Anza. I think it's dapperdan that bought some property out there.
I felt it big time. Stood up and made ready to head for the door; then it stopped. Been in SoCal my entire life, so I don't get spooked by 'em, but I do take precautions.
Funny thing, even though I felt and heard it, others in north San Diego county where I live didn't feel a thing.
