Fault plane solutions for 128 earthquakes registered by the modern national seismological network of Bulgaria are presented. Geodynamic analysis is performed and some correlations with other geological, geophysical and geodetic results are analyzed. The obtained prevail extensional stresses in Bulgarian territory are explained by two regional geodynamic processes. The first is the post-collisional extensional collapse of orogens under the influence of the paleosubduction in the Ionian sea towards the Bulgarian territory. The second process is the complex influence of the existing SW horizontal movements along the North Anatolia fault in the Aegean Sea, which causes the extension of the eastern parts of the Bulgarian lands and formation of an extensional province towards north from the North Aegean Trough.
