This paper describes the methodology followed to derive typological seismic risk maps for Italy and then presents the results. In its classical definition, seismic risk is obtained from the convolution of hazard, vulnerability and exposure. Due to the absence of reliable data on exposure for the entire Italian territory, this study proposes typological seismic risk maps, obtained by simply convolving hazard and vulnerability for several building typologies characteristic of the Italian building stock. A specific hazard study in terms of PGA has been carried out. The results have then been convolved with empirical typological fragility curves, that were derived from data collected during post-earthquake surveys after the main Italian events of the last 30 years. Useful applications can be found for the typological seismic risk maps, both for risk mitigation strategies and for purely economical evaluations (e.g., insurance and reinsurance studies).
