Human activity and the stability of slopes
Strategies to modify slopes to reduce mass movement:
Pinning: Used to attach wire nets or sometimes concrete blocks to a rock face or slope so that the risk is reduced.
Netting: may help collect fragments of scree, which can be safely removed at a later date. Used in areas that tourism is important and the risk of rock fall is high.
Grading: re-profiling slopes so that they become more stable. Afforestation is the planting of new forest in upper parts of a catchment to increase interception.

Local erosion
Footpath trampling
Dumping waste soil and rock unstably that move without warning

Urban areas
Slope modification is often very high due to the need of buildings and roads
Slope modification tends to increase as a construction moves on to steeper slopes.
The steep slopes that are devoid of soil and vegetation are potentially less stable that a natural slope and in times of intense rainfall, they are prone to small but very damaging landslips.
