Looks like a 6.4 just hit off the Norcal coast, aftershock? There does seem to be a connection of some kind, The incidence of 5+ quakes from the 7.9 in Chile on up through California quakes this last week, sure makes a strong pattern on the maps. Any thoughts on "chain reaction" type of quakes??

By the way, this quake is not yet on the Ca.-Nev map........!
