California earthquake shakemap. Maps are updated within 1-5 minutes of an earthquake or once an hour. These maps are based on shaking parameters from stations in the combined seismographic networks, supplemented with predicted ground motions in areas where limited data are available, and are distributed electronically within minutes of the occurrence of the earthquake. ) ShakeMap Home Page Choose "Most Recent Event" to see maps for the most recent earthquake, select one of the maps from the list of "Recent Significant Events" or click on the "Map Archive" tab at the top of the page to view past events.
