Earthquake in NYC?

Just a few moments ago I was sitting at my desk and, all of a sudden, I felt the floor and the chair shake. The shaking wasn't very strong and it lasted for a few seconds.

What a strange sensation to fell the floor underneath you move/vibrate, even if it's ever so slightly.

UPDATE: Ha, it was an earthquake!
