Would be intresting to see a more detailed map showing the depth of the earthquakes in the USA to compare with the frequency to see if there any precursors to a large quake. Do you know if a map like this is available in USGS as well? Is 800 odd quakes normal in a week?

missing out on any substantial shaking
Starting in January 2009, the USGS National Earthquake Information Center no longer locates earthquakes smaller than magnitude 4.5 outside the United States, unless we receive specific information that the earthquake was felt or caused damage.
