MAIN ACTIVE FAULTS FOR 5.6 (Mw) MEHADIA EARTHQUAKE, 4.1 (Mw) WEST TEREGOVA EARTHQUAKE, 4.1 (Mw)) MOLDOVA NOUA EARTHQUAKE AND 4.3 HATEG EARTHQUAKE, FROM DACIA TECTONIC UNIT

The current tectonic structure of the southern part of the Southern Carpathians, nearby Danube, is the combined result of a main northward translation movement and a secondary right-lateral rotation of the tectonic units from their Mesozoic position to their current position during the Paleogene-Neogene period. The main fault system in the region is the South Carpathian Fault System, which characterizes the basement and orogenic structures and delineates the major geotectonic units. The faults within this system are either thrust faults (Sichevița-Retezat) or trans-crustal vertical faults (Oravița-Moldova Nouă). The faults of the South Carpathian System are predominantly oriented NE-SW (Cerna Jiu Fault), except for the Bistrița Fault and the West Teregova Fault, which are oriented E-W. To the west, the South Carpathian Fault System interacts with another significant fault system, the Pannonian Fault System. This system controls the neotectonic activity in the region, exhibiting predominant NNE-SSW directions (Hateg-Sarmisegetusa Fault).
