Like other natural hazards, landslides can be characterized by their intensity. Intensity can be defined as a set of quantitative or qualitative spatially distributed parameters, which determine the potential of a given landslide phenomenon to cause damage. Depending on the type of landslide, intensity parameters may include movement velocity and depth, deposit thickness, impact pressures, depth of erosion, differential movements, or strain. Intensity is connected with its own probability values, which can be lower than the probability of occurrence of the landslide. Determination of potential intensity is an intermediate step in landslide risk mapping. It provides a convenient junction point between the hazard assessment stage, carried out primarily by a geoscience professional and the risk assessment stage which should have input from other interested parties.
