EarthScope Consortium is a 501(c)(3) nonprofit geophysical science support organization. EarthScope Consortium operates two of the National Science Foundation's (NSF) major research facilities, the NSF Geodetic Facility for the Advancement of Geoscience (NSF GAGE) and the NSF Seismological Facility for the Advancement of Geoscience (NSF SAGE), which provide geophysical instrumentation, data access, and services to support geoscience research and education.

EarthScope Consortium's corporate headquarters are located in Washington, D.C., and an instrument facility is located in Socorro, New Mexico.

EarthScope Consortium was formed on January 1, 2023 through the merger of the Incorporated Research Institutions for Seismology (IRIS) and UNAVCO. Both founded in 1984, IRIS and UNAVCO supported the U.S. scientific community's access to data, instrumentation, and educational resources within seismology and geodesy, respectively.

The "EarthScope Consortium" name is connected to IRIS and UNAVCO's previous collaboration in the 2003–2018 NSF-funded EarthScope Program, which included operation of the USArray and Plate Boundary Observatory components.

The EarthScope Primary Instrument Center (EPIC) (formerly known as the IRIS PASSCAL Instrument Center) is located in Socorro, New Mexico at the New Mexico Institute of Mining and Technology and houses central instrumentation maintenance and engineering activities.

EPIC supports geophysical network operations in global and regional scientific networks, including:

EarthScope Consortium is the operator of the NSF's Geodetic Facility for the Advancement of Geoscience (GAGE), previously operated by UNAVCO since the facility's creation in 2013. The NSF GAGE Facility funding is designated to support:
