Seismic Data available from the IRIS (Incorporated Research Institutions for Seismology) Consortium

These nodes work together to insure the smooth flow of GSN data from the stations to the seismological research community. The IRIS Global Seismographic Network (GSN) is one of the four major components of the IRIS Consortium. The goal of the GSN is to deploy 128 permanent seismic recording stations uniformly over the earth's surface.

The GSN provides funding to two network operators: - IRIS/ASL Network Operations Center Albuquerque, New Mexico, operated by the United States Geological Survey; and - IRIS/IDA Network Operations Center La Jolla, California, operated by personnel from Scripps Institution of Oceanography. PASSCAL is one of two major instrumentation programs of IRIS (the other being the Global Seismic Network or GSN). PASSCAL operates a pool of over 400 portable seismic instruments to record active source reflection data, active source refraction data or natural source recordings of earthquakes (see Instrumentation for more details).

The instrumentation is currently housed and supported by an instrument center at New Mexico Tech, Socorro, New Mexico. PASSCAL Instruments and support are available to the academic research community according to the rules and policies set by the IRIS Executive Committee. All data from PASSCAL supported experiments are made available through the IRIS DMC in Seattle, Washington.

The IRIS Education & Outreach (E&O) program, in collaboration with the seismological and educational communities, develops and implements IRIS programs designed to enhance seismology and Earth Science education in K-12 schools, colleges and universities, and in adult education. Our goal is to foster within the next generation of research scholars, educators, policy-makers, business leaders and benefactors an appreciation for and an understanding of seismology and related study of the Earth.
