I'm on my lunch break, and I just popped over to Drudge Report, and they are reporting a 6.9 quake struck in in Mexico quite a bit south (330 miles!) -- but that the west end of our downtown area felt it pretty good. One office reportedly had books fall off the shelves etc.
I guess it all depends where you're standing or sitting because I'm at the east end of downtown and none of us felt squat!
The quake was centered 300 some miles south of Tijuana, and 50 miles north of Santa Isabel in Baja. No reports of damage yet, but the epicenter was in an area in the strip of sea between Baja and the Mainland. So hopefully no loss of life or anything major.
