IRIS (Incorporated Research Institutions for Seismology) was a university research consortium dedicated to exploring the Earth's interior through the collection and distribution of seismographic data. It operated the U.S. National Science Foundation's
Seismological Facility for the Advancement of Geoscience (SAGE Facility) until 2023. IRIS programs contributed to scholarly research,

* Education and Public Outreach Program (EPO)
IRIS maintained a corporate office in Washington, D.C.
IRIS's Education and Public Outreach Program offered animations, videos, lessons, software, posters, and fact sheets to help teachers and the general public learn more about seismology and earth science and understand it better. The goal is to get more people interested in careers in geophysics.
IRIS is listed in the
Registry of Research Data Repositories re3data.org.
On January 1, 2023, IRIS merged with
UNAVCO to form the
EarthScope Consortium that now operates both the U.S. National Science Foundation's
SAGE and
GAGE Facilities through 2025.
History
In 1959, the United States Government launched a research effort aimed at improving national capabilities to detect and identify foreign nuclear explosions detonated underground and at high altitudes. The resultant
World-Wide Standardized Seismograph Network (WWSSN) was a program successful beyond its original remit. It provided seismological data for its intended purpose as well as for the emerging concept of
plate tectonics
Plate tectonics (, ) is the scientific theory that the Earth's lithosphere comprises a number of large tectonic plates, which have been slowly moving since 3–4 billion years ago. The model builds on the concept of , an idea developed durin ...

(USGS). A collaboration with the IRIS Consortium began in 1984 as a result of a need to expand and succeed the WWSSN with the Global Seismographic Network (GSN). The GSN, originally funded entirely by the USGS under the
National Earthquake Hazards Reduction Program (NEHRP), is now jointly supported by the
