Seismograph stations in Europe Short period and Broadband

Virtual European Broadband Seismic Network The VEBSN concept The VEBSN: consists of a pool of broadband seismograph stations, the data of which is shared in (near) real-time by European seismological observatories. data is shared on the basis of the VEBSN statement of operation. is the efficient vehicle to gather and archive data for scientific research. data backup is secured in the European Integrated Data Archive, pragmatically the European regional FDSN archive.

Exchange of waveform data in the European-Mediterranean area Some on-going discussions: interests networks  research communities Real-time data exchange Required for quick locations, tsunami warning NEAMTWS, shakemaps, etc. Network sensitivities: finances and public information Minor modification of ‘Statement of Operation’ discussed [Italy – Greece] Near real-time data exchange (Only) efficient way for long-term data archiving for research purposes Research priorities: unified easy access Currently, most networks agree, occasionally delay’s are discussed Research community Requests all data and all in real-time. Notably IRIS policy! Can contribute with ‘added value’ tools for improvement of network performance. (rapid magnitude, Moment tensors, shakemaps, location, …) Network interests + research results  improved network performance.

NERIES: Promotes networking of earthquake data providers and users. Pursues active cooperation with related projects Provides facility access grants for EU scientists/groups. Workshops and meetings are open. Developed software in public domain (GNU license) ORFEUS complements with limited small scale support. NERIES: Opportunities beyond the consortium NERIES: The first infrastructure step towards an European Plate Observatory System. NERIES e-science developments in collaboration with similar developments in the US (EarthScope). NERIES builds on a long-standing global data exchange agreements and formats in seismological earthquake data.
