All seismic recording stations in the continental US recorded increased seismic activity at approximately the same time today.....twice.  One just happened within the last hour or so.

This has been going on for a few days but today's was the strongest I've seen and haven't seen it repeat before.  Keep an eye on this site:  http://aslwww.cr.usgs.gov/Seismic_Data/heli2_us.shtml

Note that the earth movement was from the western states to the eastern states within about a 30 minute period.
