Two page publication (4MB) that features locations of the web where you can find information about specific USArray topics.
Four-page handout (3.5 MB PDF) describing how seismic tomography is used to determine Earth structure
Charles Ammon, a professor at Penn State University, has developed animations of real data showing how seismic waves sweep the transportable array of seismometers. Watch how earthquake waves originating from the US and around the world cause the ground at each seismometer to slightly shift up and down.
View how researchers use seismic waves recorded by USArray seismometers to image earth's interior.
