There was a 4.2-magnitude in San Francisco around 2pm today. At my place it was just a sudden jerk like you would get if you were in a car going two or three miles per hour and slammed the breaks.
Just now (about 8:30pm) there was another one. It felt a big more vigorous and lasted a lot longer. Maybe 5 seconds or so. I'll have to wait a while for the news to tell me what the size was.
Well, the main reason I moved to the Bay Area was to experience an earthquake. I've experienced about 5 now, so maybe it's time to move to some place that has hurricanes.
