Abstract

Several natural hazards have been synthesized in one map to obtain an overall assessment of these phenomena. Space and time coherent data have been searched for: minimum disaggregation available was the province and matching year 2007. Two indices of susceptibility have been calculated for fires and landslides; for seismic hazard the median value of provincial values of maximum ground acceleration has been used. For each index, provinces have been classified in four quantile levels. A weighted average of the three classified levels has been calculated with weights proportional to annual expenditure for every type of event. Results are meaningful at ordinal scale and cannot be interpreted as a measure of risk. Floods and volcanoes have been mapped, too, thus obtaining a global overview of the main natural hazards in Italy
