Types of Landslides ... Landslides in the US See simulation of a slide Contacts Researchers Join mailing list (c) APA What Are Landslides? The U.S. Geological Survey, working with other federal agencies, has efforts underway to study, plan, and mitigate landslide risks. So have some communities across the country. Many deal with landslides as part of flood control, erosion control, hillside management, earthquake hazard mitigation, road stabilization, and other programs. Perhaps the most common reminders of landslide risks are those "Watch For Falling Rocks" highway signs. Although "sliding rocks" is more apt, very few get to see a land slide. Occasionally we see small rocks or debris on the pavement, but a large size slide usually starts with such small incidents. Visually, a landside resembles a snow avalanche, only with a louder rumbling noise, and is capable of generating enough force and momentum to wipe anything in its path. One such devastating landslide wiped entire towns and villages in Columbia in 1985 when 20,000 died. The pictures you see on this web site are recent examples from around the country. They show what's left after a slide. In some cases, only the rail or pavement is mangled, in others a house or building crushed, but in almost every aftermath, the losses are real, the damages total, and the terrain changes permanent.

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!

Mass Movements Mass Movements Mass movement (commonly referred to as landslides) represents a geological process where surface materials move downhill by gravity. Most of the Martian mass movements occur in Valles Marineris, the Grand Canyon of Mars. Figure 2.1 shows a section of a collapsed canyon wall. At the top of the picture, a rock avalanche at the three curved walls is clearly visible. There is also a large amount of debris accumulated at the foot of the walls. A close-up view of the central curved wall is shown in Figure 2.2 . The fan-shaped feature at the bottom is the front of a debris flow on the valley floor. Figure 2.3 is another view of debris that piled up to modify the valley floor on a large scale. Notice the lineated tectonic grabens on top of the plateau. (Graben represents a downthrown block of land mass produced by horizontal tensions.) The existence of these linear grabens suggests that Valles Marineris was probably formed by horizontal stretching of the regional tectonic stresses. Another interesting feature occurred on the valley floors of the fretted or chaotic terrain as shown in Figure 2.4 . Notice the lineated features on the valley floors. They were probably formed by the debris deposits coming off the steep walls. There may be some slow, glacier-like, down-slope movements parallel to the lineations, but much of the movements are in the direction perpendicular to these linear features.

Time.com People Fortune EW Death toll nears 100 from Indonesia landslides JAKARTA, Indonesia Ninety four people have been killed in Indonesia's west Java after fresh landslides triggered by torrential rain slammed into villages over the weekend. The official Antara news agency said many of the dead were people looking for the metal in makeshift mines located in ravines and gorges around the villages. Heavy rains also triggered floods in parts of east Java over the weekend, although there were no casualties, the Jakarta Post newspaper reported. It said thousands of homes and hundreds of hectares of rice crops had been inundated by water. The wet season, which normally causes bouts of flooding across Indonesia, is scheduled to finish around April on Java, home to more than half the country's 210 million people. In Central Java, hundreds are bracing themselves for a possible eruption by Mount Merapi.

Grade 7 Natural Disasters Project Landslides Landslides occur when a portion of a hillslope becomes too weak to support its own weight. This weakness is generally initiated when rainfall or some other source of water increases the water content of the slope, reducing the strength of the materials. Other causes of landslides include earthquakes and loud sounds. Many types of landslides move seasonally or periodically and may lie dormant for years. Landslides are generally classified into slides, falls and flows. Slides move as large bodies by slipping along one or more failure surfaces. Falls of rock or soil originate on cliffs or steep slopes. Large rockfalls can be catastrophic events. An earthquake off the coast of Peru in 1970 started a rockfall which accelerated to more than 170 miles per hour and buried more than 18,000 people. Flows are landslides that behave like fluids. Mudflows involve wet mud and debris. Earthflows involve wet, claylike material. Solifluction is the downslope flow of soil that occurs on arctic and alpine hillsides when thawed ice or snow saturates the soil cover. Landslides constitute a major geologic hazard because they occur in all 50 states, causing $1-2 billion in damages and more than 25 deaths each year. Landslides commonly occur with other major natural disasters, such as earthquakes and floods. The 1980 eruption of Mount St. Helens in Washington was preceded by the development of a large landslide on the north side of the volcano. The Northridge earthquake in 1994 in the San Fernando Valley triggered thousands of landslides in the Santa Susanna Mountains north of the epicenter.

INTRODUCTION MAPS '82 DAMAGES SUGG. 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. Debris flow/mudslide maps show areas where life-threatening debris flows would likely occur in the event of an intense winter rainstorm such as that of January, 1982 (
