        Recent examples of Arizona landslides, debris flows and rockfall US Route 89 Landslide, February On 20 February , a landslide along the Echo Cliffs south of Page, Arizona, sliced through several hundred feet of US Ro causing the Arizona Dept. of Transportation (ADOT) to close the mile section of road between Bitter Springs. We measured displacement, pore-water pressure, and climatic conditions for 3 years at the continuously moving Slumgullion landslide in Colorado, USA. The landslide accelerated when pore-water pressure increased within the landslide body, but this occurred as pore-water pressure decreased along the landslide margin. The decrease probably occurred in response to shear-induced soil dilation at.

      Landslides and Mudslides. Landslides occur when masses of rock, earth or debris move down a slope. Mudslides, also known as debris flows or mudflows, are a common type of fast-moving landslide that tends to flow in channels.

      While earthquakes regularly trigger landslides, the gigantic landslide the night of Ap , is the first known to have triggered quakes. The slide occurred in the form of two huge rock avalanches at p.m. and p.m. MDT at Rio Tinto-Kennecott Utah Copper’s open-pit Bingham Canyon Mine, 20 miles southwest of downtown Salt Lake.   A Utah mountainside collapsed 4, years ago in a gargantuan landslide known as a “rock avalanche,” creating the flat floor of what is now Zion National Park by damming the Virgin River to create a lake that existed for years. Those are key conclusions of a new University of Utah .

Witkind. A wide array of landslides occur in Arizona. Ranging from fast-moving debris flows, rockfall, and topple to slow-moving creep, and from larger volume rotational landslides and debris avalanches to smaller volume earthflow. Landslides result from disturbances in the natural stability of a slope.

The occurrence of debris flows during the September northern Colorado floods took the emergency management community by surprise.

The September debris flows in the Colorado Front Range initiated from shallow landslides in colluvium. Most occurred on south- and east-facing slopes on the walls of steep canyons in crystalline rocks and on.

Landslides routinely claim lives, killing more t people from to globally, not including earthquake-triggered landslides. However, the Bingham Canyon rockslide resulted in no. The lower slopes of the Wasatch Range above Farmington were burned in the July Farmington fire.

Following the fire, the Utah Geological Survey (UGS) assessed the heightened fire-related debris-flow hazard and produced a map showing debris basins and areas of possible flooding and debris flows.

The geology of 36 km² in Ephraim Canyon, on the west side of the Wasatch Plateau, central Utah, was mapped at a scale offollowing the occurrence of numerous landslides in Although some landslides require lengthy rain and saturated slopes, a debris flow can start on a dry slope after only a few minutes of intense rain, like Arizona’s monsoons.

“Intense” rain means a burst of rain at a fast rate, about half an inch in an hour. With debris flows. Landslides and Debris Flow (13) Utah Geological Association (36) Geologic Maps.

Landslides and debris flows in Ephraim Canyon, central Utah Bulletin C By: Rex L. Baum and Robert W. Fleming. Landslides, mud flows, debris flows, and rockfalls are among many geologic and soil hazards that impact Colorado. Landslides are the downward and outward movement of slopes composed of natural rock, soils, artificial fills, or combinations names for landslide types include slump, rockslide, debris slide, lateral spreading, debris avalanche, earth flow, and soil creep (Colorado.

slide, and flow. Typical landslides in Utah include slides, rock falls, debris flows, and earth flows. In Utah, many landslides move slowly, but some move quickly with devastating results. Debris flows, which are a type of landslide having very high water content, can travel at speeds greater than 30 to 50 miles per hour.

Causes of Landslides. Information about landslides and landslide mapping. Diagram by J. Appleby, R. Kilbourne, and C. Wills after Varnes, A debris slide is a landslide of coarse-grained soil, most common in unconsolidated sandy or gravelly units, but also are common in residual soils that form from in-place weathering of relatively hard rock.

Figure 2F-1 Three Common Types of Landslides in Utah Debris flows consist of sediment-water mixtures that flow down a streambed or hillside, commonly depositing sediment at canyon mouths in fan like deposits known as alluvial fans.

Slides are down slope movements of soil or rock on slopes. Rock falls consist of rock(s) falling from a cliff or.The Bingham Canyon Mine is one of the largest open-pit mines in the world, measuring more than 4 kilometers ( miles) wide and 1, meters (3, feet) deep.

Although the likeli-hood of debris flows begins to decline after a day or more of dry weather, deeper, generally slow-moving landslides can occur days, weeks, or months after a period of prolonged rainfall has ended. Deep-Seated Landslides Although much of the water from prolonged rainfall runs off.
