Answer:
Landslides can be initiated in slopes already on the verge of movement by rainfall, snowmelt, changes in water level, stream erosion, changes in ground water, earthquakes, volcanic activity, disturbance by human activities, or any combination of these factors.
Mitigation measures for fall landslides can include installing protective covers such as metal meshes over the sensitive zone, blasting with explosives of hazardous zones, or the removal of materials from such, anchoring of cliffs with rock bolts, and scaling
