GEO, Washington, Domenico Giardini FDSN Federation of broad-band Digital Seismic Networks Domenico Giardini FDSN Chairman GEOSS Workshop Washington, August 23-24, 2005

GEO, Washington, Domenico Giardini FDSN Federation of Digital Seismic Networks The FDSN is the organization that brings together the digital broad-band seismographic networks throughout the world has commission status within IASPEI, the International Association of Seismology and Physics of the Earth’s Interior, and IUGG, the International Union of Geodesy and Geophysics (ICSU) was founded in 1985 to support the establishment of new digital broad- band seismographic technology, primarily for scientific network. As many national networks moved and are moving to digital technology, FDSN has assumed the coordination role among all modern seismographic networks worldwide is not an inter-governmental organization

GEO, Washington, Domenico Giardini FDSN Federation of Digital Seismic Networks The FDSN promotes the installation of modern digital broad-band stations: over 2000 BB digital stations globally today, over 1000 openly available in real-time telemetry coordinates global activities in station site selection, data exchange, and instrumentation standardization promotes inter-operability among infrastructures promotes a variable-geometry approach, with a backbone of over 200 globally distributed, high-quality stations, enhanced by a mosaic of national and regional networks promotes the deployment of ocean-bottom seismic observatories, in cooperation with other international ocean programs (ION), to complement the coverage of land-based seismic instrumentation

GEO, Washington, Domenico Giardini FDSN Federation of Digital Seismic Networks The FDSN maintains an advanced system of networked data centers to oversee the collection, archive and distribution of the continuous and event waveforms, with primary FDSN archive at IRIS Data Management Center in Seattle promotes open-data access: all FDSN member networks agree to open-data availability; each member contributes at least one station to the global archive and most members allow open access to waveform data at their data centers provides global monitoring of one of the most important natural hazards - earthquakes - and shares the GEOSS goal of achieving a global strategy for coordinated Earth observation; FDSN is a GEOSS participant, building the land-based component for one of the priority targets for the GEOSS 10-yr implementation plan

GEO, Washington, Domenico Giardini FDSN FDSN Focus Improve data availability and real-time data availability Complete global distribution Increase regional participation 2004 Europe, Potsdam 2005 Latin America, Santiago 2006 SE Asia Maintain data quality standards Expand to other types of data: portable deployment, SM Promote multi-parameter observatories and OBS GEOSS

GEO, Washington, Domenico Giardini FDSN Open Issues Regional versus global What is the FDSN today ? GSN/FDSN FDSN or gFDSN or IFSN or... What can the FDSN contribute to GEOSS How to increase the FDSN impact

GEO, Washington, Domenico Giardini FDSN FDSN Global Backbone

GEO, Washington, Domenico Giardini FDSN FDSN Global Backbone

GEO, Washington, Domenico Giardini FDSN Euro-Mediterranean seismic stations 46 countries 150 infrastructures 800 BB stations 1800 SP stations 3000 SM stations

GEO, Washington, Domenico Giardini FDSN What is the FDSN today ? Increasing role of national networks in global monitoring and in the FDSN. These generally are supported for surveillance and alert have more stable budget, recognition and support are less interested in technical developments require real-time data availability and processing are less strict about VBB standards participate less in FDSN activities The FDSN evolved from a small group of science-driven projects to a worldwide coverage of national agencies, although the major players remained the same Crucial role of IRIS GSN and DMC With CTBT and GEOSS the political role of the FDSN increased Opening to new types of data and networks

GEO, Washington, Domenico Giardini FDSN What can the FDSN contribute to GEOSS Provide global backbone (200 stations) and regional high-density (1000 stations) free real-time coverage around the world, to allow earthquake and tsunami early warning and alert Promote and assist in deploying high-quality instrumentation and ensuring technology transfer Facilitate the inter-operability of national and regional infrastructures Provide integration in the global seismological infrastructure community Promote access to the global research seismological community Encourage open archival data exchange, and provide back-up capability and data distribution facilities for national data centers Facilitate the exchange and access to ocean bottom observing systems GEOSS Targets 003 and 091

GEO, Washington, Domenico Giardini FDSN How to increase the FDSN impact Active participation in various meetings and fora (in the last 12 months Potsdam, Ottawa, Bruxelles (2), Paris (2), Geneva (x), Thailand, Iran, Tajikistan, Washington, Chile) Effective presence in the ICG/IOTWS, GEO assemblies and management, GEOSS WGs Regular information to members and outside the FDSN (web, bulletin) Lobbying for global and regional seismology Presence at major scientific assemblies E&O program ? A stronger interaction with ION and CTBTO Status ? Governmental recognition ? Budget ? Annual quotas ?
