A bit farther south, if you compare the archive of Hurricane Henrietta‘s locations with the earthquake epicenter reports, you see that the southern tip of Baja received a 5.0 jolt just as it was being raked by hurricane winds.
Meanwhile, recent hurricane convergences are record-setters. Today is only the second time on record2 that the Americas are receiving a hurricane on both the Atlantic and Pacific coasts in the same 24-hour period. The one on the other side, is, of course, far bigger. Felix is now a tropical depression, dumping rain on Central America, but came ashore as a Category 5. This is the first time two Category 5 storms have hit the Caribbean region in the same season, following Dean just over two weeks ago. Felix has already broken an “unofficial record” as the “most explosive” hurricane ever in the Atlantic basin, surpassing Wilma, in October, 2005.
Update: That first link will always show the most recent earthquakes in the area, so those referred to above will fall off the page after a bit. However, a check today–9 Sept.–shows yet another 4.0 off the northern San Diego County coast last night. (There was also a 3.7 off La Jolla this morning). This last couple of weeks has represented the greatest flurry of (small) earthquake activity I can remember in the area in quite some time.
