Abstract

Shallow landslide risk denotes the losses or damages caused by the occurrence of this phenomenon and depends on the magnitude, related to its probability of occurrence, and its effect on the exposed elements, determined by its degree of vulnerability. In this research, a hazard, vulnerability and risk assessment of shallow landslides in a tropical mountainous terrain is carried out. The physical model SHALSTAB was used for the hazard assessment and other models of easy implementation to calculate the physical vulnerability of 8 dwellings and of the people within them. The risk of the structures is calculated, in economic terms, and the risk of loss of human lives, for people inside the dwellings, by means of an analysis of the consequences of these exposed elements given the occurrence of shallow landslides defined in the evaluation of the hazard. This methodology represents a tool that can be useful for land use planning and landslide risk management.
