ABSTRACT
The distribution of epicenters and the focal mechanism of earthquakes are the basic tools in the determination of the regional stresses in a region. The Mediterranean basin is located at the plate boundary between the Eurasian and African plates. This boundary is of a complex nature and its dynamics is related to the opening of the Atlantic ocean and the closing of the Thetys sea. From Azores to Gibraltar the motion changes from strike-slip to reverse faulting under horizontal compression in NW-SE direction. From Gibraltar to the Caucasus, the boundary is complicated by the presence of secondary blocks, areas of extended deformation and subduction zones. The regional stresses show predominant horizontal compressions in a general NW-SE direction with some isolated areas of horizontal tensions in the Betics-Alboran sea, Apennines and north of the Hellenic arc
