GA‑OGS‑ARSO Transfrontier CE3RN AdriaArray Seismicity Experiment (GOAT‑CASE) installations and results (poster GNGTS 2026)

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 launched to map the Adriatic plate with a dense seismic network. OGS, GA, and ARSO provide existing data, with OGS deploying additional stations in Austria and north-east Italy, improving earthquake location regionally, including Slovenia. The GOAT-CASE experiment quantifies this improvement by relocating earthquakes and comparing results, with detection shared among partners. This poster presents the additional station deployments and compares seismic bulletins for the first two years of AdriaArray (01/07/2022–30/06/2024).
