The term landslide or, less frequently, landslip, refers to several forms of mass wasting that include a wide range of ground movements, such as rockfalls, deep- seated slope failures, mudflows and debris flows landslides can occur underwater, in which case they are called submarine an avalanche, similar in mechanism to a landslide, involves a large amount.
