 3,000.

INTRODUCTION MAPS '82 DAMAGES SUGGESTED READING The U.S. Geological Survey produced special landslide hazard maps of the San Francisco Bay Area for the California State Office of Emergency Services (OES) and the National Weather Service (NWS) Now, these maps are available on-line The USGS has experience with catastrophic events associated with the winter storms of 1982 and 1983. New USGS maps are geared to reduce the loss of life and property from storm-induced landslides and debris flows (a.k.a. mudslides). Landslide maps identify areas where the greatest threat to property exists from the movement of deep-seated landslides ( see computer simulation from 1996-97 for example ). The areas potentially subject to slope failure generally coincide with the location of previous landslides and specific geologic materials. Now, fly-by movies are available: One fly-by depicts an animation of a slow-moving bedrock landslide, from a cross-sectional view. An instructional introduction is included in the animation. The other two animations show, as red patches, areas of mapped landslides in the East Bay Hills and in Marin County. These areas are part of the 85,000 landslides that have occurred sometime in the past throughout the Bay region.
