Warning Signal Cyclones Flooding Severe Storms ... Disasters Landslides usually involve the movement of large amounts of either earth, rock, sand or mud or any combination of these. Landslides can be caused by earthquakes, volcanoes, soil saturation from rainfall or seepage or by human activity (eg. vegetation removal, construction on steep terrain). The rate of movement of a landslide can vary from exceptionally slow - centimetres per year, to a sudden and total collapse - such as an avalanche of perhaps millions of tonnes of debris. The distance travelled by landslide debris can also vary greatly, from a few centimetres in 'ground slumps', to many kilometres when large mud flows follow river valleys. The Department of Emergency Services' purpose is to save lives, protect property and help preserve the natural environment through the delivery of emergency and disaster management services.

Home FACT SHEET Landslides and Mudslides November 17, 2003 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. Health threats from landslides and debris flows In the United States, landslides and debris flows result in 25 to 50 deaths each year. The health hazards associated with landslides and mudflows include:

Main December 29, 2003 Logging and Landslides Dec. 29, Humboldt County, California - It's flooding in Elk River. Roads are washed out after only 3.2 inches of rain. This morning, residents were stranded, unable to get to or from their homes. Meanwhile, Maxxam is gearing up to cut another 600 acres in those valleys, worsening conditions already brought about by fifteen years of liquidation logging. In Southern California, rescue teams are still digging through the mud for victims of landslides triggered by rains following the massive arson fires of October 2003. CNN is airing animated reenactments of naked soil exposed to pelting rain, the ground swelling and giving way, creating mud and debris torrents that wipe out houses, RVs, and people. They do not question the causation: landslides are triggered by loss of trees. 200 people are either dead or missing in the Philippines from a flash flood and landslides last week caused by logging When logging triggers landslides Given that even the most corporate of news outlets can see the relationship between clear-cuts and landslides, why must Humboldt County residents continue to endure the result of high-speed logging by an outside corporation?

LANDSLIDES IN OHIO Landslides are a significant problem in several areas of Ohio. The Cincinnati area has one of the highest per-capita costs due to landslide damage of any city in the United States. Many landslides in Ohio damage or destroy homes, businesses, and highways, resulting in annual costs of millions of dollars. Upon occasion, they can be a serious threat to personal safety. On Christmas Eve 1986, an individual traveling in an automobile was killed by falling rock along U.S. Route 52 in Lawrence County in southern Ohio. Although this is Ohio's only recorded landslide fatality, there have been numerous near misses. TYPES OF LANDSLIDES The term landslide is a general term for a variety of downslope movements of earth materials. Some slides are rapid, occurring in seconds, whereas others may take hours, weeks, or even longer to develop. ROTATIONAL SLUMP Landslide in westbound lanes of I-70 near New Concord, Muskingum County, 1986. Major components of a rotational slump. A rotational slump is characterized by the movement of a mass of weak rock or sediment as a block unit along a curved slip plane. These slumps are the largest type of landslide in Ohio, commonly involving hundreds of thousands of cubic yards of material and extending for hundreds of feet. Rotational slumps have an easily recognized, characteristic form. The upper part (crown or head) consists of one or more transversely oriented zones of rupture (scarps) that form a stair-step pattern of displaced blocks. The upper surface of these blocks commonly is rotated backward (reverse slope), forming depressions along which water may accumulate to create small ponds or swampy areas. Trees on these rotated blocks may be inclined upslope, toward the top of the hill. The lower, downslope end (toe) of a rotational slump is a fan-shaped, bulging mass of material characterized by radial ridges and cracks. Trees on this portion of the landslide may be inclined at strange angles, giving rise to the descriptive terms "drunken" or "staggering" forest. Rotational slumps may develop comparatively slowly and commonly require several months or even years to reach stability; however, on occasion, they may move rapidly, achieving stability in only a few hours.

USGS/Cascades Volcano Observatory, Vancouver, Washington REPORT: Real-time Monitoring of Active Landslides Along Highway 50, El Dorado County, California Mark E. Reid, and Richard G. LaHusen, 1998, Real-time Monitoring of Active Landslides Along Highway 50, El Dorado County: adapted from: California Geology, v.51, n.3, p.17-20 Late in the rainy evening of January 24, 1997, tons of earth gave way down a steep Sierra Nevada canyon slope and slid onto a major northern California highway. The since-named Mill Creek landslide closed U. S. Highway 50 and briefly dammed (5 hours) the nearby South Fork of the American River, about 25 miles east of Placerville (Sydnor, 1997). The slide damaged or destroyed three cabins, and waters dammed by the landslide flooded two vehicles on the highway. Fortunately, there were no fatalities and the waters subsided after the river cut through the dam later that night. However, before Highway 50 could be reopened, an estimated 350,000 cubic yards of slide material (35,000 truck loads) had to be removed over a 4-week period, at a cost of $4.5 million (California Department of Transportation, 1997). Indirect economic costs due to highway closure were estimated at more than $1 million per day. Reid and LaHusen, 1998

94. Landslides Geologic Hazards—landslides. landslides are a recurrent menace to waterways and highways and a threat to homes, schools, businesses, and other facilities. http://www.idahogeology.org/Services/GeologicHazards/Landslides/default.htm

Programs and Services Geologic Hazards Landslides "Landslide" is the general term for the slow or rapid movement of a soil and rock mass down a slope, or for the mass itself. It covers a variety of processes and landforms known as rockslide, rockfall, debris flow, liquefaction, slump, earthflow, and mudflow. The Idaho Geological Survey has identified and plotted over 3,000 landslides in the state for the U.S. Geological Survey's national landslide appraisal. Landslides are a recurrent menace to waterways and highways and a threat to homes, schools, businesses, and other facilities. Landslides may be triggered by other geologic hazards such as earthquakes and floods. Factors of weather and climate, like melting snow and rain that increase the water content of earth materials, may fuel slope instability. The activities of urban and rural living with excavations, roads, drainage ways, landscape watering, logging, and agricultural irrigation may also disturb the solidity of landforms. Late spring-early summer is slide season, particularly after days and weeks of greater than normal precipitation. Landslides are costly. One nightmare for Idaho is maintaining highway U.S. 95, the primary and, in most places, only north-south link from the Canadian border. Redirecting local and through traffic around a landslide is not an option in many places on this heavily traveled road. Alternate routes do not exist, and detours in steep terrain are difficult or impossible to construct. The unimpeded movement over roads
