Federation of Digital Seismic Networks

1
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 Earths 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

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

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

FDSN Focus 2002-2006

• 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

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, DMC, ORFEUS
• With CTBT and GEOSS the political role of the
  FDSN increased
• Opening to new types of data and networks

10
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

11
How to increase the FDSN impact

• Provide effective representation of the whole
  earthquake monitoring community
• Integration of national efforts and global
  coordination
• Effective presence in the ICG/IOTWS, GEO
  assemblies and management, GEOSS WGs
• Lobbying for global and regional seismology
• EO
• A stronger interaction with ION and CTBTO
