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

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
