Remember Rotational Slide
Rotational Slide Technical Terms
Rotational Slide: The process, associated sediments (rotational landslide deposit) or resultant landforms characterized by an extremely slow to moderately rapid type of slide, composed of comparatively dry and largely soil-rock materials, 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. The landform may be single, successive (repeated up and down slope), or multiple (as the number of slide components increase). Compare – rotational debris slide, rotational earth slide, rotational rock slide, translational slide, lateral spread, landslide. SW & DV
