A reanalysis of the seismic activity at the western edge of the eastern european platform

Over the previous decades, seismic activity has sporadically increased along the western edge of the European Platform. Although the Romanian Seismic Network has been continuously enlarged, the growth in the number of events in the Romanian earthquake catalogue, ROMPLUS, in this area does not always follow the number of newly installed stations. To shed light on the patterns of seismic activity in this region, we performed a statistical analysis of events recorded between 2005 and 2021 in the ROMPLUS catalogue and used waveform correlation analysis to investigate the similarity degree and nature of these events. The poorly located events were relocated after the seismic phases were manually examined. We show that a large number of events are clustered around fault systems distributed near several quarries.
