ABSTRACT
The study area is located at the contact between the Apuseni Mountains (Western Carpathians) with Pannonian Depression-to the west and with Transylvanian Depression - to the east. The eastern limit is marked by the Eastern Carpathians. The current tectonic activity is manifested by an uplift of the Carpathian Orogeny in relation to neighboring units, particularly the Pannonian Depression. The main seismological active areas are on the edge of the Pannonian Basin and in contact with the basement of Apuseni Mountains and Eastern Carpathians. Historical data suggests two potential earthquake magnitudes Mw >6, one of magnitude 6.2 (Mw) and one with magnitude 6 (Mw). Generally, the characteristics earthquakes of the area have magnitude Mw≤5.6. We expect that the horizontal components of the movement (generated by the uplift of the Carpathians) to produce a compressive stress, as shown by focal mechanism solutions.
