Sažetak
During the ten-year period from 2006 to 2015 a total of 34391 earthquakes were located in Croatia and its surrounding areas, with 37 main events registering magnitudes from 4.0 to 4.9. Seismically the most active was the coastal part of Croatia confined to two seismically distinguished areas. The NW domain was seismically less active, with about 10000 events (seven were of magnitude ML>=4.0), among which were the three strongest events that occurred in Croatia during the observed period. Two of them occurred in the Senj epicentral area, the first one on 5 February 2007 at 8:30 (ML = 4.9, Imax = VII °MSK) and the second one on 30 July 2013 at 12:58, (ML = 4.8, Imax = VI °MSK). The third event occurred near Kornati Island on 18 July 2007 at 10:54 (ML = 4.8). The SE domain experienced the highest number of earthquakes (almost 18000 events, with 24 events of magnitude ML>=4.0, among which the strongest one was of magnitude ML = 4.9 with the epicentre in Bosnia and Herzegovina near the Croatian border). The seismicity in the continental part of Croatia was weak-to- moderate during the observed period, with earthquakes of magnitudes ML ≤ 4.1. Focal mechanisms were obtained for 31 earthquakes with magnitudes ML >= 4.0 recorded in Croatia, and individual earthquakes have also been macroseismically analysed. Both regions (continental and coastal) are in the stress accumulation phase and they seem to be close to reaching the critical strain level.
