 In addition to shallow erosion or reduction of shear strength caused by seasonal rainfall, landslides may be triggered by anthropic activities, such as adding excessive weight above the slope, digging at mid-slope or at the foot of the slope.Often, individual phenomenon join together to generate instability over time, which often does not allow a reconstruction of the evolution of a particular landslide.Therefore, landslide hazard mitigation measures are not generally classified according to the phenomenon that might cause a landslide.
