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 an after shock here in raleigh, nc. even though you could barley feel it, it was pretty scary. i mean, we’re not near a fault line, right? i don’t know, between all these earthquakes and to top it off with the hurricane hitting the NC coast this weekend, im a little freaked out.
Tony ,
Are you associated with the Lawrenceville School ? If so , I ‘m pleased that someone there reads this blog – and a little surprised too .
REPLY: No I’m not – Anthony
CAN ANYONE SAY “FRACKING” JUST THINK ABOUT IT I KNOW ITS GOING ON IN VIRGINIA
Earthquakes occur on the east coast more than people know or think. The “big one” was due sometime in the next few years–so it just happened today in the afternoon. I am in Frederick MD and did not feel the quake as I was outside in a parking lot of a store. But my husban was inside our house. The house is very well built recently (an energy efficient structure of wood) and the house swayed a lot. No damage to the house.
Charleston SC had a 7+ in 1886 that nearly destroyed the city. It was a long an old transform fault. Giles VA had a 5.7 in 1930’s (different fault). The Richmond basin has numerous small quakes. This big one doesn’t surprise me. But better them than me (my house is next to an old, old fault).

> Why are you people sitting here making jokes. This is not normal.
Yes, it is a normal human reaction to joke about something that could have been a disaster but wasn’t, or to cope with terrible events through which one has had to function. Medics, Fire Service folk, etc, tell awful jokes to release stress.
Also, there was a degree of over reaction in places like Washington, that raises a wry smile given their over reaction to many things, including imagined problems like CAGW …
CAN ANYONE SAY “FRAkKING” AS IN FRAKKING IDIOT???
I’ve lived in Virginia all my life and have felt many earthquakes. Not a big deal but this one really shook the house and knocked things off shelves, dressers and counters.
Distinctly felt it in Columbus OH. But then I’m on the 4th floor (of a brick building), which may have amplified it somewhat. We had similar vibrations in our building from adjacent construction activity a few days ago, but without the sway.
I like Docattheautopsy’s theory (11:05) that it was caused by the rapidly growing burden of the debt!
The lastest revision has the depth at 0 km, what are the implications of that?

it was fun! But did not last very long. Did you see the damage done? http://jmckinley.posterous.com/dc-earthquake-devastation
I am only 35 miles from the epicenter.

> Actually Ric, the real joke may be on us here in New England if Irene’s path continues to inch eastward…
I have a daughter who lives in Maryland a ways south of DC. Pretty much where the NHC expects Irene Sunday AM. I posted a Facebook note that I might come down for a visit this weekend, then amended it to say I should have been down this afternoon. 🙂
It will be an interesting weather weekend….
My mom felt it 350 miles away in western NY state near Buffalo. Set a chandelier light on the front porch to swinging back & forth. Said it was only the second one she ever felt. Last one was in the 1940’s.
Maybe the Mayan calendar running out in 2012 really does portend something…
NAH!!! Couldn’t, could it?
Dahlgren VA – Did not feel it 🙁 I was running on a treadmill at the time, and apparently kept on running without even noticing what was going on. I came back to work after my break to find my building evacuated. Fortunately, no damage to the house except for about a dozen wine glasses that had fallen off a shelf.
Oh, and just an FYI – while relatively rare, we had a 4.5 back about 5 years ago. So not that uncommon. (I am in va).

Give the USGS more time to figure that out. The latest I saw was 6 km for the first quake (a reasonable depth) and 0 km for the aftershock. They may also refine the magnitude a bit.
And I thought it was just one of those heavy duty pre-nap twitches.
Didn’t feel it here in western Quebec
As they are saying on Fox News. This earthquake hit the largest concentration of reporters in the US. Therefore it is a major earthquake.

The implications are staggering. A rising earthquake! First it was 4 miles deep, now it’s at ground level… headed for the troposphere, perhaps?
This could be another fingerprint of global warming.☺
[PS: Didn’t feel it in NorCal. Felt plenty of others over the years. Loma Prieta comes to mind.]
CAPE CHARLES, Va. – Geologists drilling half a mile below Virginia’s Eastern Shore say they have uncovered more signs of a space rock’s impact 35 million years ago.

Rock is on the move !
Quadaffi strikes the pentagon with his earthquake machine. 🙂
All quiet in Baltimore. I heard they had a little damage in one of the older neighborhoods, but, I live in a 100+ yr old building and didn’t have any damage. If you’ve ever seen those shows with an earthquake simulator, that’s exactly what it was like, but less so. I’m in a tall building, so, the lateral thrust really rocked the building. I heard the quake was very shallow (~.6 mi). Don’t know if that’s unusual for an east cost US quake.
LOL…This is too funny…I know that earthquakes are not as common on the east coast, but c’mon….evacuate??? LOL!! Oh and about what Bryan said: Brian says:

Wait until New Madrid slips next time, near St. Louis. Won’t be much joking that day.
They’ve been talking about California sinking into the ocean forever; the big one is coming; etc. They can’t predict an earthquake, its size or where it happens. So I wouldn’t be surprised if New Madrid stays in tact for the next 100 years. Probably won’t see it in your lifetime.
Just some words of advice to everyone out there….be prepared. Stock up on emergency supplies just in case. Whether its an earthquake, flood, hurricane, or whatever. It never is a bad thing to be prepared.

“DC should be evacuated for several weeks as a precaution against aftershocks”
I’d rather that we simply quarantine it as a precaution against politicians.
