Sažetak
The Dinarides, a NW-striking mountain chain along the eastern margin of the Adriatic plate, is the most seismically active zone in Croatia. Historical and instrumental records indicate ongoing tectonics concentrated within southern Dalmatia. Results of the DInSAR analysis of coseismic deformation and fault kinematics for the Ston–Slano 1996 ML 6.0 earthquake are presented. Constructed interferograms suggest concentric fringe pattern of coseismic ground displacements, with maximum uplift of 26 cm and subsidence of c. 8 cm in the Podimoć area, approximately 8 km NW of 1996 Ston–Slano earthquake epicentre. The kinematic analysis of shear joint/fault data indicate compressional/transpressional stress field with NE–SW and locally NW–SE trending SHmax, coinciding with the present stress field. Considering the location of microseismic epicentre, analyzed interferograms and fault kinematics suggest that the earthquake rupture probably started near Slano, and proceeded towards NW along a reverse fault situated in the Adriatic offshore.
