4. Conclusion In the present paper, seismic risk assessment at urban level of historical center of Cosenza (South of Italy), is analysed and described. The analysis has been varied out through a simplified method proposed by Bacci et al. (2018, 2019) allowing to obtain through basic information deduced by dataset and surveys, seismic risk level of a specific compartment or of the whole city. In the specific, the seismic risk is expressed through an index that is given by the sum of index dependent by exposure, hazard and vulnerability. In this work, information about hazard, vulnerability and exposure were deduced essentially by National Dataset [ISTAT (2019)]. From the study, it is deduced that being Cosenza historical center characterized by a lot of disordered masonry buildings very close to each other (which influences exposure and vulnerability) and with an average number of floors equal to four, with a high seismic hazard level, the risk class is high and equal to 4. This study is a first step in assessing the seismic risk of the historical center of Cosenza, which will be further investigated with additional data and more refined methods.
