Network of European Research Infrastructures for Earthquake Seismologywww.neries-eu.org

Infrastructure Networking• Real-time data exchange (ORFEUS/Dost)• Distributed European waveform data archive (GFZ/Hanka)• Distributed European historical data archive (INGV/Stucchi)• Access to European accelerometer data (ICC/Roca)• Broadband OBS networking (IPGP/Singh)• Portal and data services (EMSC/Bossu)• Technology Transfer (workshops, grants) (KNMI/van Eck)

Infrastructure Research• European seismological reference model (INGV/Morelli)• Real-time hazard tools (ETHZ/Wiemer)• Shake-maps and rapid loss estimation (Kandilli/Erdik)• Geotechnical site characterization (LGIT/Bard)• New approaches to data mining (UnLiverpool/Rietbrock)

Infrastructure Access (grants)• Dense broadband network seismology SDSN/ETHZ (Christofferson)• Verification seismology CEA/DASE (Guilbert)• Historical seismograms SISMOS (INGV/Ferrari)• Array seismology NORSAR (Schweitzer)• Instrumentation test facility CONRAD (ZAMG/Lenhardt)

NERIES: > 17 Activities

Seismological data to be archived and made accessible:• BB waveform data (format standard SEED)• Earthquake parameter data (format standard QuakeML)• Acceleration data (format standard to be developed)• Historical earthquake data (standard database to be developed)• Scanned historical seismograms (SISMOS)• 4-6 OBS deployments

Infrastructure components:• European data access portal consisting of portlets• European distributed waveform data archive (EIDA)

Research to provide (Software) tools:• European reference model• European shakemaps• Time varying seismic hazard maps• Site response software toolbox

Seismograph stations in EuropeShort period and Broadband

Virtual European Broadband Seismic NetworkThe 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.

Currently Operational BB stations

Exchange of waveform data in the European-Mediterranean area

Some on-going discussions: interests networks research communities

Real-time data exchangeRequired for quick locations, tsunami warning NEAMTWS, shakemaps, etc.Network sensitivities: finances and public informationMinor modification of ‘Statement of Operation’ discussed [Italy – Greece]

Near real-time data exchange(Only) efficient way for long-term data archiving for research purposesResearch priorities: unified easy accessCurrently, most networks agree, occasionally delay’s are discussed

Research communityRequests 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: Interactive Data Requests

On-going web portal developments within NERIES (NA7/NA9):

“Shopping for earthquake data in Europe and its surroundings”

Users‘clients’

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.
