IRIS provides management of, and access to, observed
and derived data for the global earth science community.
This includes ground motion, atmospheric, infrasonic,
hydrological, and hydroacoustic data.
Our mission is to advance awareness and understanding of seismology
and earth science while inspiring careers in geophysics.
IRIS staff and subawardees oversee the construction,
operation, and maintenance of seismic networks
and related data facilities utilized
by a wide sector of the earth science community.
IRIS consists of three directorates:
Instrumentation Services (IS),
Data Services (DS), and
Education & Public Outreach (EPO).
Each directorate consists of various programs listed to the right.
IRIS has multiple online tools that allow you
to learn about global and regional seismicity.
IRIS is a consortium of over 120 US universities dedicated
