Seismic Wavefield Animations

Link to Animations

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.
