In geological terms, a landslide refers to the movement of a mass of rock or soil down a slope. This can be caused by factors such as gravity, erosion, or human activity. A slump, on the other hand, is a type of landslide where the movement is rotational and occurs along a curved surface.
Apr 19, 2004 · Using a full-scale simulator, researchers have shown that just a small difference in soil density determines whether a landslide becomes a fast-moving killer or merely one that slowly slumps...

Slope failure can occur due to various natural and human-induced factors. Some of the common causes of slope failure are: 1. Geology and Soil Properties: The type and properties of soil and rock underlying the slope can contribute to instability. For example, slopes with weak or weathered rock, clay soils, or soils with a high water content are mor...
There are several types of landslides, which are classified based on the type of material involved and the way they move. Some of the common types of landslides are: 1. Rockfall: This occurs when rocksor boulders detach from a steep slope and fall to the ground. 2. Rockslide: This occurs when a large block of rock slides downhill along a plane of w...
There are several techniques used for slope stability analysis, including: 1. Limit equilibrium analysis: This method assumes that the slope fails along a failure plane, and the factor of safety is the ratio of the resisting forces to the driving forces along that plane. Different methods can be used for this type of analysis, such as the Bishop’s ...
Slump example: Landslide Occurs in Alta, Norway – Jun. 3, 2020. Landslide sweeps Norway homes into the sea. Watch on. Rock falls are abrupt movements of masses of geologic materials, such as rocks and boulders, that become detached from steep slopes or cliffs.
A landslide is defined as the movement of a mass of rock, debris, or earth down a slope. Landslides are a type of "mass wasting," which denotes any down-slope movement of soil and rock under the direct influence of gravity. The term "landslide" encompasses five modes of slope movement: falls, topples, slides, spreads, and flows.
Jan 1, 2016 · A slump is the name given to a slide when the underlying failure surface is curved rather than planar. The motion of a slump is rotational, so that portions of the slide drop and rise with respect to the adjacent stable slopes. It is more properly referred to as a rotational slide.
May 14, 2018 · Like the term mudslide, slump is frequently used but is not defined in the classification system used by most landslide specialists. Depending on the type of earth material involved, a slump can be properly described as a rock slide, debris slide, or earth slide with predominantly rotational movement.
