AdriaArray Temporary Network: Italy

INGV, UniTwente, Geo3Bcn-CSIC, GFZ temporary deployments for AdriaArray backbone network in Italy. Broadband stations deployed in Northern Italy and Sardinia to contribute to the broader AdriaArray Seimic Network. The first set of stations provided by the University of Twente was installed in the Po Plain and surrounding areas starting in December 2022. The second set, provided by Geophysical Instrument Pool Potsdam (GIPP), was deployed in Sardinia beginning in September 2023. The collected data is available through the INGV EIDA (European Integrated Data Archive) node and has been fully open from the beginning of stations operations, according to the general open data policy of INGV (https://data.ingv.it/docs/principles/), in line with international recommendations (e.g. EPOS‑European Plate Observing System, Freda et al., 2018).

AdriaArray (https://orfeus.readthedocs.io/en/latest/adria_array_main.html) is a multi-national initiative to cover the Adriatic Plate and its active margins in the central Mediterranean by a dense regional array of seismic stations to understand the causes of active tectonics and volcanic fields in the region. Plate-scale observations are complemented by local and LargeN experiments in key areas. The AdriaArray region reaches from the Massive Central in the west to the Carpathians in the east, from the Alps in the north to the Calabrian Arc and mainland Greece in the south. The deployment of seismic stations and scientific research is coordinated by the AdriaArray Seismology Group based on FAIR and open data exchange. Analyses of seismicity and multi-scale passive seismic imaging will lay the ground for a physical understanding and modelling of plate deformation and associated geohazards.

At the core of the AdriaArray initiative is the acquisition of broadband seismic data from a dense network of stations. This includes temporary deployments to improve the coverage and geometry of existing permanent broadband networks operated by various seismic services across Europe. About 440 temporary stations from 23 mobile pools from 14 European countries were made available and deployed as part of the AdriaArray Seismic Network (Kolínský et al., 2025).
