An intense seismic activity started on February, 2023, close to Targu Jiu city, in Gorj region (Romania), as part of the Getic Depression. The earthquakes were located nearby the contact between Getic Depression and the Carpathians orogen. The seismic sequence consisted of more than 3100 foreshocks with the highest magnitude of Mw=4.9 (occurred on 13 February 2023), respectively Mw= 5.4 (on 14 February). A stable and automatic method, implemented and optimized in the real time data acquisition and processing system (ANTELOPE) to estimate in real time the seismic moment, the moment magnitude and the corner frequency of events recorded by the velocity sensors, using spectral analysis applied to S waves. The purpose of this work consists mainly in the estimation of the source parameters (Mw, M0 and f0), combined with ground motion parameters using the velocity network of the NIEP, of more than 70 automatically located seismic events with Mw magnitude between 2.7 and 5.4. The main goals are the independent estimation of the seismic moment and common characterization for all events recorded by the velocity network.
