I felt it in Dover, Delaware, on the third floor of a three-story building. It lasted about fifteen seconds, and I bolted like a bat out of hell down the stairs and out the door.
The Japanese have a saying: In case of earthquake, run upstairs, because upstairs is a good place to be when upstairs becomes downstairs...
FYI from a So Cal native next time that the last thing you want to do in a quake..
It the crap falling off building outside that will kill you...stay put if you can, but get away from heavy thing that will fall... get under a desk, in a doorway, or in a bath room, again it the falling crap that will kill you...
FYI brick things in a quake like a fireplace chimney are pure death they can just shatter and go flying or crumble on top of you
