AdriaArray (AdA) is an ambitious initiative that brings together numerous institutions from across Europe, to investigate the processes responsible for Adriatic Plate deformation and the kinematics of active fault systems in surrounding areas.

Romania’s participation in AdA is significant due to its unique tectonic and geophysical characteristics. The country is located at the intersection of major tectonic structures, including the Vrancea seismic zone (VSZ) at the bend of the Eastern Carpathians.  The VSZ is one of Europe’s most active regions for intermediate-depth earthquakes, that can generate two to four large-magnitude events (M > 7) per century, with widespread impacts, making Romania a critical area for seismic hazard research. The deployment of 44 mobile broadband seismic stations across Romania as part of the AdA project has greatly enhanced the ability to monitor and analyze seismic activity. This includes both subcrustal earthquakes in the VSZ and crustal seismicity developed mostly along the Carpathian Orogen.

This large amount of data recorded by mobile AdA stations alongside the permanent stations of the Romanian Seismic Network will enhance our understanding of Romania’s lithospheric structure, mantle dynamics, and regional stress fields. These insights are crucial for refining seismic hazard models and improving the assessment of potential impacts from large intermediate-depth earthquakes, ultimately helping to mitigate their effects on densely populated areas.

This study highlights Romania’s role in AdA initiative, focusing on the comprehensive seismic station coverage achieved, the monitoring and data availability from mobile stations, and the data quality control. These efforts represent a solid foundation for carrying out advanced seismic analyses and offering new interpretations of the tectonic processes and mechanisms of earthquake generation in this highly active region.
