If you felt it, you can report is here to USGS: Did You Feel It? – Report an earthquake

There’s an earthen dam near the epicenter, 1.7 miles away, I wonder how it fared:

Felt it in greenville, sc but it wasn’t felt in seneca, sc which is about 50 miles west. Seems it ran the east coast both north and south a large distance.

In Laurel MD…everyone cleared the buildings where I work. Being quite the EQ novice I was quite concerned. We all knew what it was but were thinking, Here!?!
The floor sort of felt liquid and the cabinets were rattling. I don’t think I want to experience anything stronger than that unless I’m outside.

I think it was a planned quake by the UVA so they can claim to have lost all of Michael Mann’s emails and research /sarc

Man, new release shows it was only 1km deep! No wonder it was felt so widely. It’ll be interesting to hear what casued this. I can’t remember anything this magnitude on the east coast.

Felt it in Buffalo NY. It felt similar to one last year that originated in Canada.

felt it in the little town of sayre, pa about 15 mins. ago

We live in Montpelier, just east of the epicenter. It was pretty exciting. Everything shook, lots of rattling dishes but no damage at our home. I can’t believe the over-reaction in DC and NYC.

Hey I felt it in Stowe, Pennsylvania. We’re about an hour outside of Philadelphia.

Felt it in Southwest Michigan. Our building shook for several seconds.

OK, I give up… How is Obama going to blame this on Bush?

August 23, 2011 11:23 am

Experienced it here in Richmond, VA. Never been more frightened in my life. Things fell from shelves. The whole house swayed. Sounded like a freight train coming through the neighborhood.

The missus said her office building in SE Michigan swayed. She also felt something last night, and I told her that it was probably an earthquake…

August 23, 2011 11:24 am

Felt our office building move in Downtown Louisville, Ky. 20 minutes. ago.

August 23, 2011 11:24 am

Did not feel anything here in the Mid Hudson Valley NY. Obama says it’s Bush’s fault. No pun intended.

Web-based news is often very, very fast.
A few years ago, one reader on http://www.freerepublic.com wrote in that he had observed the shuttle breaking up, throwing strange contrails as it passed overhead of his office in Dallas. We read that story (live, worldwide) before NASA even knew the shuttle was in trouble back at the landing site – since they were not expecting any radio signals from it att the Cape until interference from the re-entry comm lockout was silenced several minutes later. Obviously, tragically, the astronauts were never heard from at all ….

Felt it in Gordonsville Va. 16 miles from epicenter. Never felt one that strong before. Rare for this area.

Don’t trust Fox sensationalist reporting … they’ll have it up to a 9 before they get real… oh how they love bogus headlines!!!

Felt it here in St. Catharines about half an hour ago (say around 2:00). Very mild, but I could feel it, see the table lamp shaking, and hear things clinking in the pantry. I tried to report it on the site you linked to, but their list of cities for Ontario don’t include St. Catharines — or Windsor or Toronto for that matter.

I was sitting in chair here in Everett, MA eating a late lunch and I felt nothing at all but many in Boston say they felt something. Is there some kind of geologic disconnect between here and Boston only 10 miles away or am I just .. “unfeeeeeling”?

Didn’t feel it here half way between Ottawa, Montreal.
We did feel one from Colorado about three years ago…shallow one as well, if I recall.
We had a couple of small ones as well off the Laurentians ridge in the last couple of years, that we felt.
One went on for about 30 secs. but wasn’t too violent.
