Conveniently, I found this website that lists all the earthquakes in the last 7 days. And that confirmed it -- indeed I just experienced my first quake:
|2.6||2007/11/17 02:55:19||34.376||-119.651||0.0||SANTA BARBARA CHANNEL, CALIFORNIA|
|3.4||2007/11/17 02:45:08||34.390||-119.658||10.3||SANTA BARBARA CHANNEL, CALIFORNIA|
I have to say, it was sort of exciting. A 3.4 quake followed by a 2.6 one, and I could feel them and nothing bad happened. I think anything over a 5 would scare me out of my wits, but for now, that was cool.
