GEOFON and Its Role in Indian Ocean Tsunami Warning Joachim Saul, Toni Kraft and Winfried Hanka GITEWS

● is primarily focused on networking and capacity building ● is known for simple, but efficient and innovative technical solutions ● acts as a support center and integration and coordination point for many networks and data centers ● operates its own permanent cooperative network (global with densification in Europe and recently in the Indian Ocean area) ● acquires real-time and other data from many partner networks and other public data sources ● operates automatic rapid global and regional earthquake information services ● plays a major role in the setup of the Indian Ocean Tsunami Warning System (IOTWS) and for a possible future EuroMed TWS (NEAMTWS) ● deploys temporary networks ● operates the largest data archive in Europe as primary or secondary archive for many partner networks and several mobile instrument pools ● is the largest node in ORFEUS's future European Integrated Data Center (EIDAC) structure GEOFON

It is ● the largest seismological data archive in Europe (~ 9 TB) ● the primary archive and dissemination point for the ● permanent GEOFON VBB network (56 stations) ● passive seismological experiments of the GFZ Geophysical Instrument Pool (GIPP) and other pools in Germany and Europe (> 50 experiments) ● the secondary (backup) archive and dissemination point for the GEOFON partner networks In Europe, SE Asia and in future maybe Central America and Africa It ● imports NRT data from > 30 networks over Internet (GEVN) ● exports NRT data from 25 partner networks over Internet (through its public SeedLink server) ● has online data holdings of ~18 TB (mirrored), backups volumes and raw data in tape archive The GFZ Seismological Data Archive
