Just back from another walk. A house on the next block lost the top of its chimney. Several instances of cracks in masonry.

DC is 80 miles from the epicenter.

Also interesting is the thought process everyone I talked to went through during the quake. Not one person I've talked to immediately thought: "Earthquake!"

That was maybe the 3rd or 4th possibility that came to their minds. If there was any construction project nearby, peops tended to think the shaking was related to that. One friend of mine in Virginia thought something had fallen on her house.

2nd or 3rd possibility was: "Terrorism"

Finally, after checking the Internet: earthquake

There are now news reports of pipes bursting, ceilings falling, at least one residential building in Maryland condemned.
