I'm from NJ here :) Everyone I know felt it.
I was just sitting at my computer desk, and suddenly the desk, laptop, and TV all started shaking back and forth. It was scary.. But it only lasted for... 40 seconds...?
The funny thing is, is that the moment it happened, I immeadiately thought: "EARTHQUAKE!"
Also, has anyone else felt aftershock? Because the thing we felt was the actual earthquake itself... No signs of aftershock... yet.
