USArray Seismic Wave Visualizations: Educator Information
USArray), the seismologic component of EarthScope. Each animation has a map of the active USArray grid at the time of the earthquake. These animations are a creative use of the data being received by this unusually dense array of monitoring stations that were deployed as a means to "image" the roots of our continent. This notes document can help educators to give context to the animations.

These animations could be used as part of a unit on earthquakes and seismic data as an example of how geoscientists are working to better understand the structure of our Earth, particularly the North American continent. Learners should already know about P, S, and surface seismic waves.
- It is often helpful to play the animations more than once.
- If you run an animation all the way to the end, you will have a chance to show how seismic waves also travel "around the long way" as viewers watch the seismic waves sweep in from other direction.
- The animations, to which this notes document refers, were developed by the USArray portion of the EarthScope project, which is run by IRIS (Incorporated Research Institutions for Seismology). Supporting information and tutorials about the animations can be found on IRIS's Tutorial Data Visualizations page.
- The activity was presented as part of the EarthScope ANGLE Educator Workshops.
