It lit up the PNW seismographs a short time later:

A look at several sites' 6 hour charts shows the same noise pattern all over Washington and Oregon. Fascinating stuff.

Felt the quake here in Norfolk VA very strongly, the LARGE building shook, rattled steel sway braces in the overhead, shook the ground. Had one smaller shock, followed quickly by a major shock.

"Here" is Navy Base Norfolk, BTW. Area building is on is fill in the bay.

Epicenter was about 20 miles north of me. Good 45 seconds of serious shaking, a few things fell off shelves, no apparent damage. And here we are preparing for a direct hurricane strike in a few days...

Wow.... War, recession, flood, drought, tornado, hurricaine, earthquake.

Sure am glad I'm not president.

Weston me too! I can't think of a good reason to want to do that other than to sleep with Mrs Obama.

Why Weston? You could be on a 2 week vacation at a exclusive estate!No worries except on raising money for the next election..

Wow - we went from science to porn and politics in 5 posts. That might be a new HSM record.

Ahhhhh.... Thers's a difference between being president and being the president. I suspect that whoever were president would have his hands full about now. The other guy, the one Paris Hilton referred to as the "old wrinkly white guy", is probably counting his blessings at the moment. How he would have done is all conjecture at this point and not worth discussion. Discussion about the current guy becomes political and this is not the place for that. I'm just happy that I don't have the job.

Just consider it a practice run.., Have fun.

Read from a yooper (Upper Penninsula, Michigan for our off-shore friends) today that they got rattled a bit, too. That's about the farthest I've seen yet where it was felt.

Well, we just had another little after shock here; enough to rattle the windows a bit and make the dogs look up.

Damn! I was out riding my motorcycle and missed the whole thing.

Seems like an odd place for a large earthquake. The only geology that suggests them is the old meteor crater in Chesapeake Bay (http://en.wikipedia.org/wiki/Chesapeake_Bay_impact_crater), and the fact that Virginia rafted up against West Virginia to form the Blue Ridge Mountains that run along the state line and up through Pennsylvania.

My parents live in Goochland (suburb of Richmond) -- about 20 miles from the epicenter. My Dad said the house shook for about 20 seconds, but nothing fell off the walls.

My Mom was playing golf at the time. She said her 4-some paused until the quake was over, and played through :)

As the earth moved for her, she may enjoy another 4-some :D

Over here on the Eastern Shore, it only shook for maybe 5 seconds but I swear you could see the sine waves as they traveled through the ground and into the house! :eek:

Intertestingly, it was silent. I always expected there to be a real low rumble but nothing. (This was my first earthquake.) I guess the sandy ground soaked it up.

The Appalachians didn't grow from dirt water and sunlight...

People laugh at me for chaining up my compressed gas cylinders and chaining my ultra-top-heavy 50 year old drill press to the wall, but every time there's an earthquake, other than in CA, you hear reports of "never thought it would happen here"

Apparently, there are alot of small faults under central Va, caused when Europe pulled away from North America after the creation of the Appalachians. We get at least one small quake every year, including two in October last year. Not enough to actually 'get used' to it, but enough that you know what it is when it starts happening. This one was just way bigger than usual.

That will never happen here! :D

Around the "ring of fire" we associate quakes of that magnitude with active faults, many of which you can see at the surface. We also don't have the kind of bed rock that is common back east and which propagates earthquakes a long distance with little loss of energy, relative to our sediments and lava beds. Except for the New Madrid fault I don't have any specific knowledge of active faults back there and because it is a largely inactive area tectonically speaking, there's not much interesting reading. This article describes some very old faults. http://www.msnbc.msn.com/id/37407341/ns/technology_and_science-science/t/san-andreas-like-fault-found-eastern-us/. There's a good reason for thinking it will never happen there - at least not often.

Geologists tell us the Appalachians and the Blue Ridge mountains were formed 500mya when NA and Europe collided. The morphology is quite similar to the mountains pushed up by the Indian subcontinent when it collided with Asia. So yes, in a way, those mountains did grow from soil and water, and a bit of a nudge from adjacent plate.

Like BP's GOM well, the Macondo. Halliburton will catch blame for all the Marsellos frac work they seem to be doing.

Buy 'ol Hallie's stock, today, 'cause next week it'll be back.

welcome to my world from CA. I guess if you have never bean in one it would shock you. We get little 2'S TO 4"s all then time. The LA news was making fun of the east coast, about how they would not know how to handle one or the clean up. In one after 12 seconds I start to worry about it, but if Starbucks is still open every thing is fine. So if you have others go to a door way and hang on stay away from the windows they come at you, the most fun is if you are setting down you relay feel , the them and if you hear that trani sound that is not good . Good luck and glad no one was hurt Brett

I was sitting in my recliner talking to my friend Jon. I thought for a second that a cat must be under the recliner trying to get out in a panic. Then,realized everything was starting to shake.

A coupe of drill indexes slid off a bottom shelf onto the floor in my shop. Otherwise nothing was disturbed.

Last quake I was in was about 1968 in North Carolina,in an old house I was renting for $18.00,yes,eighteen dollars a month!!! For a shop. It was on a hill,about 8' off the ground in back,held up with spindly brick pilings about 12" square. The house suddenly shook very noisily. I thought someone was trying to tear the front door off its hinges for a second,then realized it was a quake.

We just don't get quakes here in the East.This one was felt from Georgia to Rhode Island though it was only a 5.8 or 5.9. The old,harder,deeper rock structure in the East transmits quakes a great deal farther than in the West.
