FDSN Network Information

FDSN code G Network name French Global Network of Seismological Broadband Stations (GEOSCOPE)
Start year 1982 Operated by
End year - Deployment region

The GEOSCOPE network (G) is a global seismological network created in 1982 to respond to the challenge of instrumenting isolated sites all around the world.
The GEOSCOPE network is primarily dedicated to research and its data are used for studies of Earth structure and dynamics, seismic sources, time dependent seismology and environmental seismology.
All stations are equipped to provide real-time data, used for rapid source determination (among others by tsunami alert centers).
Most of the stations include a very broad band seismometer (STS1), and the remaining ones a broadband seismometer (STS2 or Trillium 240).
Stations are usually installed in vaults with special equipments aimed at reducing long period noise related to atmospheric pressure variation.
Data of this network are freely and fully disseminated in SEED format (both in real time and after validation) by the IPGP, RESIF and IRIS data centers.
