  2. Slump (geology) - Wikipedia

    en.wikipedia.org/wiki/Slump_(geology)

    A rotational slump occurs when a slump block, composed of sediment or rock, slides along a concave-upward slip surface with rotation about an axis parallel to the slope. [3] Rotational movement causes the original surface of the block to become less steep, and the top of the slump is rotated backward.

  3. Landslide classification - Wikipedia

    en.wikipedia.org/wiki/Landslide_classification

    For example, the distinction between earth and debris is usually made by comparing the percentage of coarse grain size fractions. If the weight of the particles with a diameter greater than 2 mm is less than 20%, the material will be defined as earth ; in the opposite case, it is debris .

  4. Hilina Slump - Wikipedia

    en.wikipedia.org/wiki/Hilina_Slump

    The Hilina Pali is the headscarp of the Hilina Slump, a type of landslide where a large and relatively intact block slips along a concave surface, dropping vertically at the head, with the toe often extending upward as well as outward [22] The Hilina Slump extends seaward from both ends of the Hilina Pali out to a depth of 5,000 meters (16,404 ...

  5. Landslide - Wikipedia

    en.wikipedia.org/wiki/Landslide

    In traditional usage, the term landslide has at one time or another been used to cover almost all forms of mass movement of rocks and regolith at the Earth's surface. In 1978, geologist David Varnes noted this imprecise usage and proposed a new, much tighter scheme for the classification of mass movements and subsidence processes. [ 26 ]

  6. Retrogressive thaw slump - Wikipedia

    en.wikipedia.org/wiki/Retrogressive_thaw_slump

    The retrogressive thaw slump forms on massive ice or ice-rich permafrost, which is often covered in a layer of tundra vegetation under which a layer of peat may lie. [9] The RTS surface is convex and is located on the shoulder of the hillslope. [10] The most thawing occurs on south- and west-facing slopes. [11]

Mass wasting, also known as mass movement, [1] is a general term for the movement of rock or soil down slopes under the force of gravity.

    en.wikipedia.org/wiki/Batagaika_crater

    According to a conference paper published in 2016 [7] the crater did not show any signs of stabilization after several decades (since 1980s) of slump growth, with the headwall retreating with observed rates of generally >10 m and up to 30 m per year closer to 2016. Reconstruction of a paleo-surface revealed that the slump had carved at the time ...
