What actions can be taken to prevent landslides?
There are many ways to reduce the potential for landsliding. This can involve preventing new landslides or re-activation of pre-existing landslides. One of the most important steps to take is to understand the structure of the bedrock (assuming we are talking about a bedrock landslide). Geologic mapping or drilling can reveal the type of bedrock and the orientation of the discontinuities (eg. bedding planes, previous rupture surface). Mainly those slopes that have bedding tilted the same direction as the sloping hillside surface and that are tilted at an angle less than the hill slope angle are likely to generate unstable conditions. From that point there are several measures you can take including: Removal of material from the upslope portions of the unstable areas (to reduce the mass that would provide a driving force). Placement of soil/dirt at the base of the unstable slope to act as a buttress (adding mass to create a resisting force) Reduce the amount of surface water that can pe
