AB: Seismological stations in Europe and its surroundings are operated, maintained and funded by more then 100 different observatories and networks. Currently more then 700 (semi)permanent broadband seismograph stations are operating within the region. This does not include semi-permanent and short-time deployments by universities and research institutes. Coordinating and implementing (real-time) data exchange is a major challenge and is done within the framework of ORFEUS (Observatories and Research Facilities for EUropean Seismology: www.orfeus-eu.org). ORFEUS is confronted both with technical challenges; data formats, large variety of instrumentation, unequal maintenance standards and communication links, and political challenges. It is therefore impressive that in a joint effort of (currently) more then 40 networks the Virtual European Broadband Seismic Network (VEBSN; www.orfeus- eu.org/meredian/vebsn.htm) was created, starting 2003. Currently close to 200 stations are contributing to the VEBSN and its numbers are steadily increasing. The VEBSN backbone, but not its only backbone, is the SeedLink data exchange protocol developed by GFZ. A de-facto standardization of this protocol in Europe enables each network to upgrade its national network with stations across its borders and consequently provide a significant improved national service. The VEBSN is currently also upgraded to operate as the core network for European scale early warnings for regional large earthquakes. The VEBSN also enables Europe to implement, operate and maintain an efficient waveform data archive. European scale funding realities have prioritized the formation of a distributed archive, the European Integrated Waveform Data Archive (EIDA). The core of which is currently being realized within the framework of the EC-project NERIES (http:neries.knmi.nl) as a joint effort of the ORFEUS data center at the KNMI in The Netherlands, GFZ in Germany, INGV in Italy and IPGP in France. The EIDA will be the European regional FDSN waveform data archive. In this presentation we will provide a description of the VEBSN, its status and current developments and a short overview of the waveform data archiving project.
