Yup, I was at the epicenter. It was very, very, odd: there was a low-frequency and distant “boom” accompanied by an steady, powerfull, vibration felt through the building and the air that lasted for about three seconds. It did not sound like an explosion or thunder because there was no sharp “crack”; it sounded rather like someone had dropped and an enormous object on the ground far away. Afterward, it was unnaturally quite outside.

Michael Moore fell off a stepladder, perhaps?

My office is across the street from a construction site, so I probably dismissed this as equipment moving (makes my building vibrate). Would you consider this more or less noticeable than a steel beam being driven into the ground 60 yards away?

The feel of an earthquake can vary tremendously. The ones we get here in the 3 range are like a truck hitting the building. In the 5 range there is shaking and rumbling for about five seconds.
