Earthquake Ground Motion Annimation 08-15-2007 Central Peru

Central Peru - 15 August 2007, 23:40:48 UTC (Mw = 8.0)

The animation shows the vertical ground velocity in the 100-50s period range observed across the western United States by the EarthScope transportable array and generated by the great 15 August, 2007 earthquake offshore centrl Peru. Each circle represents a seismometer and the colors change to reflect variations in the signal amplitude crossing the array. Near the end of this animation you can see the waves that traveled the long way around Earth to reach the western United States (they propagate from NW to SE).
