I felt the quake very clearly here on Long Island, just outside of NYC. Though I've never felt an earthquake before, there was no doubt what it was.
I marvelled at the feeling for a moment, until I noticed that the house was shaking enough that the windowshades were hitting the windows. Then I decided to ride the rest out in my backyard.
Very odd.
That said, it confirms that we're doomed here in NY if anything really bad ever happens. JFK and Newark airports are currently closed, due to evacuations of the control towers.
Now, I'll go back to worrying about hurricane Irene.
