In this perspective, the seismic vulnerability of existing bu ildings, which can be assessed with the probability of exceeding a certain damage threshold depending on a seismic input, is still a very open topic. In the present work, a preliminary analysis was conducted on the damage observed following the 2016 Central Italy seismic sequence, collected in the AeDES forms. The observed damage was converted into five damage levels, according to the European Macroseismic Scale (EMS-98). Information on undamaged buildings was gathered from census data. Based on the sample of buildings obtained, the main taxonomies were defined. Furthermore, for the various events of the seismic sequence, the ground motion intensity at the base of each building was calculated, and Damage Probability Matrices were defined. This work represents the first step in a study aimed to develop seismic vulnerability models for existing buildings in central Italy, based on the damage observed in these areas.
