IRIS Mission

  • Facilitate and conduct geophysical investigation of seismic sources and Earth properties using seismic and other geophysical methods.
  • Promote exchange of geophysical data and knowledge, both through use of standards for network operations, data formats and exchange protocols, and through pursuing policies of free and unrestricted data access.
  • Foster cooperation among IRIS Members, Affiliates, and other organizations in order to advance geophysical research and convey benefits from geophysical progress to all of humanity.

IRIS - Consortium and Facilities(with possible connections to CIDER)
  • Let science lead
    • Close links between science and facilities
    • No in-house research
      • CIDER as intellectual driver
  • Engage and renew community involvement
    • Respond to community leadership and advice
    • Renew through E&O
      • Links to CIDER education and training
  • Build facilities that facilitate
    • Carefully spec’ed, designed and tested instrumentation
    • Data management that works for research community

“24 bits wide - 70 terabytes deep”

      • Links to COMPRES and other geophysical and geological databases
    • Emphasis on quality and service
    • Extension into services and products
      • Links to CIDER, CIG
  • Develop multi-use, multi-agency, multi-national support
      • Links to CIDER interdisciplinary science
nsf support for seismology and deep earth evidence for optimism invitation for response
NSF Support for Seismology and Deep EarthEvidence for OptimismInvitation for Response
  • IRIS and GSN
    • 25 years of sustained support for development and operation
  • Recent 2009 ARRA - Stimulus actions
    • NSF and USGS combined support of $10M for GSN revitalization
    • EarthScope O&M support through 10/10
    • Cascade Initiative - “on-shore - off-shore”

long range science plan for seismology
Long Range Science Plan for Seismology


From the 2006-2011 IRIS-NSF Cooperative Agreement:

“The IRIS Consortium will consult broadly with the research community to develop a new long-range science plan for global seismology that will guide potential future improvements and enhancements to the IRIS facilities.”

Ten Grand Challenges for Seismology

  • How do faults slip?
  • How does the near-surface environment affect natural hazards and resources?
  • What is the relationship between stress and strain in the lithosphere?
  • How do processes in the ocean and atmosphere interact with the solid Earth?
  • Where are water and hydrocarbons hidden beneath the surface?
  • How do magmas ascend and erupt?
  • What is the lithosphere-asthenosphere boundary?
  • How do plate boundary systems evolve?
  • How do temperature and composition variations control mantle and core convection?
  • How are Earth’s internal boundaries affected by dynamics?

Sustaining a Healthy Future for Seismology

  • Building and sustaining the professional pipeline
  • Enhancing access to high-performance computing capabilities
  • Sustaining global observatories
  • Advancing portable instrumentation
  • Providing controlled seismic source support
  • Producing advanced seismological data products
  • Enhancing free and open access to data
  • Enhancing interdisciplinary coordination
