Evaluating dynamic behaviour of historical buildings through ambient seismic noise measurement and numerical modelling

The paper describes integrated geophysical investigations coupled with structural analysis and numerical simulation with the aim of study and evaluate seismic vulnerability of cultural heritage sites. The analysis consists in collecting data with noninvasive portable instruments to characterize local site effects as well as dynamic properties of the structure. We focus investigations on data collected at several locations in the Maltese Archipelago (central Mediterranean) and in some historical buildings located in Catania (Sicily).
