Mass wasting events are caused by gravity in combination with a variety of geologic, climatic, and in some cases human factors. One other factor which is often associated with dramatic mass wasting events is vegetative cover and particularly sudden changes to vegetative cover by fire or human activities.ometimes large mass wasting events (or large numbers of smaller events) are associated with heavy rains. Heavy precipitation can initiate certain types of mass wasting by creating hydrostatic pressure and serve to lubricate slides once they are in motion.
