The GEOFON archive includes over 170 seismic networks with more than 5700 stations, spanning 28 years from 1993 to today. Most data is open and available on request.
The GFZ Seismological Data Archive is the largest seismological data archive in Europe. It holds data from the permanent GEOFON VBB seismic network. For many GEOFON partner networks, GEOFON acts as backup archive and data distribution center. Additionally, data from many temporary station deployments are permanently archived at GEOFON, in particular passive seismological experiments of the GFZ Geophysical Instrument Pool Potsdam (GIPP) and the German Task Force Earthquake (data archival pending).
Real-time data streams from permanent networks are mostly acquired over the Internet and are immediately accessible as continuous data stream by SeedLink real-time feeds or on request from the archive. Most of the European networks acquired are contributed to EIDA. (In part EIDA grew out of an earlier concept, the VEBSN.) Although the archive consists mostly of data from broadband stations, a substantial amount of short period data is archived as well as some strong motion and OBS data.
The GEOFON Data Archive is linked to other partner data centers in Germany (German Integrated Data Archive - GIDA) and Europe (European Integrated Data Archive - EIDA). This integrated data archive infrastructure allows transparent access to the data of all participating archives through a single front-end data portal. All data are accessible in a unified way through FDSN web services and SeedLink.

Several methods are available to access waveform data from the GEOFON archive:
Access is restricted for:
Please note we monitor requests of these data. Your personal data, generally credentials used to identify you to us, such as an e-mail address, are collected and retained. These are used to check whether you are allowed access to the data you request. Summary statistics for restricted networks are shared with the relevant data providers, for example project principal investigators (PIs) for temporary deployments, to enable them to understand usage of their data, and verify that their data sets are being shared according to their requirements. Some of these data providers are external to GFZ.
GEOFON/GEVN data are available as real-time data feeds without special permission by the SeedLink protocol from the GEOFON SeedLink server at geofon.gfz-potsdam.de:18000. A visualization of the GEOFON real-time stations is provided in the form of "live" seismogram plots.
