The risk resulting from natural hazards can be derived from the combination of parameters of physical processes and the damage potential. Even though the damage potential has been taken into account more frequently, quantifying statements are still missing. This study presents a detailed recording of the damage potential in the study area and describes the development of the damage potential since 1950 in decades. In the community, the increase of the number of buildings and their values is above average of the region. 37% of the existing buildings are located in legally declared avalanche hazard zones. In these areas, the probability of presence of persons increased considerably due to tourism activities and shows substantial seasonal fluctuations. If the analysis of the damage potential and the hazard estimation are performed with the same degree of precision, risk analysis and risk management will be improved significantly.
