Just heard on the news of a 5+ magnitude earthquake in the Washington DC area.
Hope everyone is OK.

Also looks like the current hurricane could get up that way also.
-
JFK Airport is closed because of it.
Even felt the thump up here !

5+ is nothing...
-
Southern Colorado had 5.3 yesterday. Yawn.

Time to get the T-Shirt making gear fired up.

Ain't that the truth, did my first 5+ in kindergarten. Everybody here is wondering what the hell is going on. Reports of damage but no injuries or the actual extent of damage. Felt like somebody bouncing on the floors or a helo hovering overhead briefly but lasted to long (about 5-10 seconds). The two local bridges are reported closed but other reports show at least one open.
It wasn't near DC, actually between Richmond and Fredricksburg.

Reports of feeling it in Clayton, Ga....northeast of Atlanta.

I won't say what I really want to say about an earthquake in DC. Besides, all the self importants are on vacation.

Yeah, all the people who need to be replaced were on vacation. Missed another chance.

Somebody posted on a local "news" website it was Bush's fault :)
-
It was felt in my area as well...not by me. I was driving at the time. My sister in CT called and said they evacuated her building. She felt it.

I think Cris Christie just jumped into the race.

Here's what it looks like from Cleveland's Museum of Natural History. Where the solid line stops on the right hand side and all those real faint squiggles are.

With 35+ years in SoCal (before I escaped) I've gotta agree with TAB on this one. I can generate a 5+ after a night of pickled eggs and home-made beer. Sheesh...

No argument here, I lived across the street from the Eel River in N. CA....the river bed IS the San Andreas fault line where it enters the continent from the Pacific. We had routine shakes of over 5 for the two years I live out there. They eventually had to abandon the Navy base on the cliff outside of Ferndale due to several very large shakes in the mid 90's.
When I was there, we had to monitor a crack in the floor of the operations room to determine if the cliff was going to fracture off into the Pacific!
Good times, good times! ;)

I work in Greensburg, PA and was on the 5th floor of the building in which I work. It was rather exciting for a non-Californian like myself and my co-workers. My wife was home with the kids and didn't notice anything at ground level.
-
Apparently, tw overnighted that dragonfruit plant to DC. Who suggested that again?
-
Supposedly it was felt along the Sunset Coast of Michigan, but I didn't feel a thing at work.
Of the 4 quakes that have hit my area that I can recall I have only felt one. The other 3 besides this one I think were caused by the New Madrid Seismic Zone. The NMSZ has been the cause of some of the biggest quakes in the US and if the big hits there again both St. Louis and Memphis will probably sustain tremendous damage.

Earthquake Summary
Three Main Shocks
December 16, 1811 - Magnitude ~7.7
January 23, 1812 - Magnitude ~ 7.5
February 7, 1812 - Magnitude ~ 7.7
A Robust Aftershock Sequence
Aftershocks are Earthquakes!
December 16, 1811 - Magnitude ~7.0
Six aftershocks in the first two days in the range of M5.5 to M6.3. Hundreds of quakes felt into 1813.
It's happened before 1811-1812
The geologic record of pre-1811 earthquakes reveals that the New Madrid seismic zone has repeatedly produced sequences of major earthquakes, including several of magnitude 7 to 8, over the past 4,500 years.
The New Madrid Seismic Zone is at Significant Risk for Damaging Earthquakes
This sequence of three very large earthquakes is usually referred to as the New Madrid earthquakes, after the Missouri town that was the largest settlement on the Mississippi River between St. Louis, Missouri and Natchez, Mississippi. On the basis of the large area of damage (600,000 square kilometers), the widespread area of perceptibility (5,000,000 square kilometers), and the complex physiographic changes that occurred, the New Madrid earthquakes of 1811-1812 rank as some of the largest in the United States since its settlement by Europeans. They were by far the largest east of the Rocky Mountains in the U.S. and Canada. The area of strong shaking associated with these shocks is two to three times as large as that of the 1964 Alaska earthquake and 10 times as large as that of the 1906 San Francisco earthquake. Because there were no seismographs in North America at that time, and very few people in the New Madrid region, the estimated magnitudes of this series of earthquakes vary considerably and depend on modern researchers' interpretations of journals, newspaper reports, and other accounts of the ground shaking and damage. The magnitudes of the three principal earthquakes of 1811-1812 described below are the preferred values taken from research involved with producing the 2008 USGS National Seismic Hazard Map (http://pubs.usgs.gov/of/2008/1128/).
The first principal earthquake, M7.7, occurred at about 2:15 am (local time) in northeast Arkansas on December 16, 1811. The second principal shock, M7.5, occurred in Missouri on January 23, 1812, and the third, M7.7, on February 7, 1812, along the Reelfoot fault in Missouri and Tennessee. The earthquake ground shaking was not limited to these principal main shocks, as there is evidence for a fairly robust aftershock sequence. The first and largest aftershock occurred on December 16, 1811 at about 7:15 am. At least three other large aftershocks are inferred from historical accounts on December 16 and 17. These three events are believed to range between M6.0 and 6.5 in size and to be located in Arkansas and Missouri. This would make a total of seven earthquakes of magnitude M6.0-7.7 occurring in the period December 16, 1811 through February 7, 1812. In total, Otto Nuttli reported more than 200 moderate to large aftershocks in the New Madrid region between December 16, 1811, and March 15, 1812: ten of these were greater than about 6.0; about one hundred were between M5.0 and 5.9; and eighty-nine were in the magnitude 4 range. Nuttli also noted that about eighteen hundred earthquakes of about M3.0 to 4.0 during the same period.

I live in NE Ohio and was upstairs @ my computer when I felt it! We live near RR tracks and I thought a train was going thru but then realized it was a very different movement. Much more than usual. Didn't think anything of it until it was mentioned on the news.
Hope everyone is safe.

I live just outside of DC in N.VA. I was upstairs in my house and thought a big truck was in the street unloading something. No damage but some shaking for 30 secs or so. Traffic was horrible as the Govt was let out early.

Via Sheriff Jim Wilson:
THIS JUST IN: The White House has just confirmed that the earthquake occurred in a location called "Bush's Fault." We might've known!
-
Son called me at 2:00 today, from just North of Charlotte, NC, felt it, and said the dogs freaked out for a bit...

Sad but true, us Eastcoasters don't know what to do with 'dem tremors.........Close the airports? Evacuate buildings?
Really?

Obama also announced that the Secret Service and Maxine Waters continues an investigation of the quake's suspicious ties to the Tea Party.
Conservatives however have proven that it was caused by the founding fathers rolling over in their graves.

It's just the Dow tapping down to the bowels of hell on Wall Street.

UPDATE: The east coast earthquake apparently was caused by an unknown fault line running under D.C. and through Virginia. It is now being called Obama's Fault, though Obama will say it's really Bush's Fault. Other theories are that it was the founding fathers rolling over in their graves or that what we all believed to be an earthquake was actually the effects of a 14.6 trillion dollar check bouncing in Washington.
