Less dramatic types of downslope movement move earth materials slowly down a hillside. Slump moves materials as a large block along a curved surface (figure 1). Slumps often happen when a slope is undercut, with no support for the overlying materials, or when too much weight is added to an unstable slope. Figure 1.Mar 20, 2019 · The Oso landslide, also known as the SR 530 landslide, occurred in northwest Washington state on March 22, 2014, leading to devastating loss of life and destruction of property. Landslide debris blocked the North Fork Stillaguamish River, destroyed about 40 homes and other structures, and buried nearly a mile of State Route 530.

The landslide at Pretty Rocks has been active since at least the 1960s, but has evolved from a manageable maintenance concern into a much more extensive maintenance challenge. Before 2014, the landslide only caused small cracks in the road surface and required maintenance every 2-3 years. Between 2016 and 2017, the full width of a 100-yard (90 ...Slump, in geology, downward intermittent movement of rock debris, usually the consequence of removal of buttressing earth at the foot of a slope of unconsolidated material. It commonly involves a shear plane on which a back-tilting of the top of the slumped mass occurs. The plane is slightly

Those slumps consisting of two or more single slump bodies are defined as landslide complexes. 4.2.3. Landslide complexes. Landslide complexes consist of lateral and vertical superposition of multiple landslide bodies (Figure 8, Figure 9, Figure 10). Two or more glide surfaces usually occur in a landslide complex.The removed mass of soil and rock leave an abrupt drop-off at the top of the landslide known as a scarp. Repeated slumping can often result in terracing, or a series of scarps, as secondary failures occur within the landslide mass. Above: Schematic of slump. Image courtesy of Maine Geological Survey.

TYPES OF LANDSLIDES The term "landslide" describes a wide variety of processes that result in the downward and outward movement of slope-forming materials including rock, soil, artificial fill, or a combination of these.An example of a slow-moving slump is the Swift Creek Landslide, a deep-seated rotational slump located on Sumas Mountain, Washington. Slumps may also occur underwater along the margins of continents and islands, resulting from tidal action or a large seismic event. These submarine slumps can generate disastrous tsunamis.

An earthflow is best described as. A cohesive soil flow made up of mostly fine grained sediments (e.g., silt, clay and sand) that is triggered by intense rainfall or rapid snow melt.A slump is a form of mass wasting that occurs when a coherent mass of loosely consolidated materials or a rock layer moves a short distance down a slope. Movement is characterized by sliding along a concave-upward or planar surface. Causes of slumping include earthquake shocks, thorough wetting, freezing and thawing, undercutting, and loading of a slope. Seismic-reflection data and historical accounts suggest that a large submarine slump in the Dead Sea was produced by the most recent large earthquake along the Dead Sea-Jordan transform plate boundary, the M L 6.25 Jericho earthquake of July 11, 1927.

Rotational Slide (Slump): A rotational slide is a type of landslide movement that occurs in a turning moment, about a pivot point that is above the center of gravity. This is typically due to an increased normal force on a slope, as well as a reduced cohesion factor of the soil mass materials. Additionally, the slip surface is concave, upwards.

The 1995 landslide was a deep, coherent slump—earth flow that deformed plastically and moved slowly enough that people could get out of its way. The 2005 landslide was a shallower remobilization of the very same material into a rapid, highly fluid debris flow that buried 10 people.likelihood of a landslide.

In rotational landslides, the toe is often a large, disturbed mound of geologic material, forming as the landslide moves past its original rupture surface. Rotational and translational landslides often have extensional cracks, sag ponds, hummocky terrain, and pressure ridges.

As you saw in Exercise 15.1, when a mass of sediment becomes completely saturated with water, the mass loses strength, to the extent that the grains are pushed apart, and it will flow, even on a gentle slope.

It is faster. Creep is involved upto shallow depth (app. 1-2 m), whereas the rapid flow is involved to greater depth (app. upto 5 m or more) Landslides If a mass of earth moves along a definite plane or surface the failure is termed as Landslide Large block known as a slump block moves during the landslide.An example of a slow-moving slump is the Swift Creek Landslide, a deep-seated rotational slump located on Sumas Mountain, Washington.
