Document Summary
Trains and railroads allowed people easy access into the mountains for the first time which greatly increased populations living in the mountains. It plays a crucial role in creating them as hazards. Allo(cid:363)s people i(cid:290)to places that (cid:363)e should(cid:290)"t be. Allows us also to modify slopes, vegetation, and moisture in such a way to increase the likelihood of slides occurring. It occurred in the loess terrain where people have been carving homes. The haiyuan earthquake was the deadliest landslide in history. These homes are vulnerable so almost all died. Occurred at the same time as the north china famine so it was relatively quiet. Landslides and mass wasting occur because slopes exist and gravity works. For any material along a slope, there is a balance between driving and resisting forces.

Any slope at all can have mass movement.
