All shook up

Kids are in bed; Chris is in class; I was sitting at the computer in a quiet room when the house started shaking and I could feel a loud rumble. I jumped up while searching for clues as to what was going on and the shaking stopped. Apparently we've just had an earthquake. No apparent damage. Kids didn't even wake up. My hands sure feel a little shaky though. Media isn't as fast here so I guess we'll know by later this evening or tomorrow how strong the quake was. Back to work now...

UPDATE:
Just found out. It was only 3.3 on a Richter scale (4-5 on Mercalli scale). However, it turns out that we were about a mile from the epicenter so I suppose it felt strong. Back to work now... (again).
