SAGE provides management of, and access to, observed and derived data for the global earth science community.
This includes ground motion, atmospheric, infrasonic, magnetotelluric, strain, hydrological, and hydroacoustic data.
SAGE facilitates seismological and geophysical research by operating and maintaining open geophysical networks and providing portable instrumentation for user-driven experiments.
Instrumentation support includes engineering services, training, logistics, and best practices in equipment usage.
All data collected with SAGE instrumentation are made freely and openly available.
Our mission is to advance awareness and understanding of seismology and earth science while inspiring careers in geophysics.
Established in 2018, NSF’s Seismological Facility for the Advancement of Geoscience (SAGE) is a distributed, multi-user national facility operated by EarthScope that provides state of-the-art seismic and related geophysical instrumentation and services to support research and education in the geosciences.
