Central seismological observatory
The Central Seismological Observatory ( SZGRF ) in Hanover is a department of the Federal Institute for Geosciences and Natural Resources . Furthermore, the SZGRF forms a research facility of the Research College Physics of the Earth (FKPE) and is a partner institute of the University of Erlangen-Nuremberg . In addition to the operation of the seismic network Graefenberg-Array (GRF) in the area of the Franconian Alb and the German regional network (GRSN, German Regional Seismic Network), the seismological central observatory is the national seismological data center.
Tasks and main areas of work
- Operation and monitoring of the GRF and GRSN
- Operation and expansion of the infrastructure for the national seismological data archive
- Routine evaluation of seismic events in Germany and worldwide
- Processing of scientific orders from the German Research Foundation
German Regional Seismic Network
A network of broadband seismological stations has been set up in Germany since 1991. On the one hand, they serve to monitor local seismicity and , on the other hand, they improve the evaluation options for regional and teleseismic earthquakes . The data is recorded continuously. All recordings are available to everyone on the SZGRF website.
As of October 2005, the following stations are active (international station ID in brackets):
- Helgoland (HLG)
- Rügen (RGN)
- Bad Segeberg (BSEG)
- Ibbenbüren (IBBN)
- Rüdersdorf (RUE)
- Bochum (BUG)
- Lower Saxony Riedel (NRDL)
- Clausthal-Zellerfeld (CLZ)
- Collm (CLM)
- Neuburg (NEUB)
- Berggießhübel (BRG)
- Unterbreizbach (UBBA)
- Moxa (MOX)
- Werda (WERD)
- Gunzen (GUNZ)
- Tannenbergsthal (TANN)
- Taunus (TNS)
- Nottersdorf (NOTT)
- Graefenberg (GRFO)
- Wettzell (WET)
- Stuttgart (STU)
- Station of the GERESS array (GEC2)
- Black Forest Observatory Schiltach (BFO)
- Fürstenfeldbruck (FUR)
All stations are installed in special bunkers or suitable basements in order to minimize external disturbances.
