Week four geog 1350 earth: hazards and global change january 30th. Landslides the downslope movement of earth material, constitute a serious natural hazard in many parts of the world. Most landslides are small and slow, but some are large and fast. Both may cause significant loss of life and damage of property particularly within urban areas. The fra(cid:374)k slide is ca(cid:374)ada"s (cid:271)est-known landslide and was been subject to many geologists: factors that came into play geology, glaciation, mining and weather. Trigger an event that sets off the landslide, which can also be considered the final straw. Landslides and mass wasting are used to describe the downslope movement of rock/sediment: the mechanism of movement (fall, topple, slide, flow), the type of material (rock, consolidated sediment, organic soil), the amount of water present, rate of movement. Fall bounding of rock or blocks of sediment from the face of the cliff.
