USGS ShakeMaps provide near-real-time maps of ground motion and shaking intensity following significant earthquakes throughout the world. The maps show the epicenter of the earthquake and are color coded to show relative ground motion.
Individual maps are created for each earthquake event. Unfortunately, the maps must be accessed via their website. But I have created a sampling of several high profile earthquakes in recent years, which can be accessed from below.
To find the Google Earth KML version of an individual ShakeMap from the USGS Earthquake Hazards Program website, click on the name of the Earthquake, then click on Downloads and look under GIS Data on the right hand column for the KML link. Note, that not all of the earthquakes have a KML version.
