Abstract
The main goal of this study is to investigate the dynamic properties of main lithotypes outcropping on the island of Malta and to evaluate the general features of the local seismic response through the combined use of geophysical methods based on Rayleigh waves and horizontal to vertical noise spectral ratios. These kind of studies have unfortunately never been undertaken in Malta and, therefore, no shear wave velocity values and fundamental frequency of outcropping lithotypes have been published. The proposed preliminary results represent a valid set of data useful for evaluating seismic hazard and risk for the Maltese islands. Even if the seismic activity around the archipelago is generally of low to moderate magnitude the islands in the past were struck by large events in Sicily and the Hellenic arc resulting in considerable damage.
