Abstract
The risk due to natural hazards is usually assessed in physical terms by estimating the losses they may cause. Nevertheless, the risk assessment can involve other aspects like the lack of economic and social development, management deficiencies and inability of the society to respond and recover in case of a hazard event. In this chapter, the case study of Barcelona is described. The seismic risk of the city is first studied by considering a probabilistic model of the hazard and risk. By means of the risk evaluation model CAPRA (Comprehensive Approach to Probabilistic Risk Assessment) the potential losses on exposed elements are evaluated using probabilistic metrics, such as the loss exceedance curve, the expected annual loss and the probable maximum loss. Based on the obtained results, a holistic evaluation of risk is performed taking into account social fragility and lack of resilience aspects. Finally, an evaluation of the disaster risk management performance is conducted.
