Mass movements occur in every environment on our planet and represent a significant hazard. This is because of the substantial forces generated by mobile sediment. Landslides result in a considerable social and economic cost, especially in mountainous and less developed countries.
Landslides are triggered by one or more three key factors: precipitation, seismicity and anthropogenic activity. Susceptibility to failure generally develops gradually through long-term landscape evolution processes. The ’causes’ of slope failure include: geological, topographic (strength v’s slope), physical causes (such as elevated groundwater, loss of vegetation) and human causes (mining, construction, logging).
