The Seismic Network is operated by the Institute of Geodynamics. The service to monitor seismicity in Greece and the adjacent region has started back in 1893 with the first seismic network operating five stations. In 2000, a large upgrade towards digital monitoring with broadband stations was initiated.

Today, the Hellenic Unified Seismic Network (HUSN), with Institute of Geodynamics as coordinator and the three University Seismic Networks (Athens, Thessaloniki and Patras) as partners, provides seismological data in near real time from more than 150 stations.
