Structural architecture and kinematic properties of faults in the Dubrovnik area and its hinterland (Croatia, Bosnia and Herzegovina, Montenegro)

Dalmatia is considered as one of the three tectonically most active regions in Croatia, characterized by moderate to strong seismicity with several instrumentally recorded earthquakes of Mw6. Identification of potential seismogenic sources and their detailed segmentation within epicentral areas is of great importance in seismic hazard and risk assessment procedure. Results of structural modelling with associated depths and faults geometrical relations as well as a seismological data indicate fault-related fold structure that accommodated vertical displacement more than 3500 m. Furthermore, faults geometrical peculiarities suggest complex tectonic history associated with presence of Triassic ductile deposits resulting with complex seismogenic source geometry alongside associated distribution of hypocenters. Based on the 3D modelling, empirical computations of identified fault segments maximal magnitudes are estimated in a range between Mw 6.29-7.53.
