Animation of Traveling Seismic Waves - January 12 Earthquake

When an earthquake happens, seismic waves instantly radiate from the epicenter.  In the United States, hundreds of seismic stations - using seismometers - measure and record those waves if they cross America.

This video animation shows seismic activity, emanating from the January 12 Haitian earthquake, as seismic waves cross the USArray's seismometer deployment.  Red circles indicate seismometer up-movement while blue circles indicate down-movement.  

To learn how the seismic recordings are made, then animated, check out the explanation at Incorporated Research Institutions for Seismology (IRIS), sponsored by the National Science Foundation.
