Triggers for mass wasting can be divided into passive and activating (initiating) causes. Passive causes include: • Rock and soil lithology. Unconsolidated or weak debris are more susceptible to mass wasting, as are materials that lose cohesion when wetted. • Stratigraphy, such as thinly bedded rock or alternating beds of weak and strong or impermeable or permiable rock lithologies. WebTriggers of mass wasting events may include Intense rainfall Mass wasting is sometimes triggered when heavy rains or periods of snowmelt saturate surface materials. This was the case in October 1998 when torrential rains associated with Hurricane Mitch triggered devastating debris flows in Central America.
