GA-OGS-ARSO Transfrontier CE3RN AdriaArray Seismicity Experiment (GOAT-CASE) installations and results (7th AdriaArray Workshop 2026 poster)

The Italian National Institute of Oceanography and Applied Geophysics (OGS), GeoSphere Austria (GA), and the Slovenian Environment Agency (ARSO) monitor seismicity in north-east Italy, Austria, and Slovenia, collaborating with civil protection authorities. In 2014, they founded the Central and Eastern Europe Earthquake Research Network (CE3RN) to coordinate cross-border monitoring, enhance research, and support civil protection. In 2022, the AdriaArray experiment was initiated to image the Adriatic plate with a dense seismic network. Within this framework, OGS, GA, and ARSO contribute their permanent seismic stations data, while OGS additionally deploys temporary stations across Austria and north-eastern Italy, enhancing regional earthquake location capability, including for neighbouring Slovenia. The GOAT-CASE experiment quantifies this improvement by relocating earthquakes and comparing the corresponding solutions, with phase detection shared among the participating institutions. This poster presents the additional station deployments and compares seismic bulletins for the first two years of AdriaArray (01/07/2022–30/06/2024).
