Abstract

Natural disasters may be powerful and prominent mechanisms of direct or indirect release of hazardous material. The main aim of this work was to develop a short-cut methodology for assessing the vulnerability of a territory around an industrial plant in order to evaluate the Natural???Technological (NaTech) risk. In particular the combined use of a global key hazard indicator with the key vulnerability indicator proposed in this work allows the measurement of the NaTech risk arising from the presence of a plant in a territory with given characteristics. The proposed methodology was validated by comparing its results with quantitative risk analysis (QRA) results, involving earthquake-related NaTech events. The agreement of the results obtained with the proposed methodology with those arising from a much more detailed \{QRA\} carried out with the ARIPAR-GIS software in several case study supports the reliability of the proposed approach.
