The USGS labeled this one "moderate" but it's the strongest earthquake I've felt in more than 6 years of living here. House shook, everything rattled and I bolted for a door frame. Ash was sleeping - he's still on Taiwanese time. Not sure if the house shaking woke him up or if it was my screaming. I'm not a very good Californian. Every time there's an earthquake I get a big rush of adrenaline. When they're over, I'm not sure what to do other than click refresh on usgs.gov until they post the magnitude.
For those who are interested, tonight's was a 5.6, quickly followed by a 1.4, 1.5 and 1.6.
