In geology, a slump forms a mass of loosely consolidated material or a rock layer moves a short distance down a slope. The movement is characterized by sliding along a concave-upward or planar surface. Based on other HiRISE images, this particular slump occurred between 9 March 2020 and 17 February 2021, corresponding to the relatively warm spring and summer of the Southern Hemisphere. This is among the largest active slumps documented on Mars, about 700 meters (0.4 mile) long. Causes of slumping on Earth include earthquake shocks, reduction of friction through wetting, freezing and thawing,…
