"Landslides are aggravated by human activities. Human causes include:deforestation, cultivation and construction, which destabilize the already fragile slopes:
* vibrations from machinery or traffic
* blasting
* earthwork which alters the shape of a slope, or which imposes new loads on an existing slope
* in shallow soils, the removal of deep-rooted vegetation that binds colluvium to bedrock
* Construction, agricultural or forestry activities (logging) which change the amount of water which infiltrates the soil."
