The convergence of the Adriatic Microplate under the Eurasian plate and its counter-clockwise rotation results in a seismically active belt in central and southern Dalmatia, which extends further towards Albania and Greece. The strongest earthquake in the area of Ston-Slano, about 40 km NE of Dubrovnik, occurred on September 5th, 1996 (M = 6.0, Imax = VIII ° MSK) causing substantial material damage in many southern Dalmatian settlements. This thesis is focused on Mesozoic deposits ranginge in age from the Upper Triassic to the Upper Cretaceous, mainly built of limestones and dolomites, Paleogene–Neogene carbonate-clastic deposits and Quaternary unconsolidated clastic deposits. In order to interpret the structural architecture of the studied part of southern Dalmatia, five parallel geological profiles were constructed, perpendicular to the NW–SE striking Dinaric structures. Compression tectonics resulted in fold-thrust belt in which fault-bend and fault-propagation types of foldes are dominant, as well as a system of reverse and thrust faults, with dip angles between 30° and 50°. The surface areas of the interpreted fault planes range from 22.83 to 1692.05 km2. Using of Petroleum Expert Move software for the constructed 3D geological model enabled the visualization and interpretation of the complex geometry of subsurface structures. The geometric parameters of the faults show that the empirically calculated values of the earthquake magnitudes range from 5.55 to 7.24 according to Richter, and thus the interpreted faults represent a significant seismic risk and hazard in the area of southern Dalmatia.
