AdriaArray – a Passive Seismic Experiment to Study the Geodynamics and Geohazards in Central Mediterranean

Description: 

The densely populated area around the Adriatic Sea is prone to geohazards including earthquakes, tsunamis, landslides, flooding and volcanic activity as the Adriatic Plate is consumed in a tectonically active belt spanning from Sicily, over the Apennines to the Alps, Dinarides and Hellenides, generating earthquakes up to magnitude 7. To identify drivers of associated plate deformation, the plate boundaries, slabs, properties of active faults and of the stress field have to be determined. AdriaArray, a dense plate-scale regional seismic network deployed in the central Mediterranean, provides data for imaging of the crustal and upper mantle structure and for the analysis of seismic activity. The network consists of 1000 permanent and 446 temporary BB stations from 24 mobile pools. 95 % of the planned temporary stations have already been installed. A homogeneous coverage by broadband stations in an area from the Massif Central in the west to the Carpathians in the east, from the Alps in the north to Sicily and the Kefalonia Fault Zone in the south, is achieved. The backbone network (2022 – 2025) is complemented by locally densified and LargeN networks, e.g. in the western Carpathians (Poland, Slovakia, Hungary), along the Dubrovnik fault (Croatia), in the Vrancea region (Romania), and in Albania. Data recorded by the temporary stations is transmitted in real-time and archived at 9 nodes of the European Integrated Data Archive (EIDA). Regular availability and quality checks ensure high data usability. AdriaArray, the largest passive seismic experiment in Europe so far, is based on cooperation between local network operators, mobile pool providers, field teams, ORFEUS (Observatories and Research Facilities for European Seismology) and EPOS (European Plate Observing System), encompassing 63 institutions from 30 countries. They form the AdriaArray Seismology Group, founded in 2022. Collaborative Research Groups are being established to coordinate the data analysis. We present the maps of the AdriaArray Seismic Network, station properties, coverage, contributing institutions and collaborative research topics.
