rotational debris slide

rotational debris slide
   The mass movement process, associated sediments (rotational debris slide deposit), or resultant landform characterized by an extremely slow to moderately rapid type of slide, composed of comparatively dry and largely unconsolidated earthy material, portions of which remain largely intact and in which movement occurs along a well-defined, concave shear surface and resulting in a backward rotation of the displaced mass; sediments have substantial proportions of both fine earth and rock fragments. The landform may be single, successive (repeated up and down slope), or multiple (as the number of slide components increase).
