ABSTRACT
During October 2013 a swarm of seismic events originated in the NW Galati area, hence a striking number of earthquakes (a few hundreds), having a magnitude under 4.0 (on the Richter scale), generally associated with the fault system from this seismogenic area, previously known as active. Until that very moment, the seismic activity level had been significantly reduced. The great number of seismic events having the epicenter in crustal depths of less than 10 km), along a brief period of time, in an area known as relatively active only to the experts in this field, as well as the impact brought upon the local communities got researchers attention, thus resulting in the subject for an integrated GNSS and seismotectonic study of the NW Galati seismogenic area.
Therefore, complex studies have taken place in the epicentral area and in the nearby regions, within a brief period of time. Those studies have been accompanied by a GPS campaign which also continued in 2014 and was followed by a third campaign in the summer of 2015. Preliminary results of the first three campaigns will be mentioned in this paper.
