Moderate magnitude 5.6 earthquake in San Francisco Bay Area

Just experienced a moderate intensity earthquake here - I was watching the end of the democratic presidential debate - nothing earth shaking there - so I was kinda surprised when the earth literally started shaking :-)

I think this was the biggest shaker that I've felt here in the Bay area - during my 8 years here. But really, out here in Fremont, it was mostly exciting than frightening. I guess small shakers like this might actually do some good - in that they remind us to be prepared for the big one. I guess emergency kits will be flying off the shelves at various Bay Area stores in the coming days.
