This makes the second quake I have noticed while sitting on that commode. The real third quake happened while I was in bed. It was much more severe, caused damage to the Washington Monument and National Cathedral.
The quake is rated at about 4.4 with a center below Dover, Delaware. Map shown in this article:

There are many ancient faults in the eastern USA. Most of them rarely call attention to themselves. We don't have the clashing of tectonic plates that are so well known on the west coast.

Epicenter was in central-north Delaware so the title is a bit misleading. I'm not aware of fracking around Delaware though.

I was working in Philly at the time it hit. I didn't feel a thing although a couple of co-workers mentioned that they did feel something. OTOH, I did feel the 5.8 quake located north of Richmond, VA on Aug. 23, 2011 while in Philly. Many buildings were evacuated for about 1/2 hour following that one.
