The purpose of this study consists in the evaluation of completeness magnitude (Mc), b value spatial variation and seismic energy release in Vrancea crustal seismogenic area, during the period between 1990 and 2021. This parameters are essential for a correct interpretation of seismicity analysis. For the analyses, we have selected from the Romplus seismic catalog (www.infp.ro) the crustal events with depth 0<h<52 Km, and magnitudes 0.1 <Mw <5.4,recorded from 01 January 1990 to 01 March 2021, in the area bordered ...

The purpose of this work consists in analyses of declustering catalogue and seismic sequence recorded in Vrancea crustal area . The moderate-size earthquake with local magnitude 5,7 which occurred on November 22, 2014 in Vrancea region, at 41 km depth, is the largest crustal event instrumentally recorded at the bending of the Eastern Carpathians. The crust seismicity in front of the Carpathian Arc spreads to the East, in a strip delimited by the Peceneaga-Camena fault, to the North and East, and to the South is lo...

The moderate-size earthquake with local magnitude 5,7 which occurred on November 22, 2014 in Vrancea region, at 41 km depth, is the largest crustal event instrumentally recorded at the bending of the Eastern Carpathians. Using the method developed by [2] termed the Hash method, (incorporated in Seisan software) we obtain the focal mechanisms for earthquakes that occurred in Vrancea region associated with the seismic sequence of November 22, 2014. We have examined the main shock and 29 aftershocks that occurred aft...
