This video was produced by IRIS, a consortium of universities supported by the National Science Foundation. It represents data compiled from an array of seismic detectors called USArray.
Watch as the seismic waves from the Aug. 23 earthquake sweep across the country, which then jiggles like a bowl of Jell-O. The red color indicates upward motion, blue indicates downward motion. The intensity of the color indicates the amount of movement.
Did you feel the earthquake? What were you doing?
