摘要

Northern Italy (considered as the territory located north of latitude 44° N for this paper; Fig. 1) is situated at the convergence of the northern sector of the Adriatic microplate with the Eurasian plate. It includes the deep (2–8.5 km) sedimentary basin of the Po Plain surrounded by the seismically active structures of the northern Apennines, southern Alps, and northern Dinarides. Present kinematics derived from Global Positioning System measurements (Cenni et al., 2012) indicates a movement of the central–eastern sector in the northeast direction toward the Eurasian plate at a rate of a few millimeters per year, which results in a mainly compressive tectonic style. The area is characterized by moderate–strong seismicity, with five M_w >6 earthquakes in the last century (Rovida et al., 2011). It contributes in a significant way to the overall seismic risk of the country because it is densely populated (231 inhabitants per km~2, or about 28 million in total [ISTAT, 2012]) and has a large number of economically important activities.
