Seismological Facility for the Advancement of Geoscience

The Seismological Facility for the Advancement of Geoscience (SAGE) is a distributed, multi-user national facility that provides state of-the-art seismic research. It is operated by the EarthScope Consortium. Its previous operator was the Incorporated Research Institutions for Seismology (IRIS), until its merger with UNAVCO to become the EarthScope Consortium. SAGE is one of the two premier geophysical facilities in support of geoscience and geoscience education of the National Science Foundation (NSF). The other premiere geophysical facility is GAGE, the Geodetic Facility for the Advancement of Geoscience.

The services of the facility include the Global Seismolographic Network (GSN), Data Services, the Earthscope Primary Instrument Center (EPIC), and EPIC MT for research in application of magnetotelluric (MT) or electromagnetic geophysical research to seismology research.

Global Seismographic Network (GSN)
SAGE manages a 152-station Global Seismographic Network (GSN) for the basic global seismicity and Earth structure research.

It also carries out earthquake hazard mission-related data operations such as:


 * Earthquake location and characterization
 * Tsunami warning
 * Nuclear explosion monitoring

Data Services
SAGE Data Services (DS) is the largest facility for the archiving, curation, and distribution of seismological and other geophysical data in the world.

EarthScope Primary Instrument Center (EPIC)
SAGE EPIC facility maintains the largest open access, shared-use pool of portable seismic sensors in the world. It is located on the campus of New Mexico Tech.

EPIC MT
Epic MT carries out magnetotelluric (MT) or electromagnetic geophysical research for the recording of our planet's ambient electric and magnetic fields, which allow for the characterization of the conductivity of the area consisting of the shallow crust to upper mantle. This helps with analysis of results obtained from seismic imaging methodologies.

The SAGE EPIC MT facility is:


 * Developing open source MT data formatting and processing software.
 * Providing access to proprietary software products.
