This Google Earth map overlay shows the earthquake intensity data from the USGS Shake Map but has been displayed on a much higher resolution terrain map (see this post for more information on the terrain base map). The red shaded areas are where the earthquake was the strongest. A more technical explanation can be found at the USGS website. Also included is an option to overlay the contours of the Peak Ground Acceleration (% g) values.
