From my friend Will in LA:
"Honestly, I just felt the floor wobbling. I stood up, realized I was sitting in a room with glass walls, and waited (away from the walls of course) for a minute until it stopped. Then I joined all my coworkers outside, and started posting my exclamations to Twitter."
Oh Will, always one to downplay a 5.4 earthquake.... Makes that picture he took when he was at Museum of Natural History a little eerie.
