A procedure for quantitative landslide risk mapping considering both hazard and vulnerability is presented. The approach has been applied in a municipality in the lower Deva valley (Spain). Firstly, a susceptibility model has been elaborated on the basis of the statistical relationships between past landslides and terrain parameters related to instability. From the analysis of landslide frequency (for the last 50 years) and magnitude, the susceptibility model has been transformed into a probabilistic hazard model for a stated period (spatial-temporal probability of new landslides in any point of the study area). On the other hand, a detailed inventory of direct damages due to landslides during the study period has been carried out. Then vulnerability has been assessed by comparing losses with actual values, for specific scenarios. The combination of hazard (probability) and vulnerability (0-1) have provided a quantitative risk map, in which potential losses are expressed in monetary terms (?/pixel/year).
