A slump is a type of mass wasting that results in the sliding of coherent rock materials along a curved surface. In a slump, a portion of the mountain moves down a short...
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.
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.

It’s important to classify slope failures so that we can understand what causes them and learn how to mitigate their effects.
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.
Jan 1, 2016 · Slides and rotational slides (slumps) include downward and horizontal displacement of rigid or semi-rigid masses of soil (earth and debris), or rock under the influence of gravity. This includes movements of land and the sea bottom. It differs from a collapse where displacement is entirely vertical.
Quick Reference. A form of mass movement (also called a single rotational slide) where rock and soil rotate backwards with movement down a concave face: ‘a more or less rotational movement, about an axis that is parallel to the slope contours, involving shear displacement along a concavely up-ward facing failure surface’ (D. Varnes1978).
