The seismicity of the western and southwestern territory of Romania, called in this paper Banat Seismic Region (BSR) is analyzed for the historical period using a new regional Parameter Earthquakes Catalogue (Oros et al. 2007). The catalogue comprises a number of 709 earthquakes occurred between 1443 and 1970, the 269 of which being new recorded events. The magnitudes/intensities (epicentral or maximum observed) range between 2.2 and 5.7 (
, MLH or
) and 3.0–8 EMS, respectively. Some of the major events re-evaluated on instrumental basis (historical seismograms collected by the author as partner into the EuroSeismos project) show larger values of magnitudes than the previous ones. The space distribution of the epicenters displays an obvious clustering trend well correlated with the tectonics and geology (faults and fault systems, structures). The time distribution displays an apparent migration of the seismic activity between different sources zones, e.g. before 1900 the activity concentrates within the northwestern and southeastern areas of BSR and after 1900 the activity groups mainly in the central part of the region.
