I experienced my first earthquake on Monday morning while at work in Pleasanton.  I suddenly felt very dizzy sitting at my desk staring at the computer screen, and then people started talking about a shaker.  It was centered just south of San Jose.  Below is the official read-out from whatever agency tracks these things.  Not sure though what “Quality” of an earthquake means…”good”?   ——- I  🙂
