Description:
2023 marks thirty years since the start of GEOFON operations with the first three stations in Papua New Guinea (Port Moresby, PMG), the Czech Republic (Moravsky Beroun, MORC), in Ireland (Dublin, DSB). The GEOFON program started shortly after creation of the GFZ German Research Centre for the Geosciences in 1992 with the aim to promote global seismic monitoring, standardisation and data exchange. The program has evolved over the three decades in synergy with the seismological community through three important milestones: since late 1990s the development and community adoption of the SeedLink protocol enabling global real-time data exchange; in early 2000s, development of the Arclink protocol as key development to interconnect the EIDA federated data archives, only recently superseded by the use of FDSN web services at global scale; 2008 as the first public release of SeisComP, one of the most widely used seismological packages in seismology, a development triggered after the 2004 Aceh-Andaman earthquake and tsunami within the GITEWS project (German Indian Ocean Tsunami Early Warning System). Although GEOFON‘s heritage goes back to the 1990s and further down to 1889 building on the initial findings from Ernst von Rebeur-Paschwitz, the program is capable of leveraging third party funded challenging projects to keep modernising with the community. In this presentation we outline the most important developments of GEOFON through a journey in time over three decades, building links between current activities and vision still influenced by the initial aims which have shaped the current GEOFON mission.
