Abstract The Incorporated Research Institutions for Seismology's (IRIS) Education and Public Outreach (EPO) program is committed to advancing awareness and understanding of seismology and geophysics while also inspiring careers in the earth sciences. To achieve this mission, the IRIS EPO program combines the content expertise of the consortium membership with the educational and outreach expertise of IRIS staff members to create programs, products, and services that target a range of audiences, including students and teachers in grades six through 12, undergraduate and graduate students, faculty, researchers, and the general public. Since 1998, the IRIS EPO program has produced a portfolio of freely available products and services and offers a rich repository for anyone who teaches seismology-related topics and/or communicates seismology research to the general public.
