Volcano landslides range in size from less than 1 km to more than 100 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! Landslide enters valley Illustrations by B. Myers How are volcano landslides generated? 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.

Landslides and Mass-Wasting Gravity is a constant force, always pulling towards the center of the Earth. This tireless force moves material "down hill" in a process known as mass-wasting . Most people think of mass wasting in terms of landslides , which is a rapid displacement of rock and soil (which is a major hazard almost 2 billion dollars per year losses in the US alone!). However, mass-wasting covers many different phenomena, some of which are quite slow. Classifications of Mass-wasting A slump is a type of slope failure which involves the rotational movement of soil or rock a fall is a sudden, nearly vertical movement of rock or soil for example from an overhanging cliff. A slide is similar to a slump except the material does not rotate. Block slides have coherent blocks move down the hill side, while a debris slide is a jumble of material. A flow is the rapid movement of a mixture of rock/soil with a significant component of water or air. Creep is an imperceptibly slow flow. Factors controlling Mass-wasting hazards Disaster occurs when mass wasting interacts with human society. In general, this means that certain factors conspire to cause a

The accident brings the number of people killed in the country to 41 as a result of heavy rains, which began last Friday. Tuesday's victims were waiting for the reopening of the road that leads to Baeza, 30 miles east of the capital. It was shut down Monday as a result of several landslides. None of those caused any injuries. Elsie Andrade, a National Civil Defense spokeswoman, said the victims "had set up an improvised camping ground, where they were waiting for the highway to be reopened when the mountain fell on top of them." Communication with the remote area, where cell phones and radio transmissions do not work, was difficult. Red Cross workers, fire officials and police were searching for any possible survivors, trying to recover the victims' bodies, and said more dead could be buried under the mountains of mud which covered the narrow highway, a rural road that leads to the Amazon.

Heavy snowstorms were followed by a warming trend that caused quick melting, runoff and flooding. This period was then followed by rain. This lead to over 100 slides in King County over the subsequent two-month period. King County was also hard hit by landslide damage in 1972. The Seattle area was particularly hard hit due to urbanization and geologic conditions. Although landslides can and do occur in almost any part of the state, the most vulnerable areas are the Puget Sound Basin and King County. Due to the high population density and the fact that many structures are built either on top of or below bluffs and slopes subject to land sliding, more lives are endangered 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.

ugs utah geology geologic hazards / landslides House damaged by the April 6, 2004 debris flow in Farmington, Utah. Landslides are common natural hazards in Utah. They often strike without warning and can be destructive and costly. Common types of landslides in Utah are debris flows, slides, and rock falls. Many landslides are associated with rising ground-water levels due to rainfall, snowmelt, and landscape irrigation. Therefore, landslides in Utah typically move during the months of March, April, and May, although debris flows associated with intense thunderstorm rainfall are common in July.

Previous News for January 2002 Next Probe to predict landslides and earthquakes 17 January 2002 et al Appl. Phys. Lett. Zimanowski and co-workers pressed together two pieces of volcanic rock and then slid one across the other. Electrodes in each rock monitored the electromotive force that built up between. Although the sliding force was constant, the researchers found that the electrical signal peaked periodically, shortly before any movement was detected. Based on this experiment, Zimanowski and colleagues developed a probe and used it to measure electrical signals at Mount Stromboli, an active volcano in Italy where landslides are frequent. The detector revealed a pattern in the signals similar to that in their experiment, and the team proposed a four-step process to explain it. Initially, the researchers believe, strain builds up between the layers of rock. 'Micro-cracks' then form at the rock surfaces as they creep over each other, exposing fresh rock. This causes electrical charge to accumulate, which generates the 'precursor signal'. Mechanical failure follows as the rocks slip past each other, and finally the interface relaxes and the electrical charge dissipates. According to the German team, this technique would be suitable for monitoring unstable mountainsides, in particular because it gives advance warning of landslides and volcanoes. 'The field probe is buried between 30 and 50 centimetres in the ground but its detection depth is presently one to two kilometres into the Earth's crust', Zimanowski told PhysicsWeb. Improvements to the probe could increase this to a depth of several kilometres, say the researchers, which could enable it to detect the precursor tremors of certain types of earthquake as well.

LANDSLIDES Landslide in Conecuh County, Alabama, 1997 WHAT IS A LANDSLIDE? A landslide is defined as a perceptible downward and outward movement of slope-forming soil, rock, and vegetation under the influence of gravity. WHAT CAUSES A LANDSLIDE? Landslides can be triggered by both natural and human-induced changes in the environment. These changes may result from weaknesses in the composition or structure of the rock or soil, heavy rain, or changes in ground-water level, seismic activity, or construction activity. Human- induced landslides may result from changes in slope caused by terracing for agriculture, cut-and-fill construction for highways, building construction, mining operations, and changes in irrigation or surface runoff. TYPES OF LANDSLIDES Rock falls are rapid movements of bedrock characterized by free-fall, bouncing, and rolling. A topple is a block of rock that tilts or rotates before falling to the slope below. Slides are movements of soil or rock along a distinct surface of rupture which separates the slide material from the more stable underlying material. The two major types of slides are rotational and translational slides Flows are mass movements of water-saturated material. Different types of flows include creep, debris flow, debris avalanche, earthflow, mudflow, and lahar.

See Module Preview for initial information and a Powerpoint Presentation. Introduction - Heavy rains saturate the Portland, Oregon area. Slick, debris-filled mud slides down steep slopes blocking the scenic Columbia River Gorge Highway. - Warm rains rapidly melts snowpack. Snowmelt-induced debris flow threatens lives and damages property. - A major earthquake hits the West Coast. It triggers numerous landslides in a 200-mile radius. Each of these events represents some type of slope failure . Slope failure, also referred to as mass wasting , is the downslope movement of rock debris and soil in response to gravitational stresses. Three major types of mass wasting are classified by the type of downslope movement. The types of movement, falls, slides, and flows , will be covered in this module. In addition, another type of ground failure

Is Montana at Risk? Identified Hazards for the State of Montana Basic Disaster Information: The Four Phases Hazardous Materials Severe Weather Flooding ... Miscellaneous LANDSLIDES / SOIL FAILURE Landslides are among the most common natural hazards. As with most natural hazards, they are often characterized by the catastrophic examples, such as the Hebgen Lake Quake Lake slide of 1959. Unlike most natural hazards, however, most damage is not caused by extreme events, but by uncounted (and often unreported) minor events. Slopes with the greatest potential for sliding are between 34 degrees and 37 degrees. Although steep slopes are commonly present where landslides occur, it is not necessary for the slopes to be long. Therefore, landslides are one major natural hazard that is as likely, or perhaps more likely, to occur in eastern Montana as in the mountainous western part of the state. Two criteria are typically used to classify landslides - types of movement and types of material. The types of movement are falls, topples, slides, spreads, flows, and combinations or two or more of these. Bedrock and soils are considered the principle material types. The soils type is further divided into debris and earth. Landslides occur when the shearing of forces exceed the resisting forces of earth materials. Several factors contribute to either increased shear stress or reduced shear strength, thus initiating the landslide process. Factors which can increase shear stress are:

Devastating Landslides Strike Fiji Posted on Tue, 18 May 2004 16:19:55 GMT Fiji Red Cross staff and volunteers have led the response to a devastating storm that struck the Pacific nation last week, killing at least ten people with several more still missing. The tropical storm brought heavy rainfall and 90km/h winds to central areas of Fiji's largest island, Viti Levu, causing landslides and flooding in low-lying areas. In the worst fatal incident, a landslide pushed a bus carrying five people into the flooded Wainibuka River, north of Suva. According to Fiji's National Emergency Operations Centre, about 10,000 people have been directly affected by the storm, through extensive damage to infrastructure, crops and households. "With the tropical cyclone season almost over, we had been hoping that Fiji would escape any major natural disasters this season," said Fiji Red Cross Director-General Alison Cupit. "However, this storm has changed that, bringing a real dampener to Easter holiday celebrations." On the evening of Thursday 8 April, just hours after the storm had struck, Fiji Red Cross branch volunteers were providing immediate assistance in the field and at evacuation centers.
