field of forces (stress is a force per unit area) which is active on a mass of rock or soil on the slope. Basically, the two main determinative parameters are: • An increase of shear stress. • A decrease of material strength. Page 6. Landslide types and causes. 6. Increase in shear strength. 0 Removal of lateral and underlying
TYPES OF LANDSLIDES. Landslides can occur as flows, slides, or rockfalls and topples. A major difference between the three types is the amount of water—flows have the most and rockfalls usually have the least. FLOWS. Flows are generally a slurry mixture of water, soil, rock and (or) debris that moves rapidly downslope.
occurrence and potential are the coastal and mountainous areas of California, Oregon, and Washington, the States comprising the intermountain west, and the mountainous and hilly regions of the Eastern United States. Alaska and Hawaii also experience all types of landslides. Landslides in the United States cause
VARNES? CLASSIFICATION OF SLOPE MOVEMENTS www.ukgeohazards.info/pages/eng_geol/landslide_geohazard/eng_geol_landslides_classification.htm. The landslide classification based on Varnes' (1978) system has two terms: - the first term describes the material type,. - the second term describes the type of
Earthflows range from very small to the very big, involving hundreds of tons of material blocking or destroying roads, damming rivers and destroying houses. DEBRIS FLOW OR MUDFLOW. These two terms are used interchangeably and they refer to the rapid but viscous flow of mud and other surficial materials. Rotational
Full-text (PDF) | In the initial reconnaissance of a landslide, the activity and the materials displaced in that type of landslide would be described using terms from Table 3-2, the dimensions defined in Table 3-4 would be estimated, and some preliminary hypotheses would be chosen about the causes
26 Jul 2013 action brought on by changes in temperature. (expansion and shrinkage), the freeze-thaw cycle, and the burrowing activity of animals. Earthquakes. Earthquakes not only trigger landslides, but, over time, the tectonic activity causing them can create steep and potentially unstable slopes.
26 Jul 2013 Causes and Types of Landslides. What is a Landslide? The term "landslide" is used to describe a wide variety of processes that result in the percept- ible downward and outward movement of soil, rock, and vegetation under gravitational influ- ence. The materials may move by: falling, top- pling, sliding
Interactive events that occur in sequence may produce cumulative effects that are significantly different from those expected from any single event. . TyPES OF LANDSLIDES AND. SLOPE FAILuRES: Slump: Type of slope failure in which a downward and outward rotational movement of rock or soil occurs along a curved.
Landslide Types and Processes. David J. Varnes3. It is the purpose of this chapter to re- view the whole range of earth move- ments that may properly be regarded as landslides and to classify these move- ments according to factors that have some bearing on prevention or control. As defined for use in this volume the.
