IRIS 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.
IRIS 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 IRIS 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.
IRIS is a consortium of over 125 US universities dedicated to the operation of science facilities for the acquisition, management, and distribution of seismological data, and for fostering cooperation among IRIS members, affiliates, and other organizations in order to advance seismological research and education.
Novice - Basic seismology topics. Activities emphasize skills and abilities generally associated with students in the middle and high school grades.
Intermediate - Basic and/or intermediate seismology topics presented through activates that emphasize skills and abilities generally associated with high school and non-majors undergraduate courses.
Advanced - Intermediate and/or advanced seismology topics presented through activates that emphasize skills and abilities generally associated with undergraduate science majors.
Expert - Advanced and/or expert seismology topics presented through activates that emphasize skills and abilities generally associated with graduate students and faculty.

IRIS offers a range of resources for students, educators and the general public.
Activities - Bite-sized (5, 15, or 30 minute) demonstrations or student tasks tied to ‘Did You Know?’ questions to engage the learner.
Animations - Concise animations that illustrate fundamental concepts that are difficult to convey to learners through other means (the real events may be too small, too large, too fast, too slow, or unsafe for the classroom).
Course - A series of lessons that provide the structure for a semester-long undergraduate course.
Demos - Quick teacher-lead activities (show-and-tell combined with an opportunity for learners to ponder, predict and discuss) to stimulate interest and convey a concept to learners.
Fact-Sheets - Single page, accessible, discussions of earthquake related topics.
Interactives - Uses interactive Flash (sfw) to illustrate fundamental concepts that are difficult to convey to learners through other means.
Lessons - A step-by-step guide outlining what students will learn across one or more class periods, through a progression of activities, combined in a learning cycle, to achieve the desired student learning.
Posters - More than just wallpaper, these eye-catching, educative posters invite students to become minds-on with Earth's internal structure, earthquakes, seismic waves and more!
Software-Web-Apps - Stand alone software, interactive web tools, and downloadable apps to help you explore seismic data and earthquake topics.
Videos - Concise video lectures give background information on the Earth and plate tectonics for teaching how earthquakes happen and how they are studied.
