Abstract

The events of the seismic sequence of Central Italy (the first of which occurred on the 24th of August 2016 and the last on the 18th of January 2017) induced severe damages in a very large area, involving the regions of Lazio, Umbria, Marche and Abruzzi. Part 1 of this work discussed and analysed damages occurred to ordinary masonry buildings, which constitute the majority of the building stock in the affected area. This part 2 presents a series of case studies of urban centres affected by the earthquakes of this sequence, highlighting the different characteristics of the buildings and their effects on the observed damage. In particular, a better performance was observed for buildings located in centres that were recently affected by previous events, in which antiseismic devices are quite systematically present (as for example in the case of Norcia). This is not the case for other municipalities, in which the building stock is characterized by a higher vulnerability, with the consequences that are unfortunately known to everybody, despite the fact that the seismic classification of these areas dates back even to more than 100 years ago.
