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:

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.

Earthquakes can be a lot more exciting on the upper floors of an office tower than they are in open country or a single story wood frame building. BTW, just in case this is a precursor to something bigger, the media should probably warn people that milling around next to a skyscraper covered with glass not necessarily the optimum strategy for safely riding out an earthquake.

At 1:55 in Dedham MA, just outside Boston, I felt the rocking for about 20 seconds. Very obvious that it was a quake.

I am in Richmond, VA. No damage but a lot of shaking.

That was cool! I’ve been in two earthquakes before: one (Maryland) was just a big Thump, nothing else, and in the other (San Diego) I was on a moving bus and so didn’t feel anything. It was great feeling the earth move up and down a half-inch or so for 5-6 seconds.
My wife’s been in much more serious earthquakes that she says began like that, but just kept building. Perhaps not so fun.

From MSNBC.Com
“No tsunami warning was issued, but air and train traffic was disrupted across the Northeast and mid-Atlantic”
LOL…LOL…and how would an inland earthquake ever cause a tsunami?

August 23, 2011 12:12 pm

Felt it in Greensboro, NC. Felt my chair moving underneath me and then saw liquid in bottles on shelves in my office sloshing around. Must have shaken for 20-30 seconds. This is the first earthquake that I have ever felt.

I am about 30 miles SSW from the epicenter. It was moderate and seemed like it lasted for about 30 secs. No significant damage where I am located. But, there is a Nuclear Power Plant very close that I understand was taken offline as a precaution. I’ve not heard anything saying that there is damage or anything to worry about as a result of the quake. We are actually joking about the ‘devastation’. I may need to go home a re-arrange my deck furniture… LOL.

Oh yes it is. Earthquakes anywhere is normal. But in some places they happen more often.

Hmmm! Felt that earthquake all the way out here in Colorado Springs about 12 hours early. No, wait, that must have been a Colorado tremor. Anyway, bet you that some dufuss is quoted in the MSM before today’s end saying that these quakes are due to global warming.

DC should be evacuated for several weeks as a precaution against aftershocks

Felt in Hickory NC. Thought a train was going by but didn’t hear the train!
Then realized it was the earthquake tremor!

here in manhattan NY, i was in a 9th flr conference room of a 40 story building. It was so mild, it felt like swaying in the wind. pretty kool. Enjoyed it… except for the fire warden constantly getting on the PA system, giving ittitating non-news, every few minutes.

August 23, 2011 12:33 pm

now if this had happened on 9/11 a few weeks from now…

> Why are you people sitting here making jokes. This is not normal.
5.8 (5.9, whatever) is significant. I checked various sources, found a tongue in cheek post in Wall Street Journal blog, and decided there wasn’t too much destruction.
This is not the first time a quake has shaken the Eastern Seaboard, and it won’t be the last. Instead of making jokes, what should we be doing, panicking?
Wait until New Madrid slips next time, near St. Louis. Won’t be much joking that day.

Actually Ric, the real joke may be on us here in New England if Irene’s path continues to inch eastward…
