OT - Earthquake!

I'm near Philly, and did not feel it at all. I have no idea what I was doing when it hit but I only heard about it on the car radio later on. I'm originally from CA and I remember vividly some earthquakes while growing up.

 Yup, felt it here in the DC metro.  i've had a migraine all day, and took some heavy hitting meds to knock it.  I *thought* at first it was just the meds kicking in and making me a bit woozy, then it got MUCH more intense, then everything started shaking and I realized it was an earthquake.  EVERYONE was freaking out?!  Ummm....  OK.  No damage here, everyone is fine :)  I'm more concerned about Irene messing up my weekend plans, LOL!
