It woke me up. Did anyone else feel it?
I was in class at the time. The classroom shook a bit and the people in my class broke out into pandemonium, as if something horrible had just happened. To make it worse, the university declared a state of emergency and sent out a pile of emails to everyone. I'm sure if I hadn't taken my phone number off their system the last time they sent out a robot phone call to tell me it's snowing then they would have called me, too.
As for myself, it just reminded me of back home in western Maryland, where if you feel the ground shake it just means the strip mines are blasting again.
edit - thought I'd add that perhaps the only damage done in the earthquake was done in my lab, where our laser beam for trapping cesium atoms was moved just enough to mess up the trap a bit.

There was a building on the OU campus that had some cracks in the wall after the earthquake.
I didn't realise earthquakes occurred that far east?
Saying that, we also get earthquakes here (http://news.bbc.co.uk/1/hi/england/7266136.stm).

One of the most active faults in the country is the New Madrid Fault, which stretches through southeastern Missouri and northeastern Arkansas. When the "big one" hits, Memphis will likely be toast.

Yes. The series of earthquakes in late 1811 and early 1812 are speculated to be the largest earthquakes ever in North America.

Here is an map of damage zones from similar magnitude earthquakes in Los Angeles and New Madrid.

P. S. I have experienced earthquakes when I lived in Baltimore, MD and Akron, OH.

According to the article I saw in the Norman Transcript, those cracks existed before the earthquake.
Someone on the mailing list Canroads posted the following url to a CNN article or blog http://ireport.cnn.com/docs/DOC-501263 about a big crack in the Earth in the Upper Michigan appearing from nowhere.

There is also another fault or line known in Eastern Canada and Northern New England, the Logan fault separating the lower plains of St-Lawrence river valley and the Appalachians and continue under the St-Lawerence and separate the Appalachians from the Canadian shield http://geoscape.nrcan.gc.ca/quebec/upperlower_e.php http://geoscape.nrcan.gc.ca/quebec/eq_e.php However another fault caused by a fracture of the Canadian shield the Neuville fault is also a factor as well as some or some grabens like the Ottawa Graben (Ottawa was shaken by an Earthquake in late June 2010 and it was felt even to Detroit) or the Saguenay graben http://en.wikipedia.org/wiki/Ottawa-Bonnechere_Graben
Is everyone ok up there? Hopefully the damage wasn't too bad and wishing everyone a quick recovery from the big earthquake.

Hahahaha...it wasn't bad at all. It woke me up out of bed, but didn't do much if any damage in Tulsa. It might have caused some very minor damage in the Oklahoma City area, and a guy fell off a ladder when it hit and received non-life threatening injuries, but it was a pretty small earthquake. It could have been a hell of a lot worse.
That area of Oklahoma is surprisingly geologically active. Small earthquakes happen often. This one was the biggest earthquake in Oklahoma in many years.
I dust-off this topic if it's ok for you.
Seems they had recently some earthquakes in eastern Oklahoma from what I read on other forums

We had 3 "major" (4.7-5.6) earthquakes earlier this month. I felt all three, and the second one was definitely the strongest. It sounded like my apartment building was going to shake apart and there was a low rumbling sound. A computer stand swayed back and forth but nothing fell off the walls and no dishes broke. It lasted perhaps 45 seconds, there were groups of waves that could be felt. After it was over there was a weird smell similar to oil burning. I didn't get scared at all. It was kind of neat to be honest. But I wouldn't want to be in a big one.
Yeah, the biggest one that hit woke me up. Other than the bed swaying quite a bit and the picture frames on the wall rattling, it was fine. Apparently one of the aftershocks hit while I was at work walking around and I didn't notice it.
The 5.6 earthquake caused some damage to Nielsen Hall (the physics building) at the University of Oklahoma. The ceiling tiles in the atrium room fell on the pendulum in the room, damaging the pendulum.
We had a 4.3 at around 2am last night and a 4.4 a little after 9am this morning.

I remember a few years ago when there was a 3.x or so quake in New Jersey. I was sitting in my computer chair when it started to shake, which caused a bit of dizzyness. I got up and the floor was shaking, and as soon as I realized what it was, it was done. If there were aftershocks, I didn't feel them.
I guess it's proof that earthquakes can happen anywhere, even if you don't live on/near a fault. Same with tornadoes. Had a couple of those last year and the year before... none in my area luckily.
If there's ever an 8.1 earthquake, blame it on Microsoft.

I was sitting on the 9th floor of my office building when it shook. Naturally, everyone wanted to head to the elevators and do the exact opposite of what someone should do during an earthquake.
Well a 5.1 happen near Anaheim on Friday Night.

Eastern North America. Alaska had a 9.2 in 1964, which trashed Anchorage and many other communities in south central Alaska. Hawaii (part of North America only politically, not geologically) had a 7.5 in 1975, which fortunately only caused two fatalities. And of course many other earthquakes in the Pacific coast states would be at least competitive with the New Madrid quakes, though at least those states are more earthquake-ready than the Midwest.
Seems there's also some seismic activity along the East Coast around NYC like one in 1884

I wonder if it might gived some inspiration for a tv movie titlted "Aftershock Earthquake in New York"?
Charleston in South Carolina was hit by a 7.3 earthquake in 1886

I still have memories of the 1988 Saguenay earthquake.
Update Yellowstone had a 4.8 Quake last weekend.

What exactly are you
supposed to do? I don't recall being taught in school "if there is ever an earthquake do this...", but I remember being taught about what to do in a tornado or hurricane. I think I recall reading that the best thing during an earthquake is to hide under a table? Or is that a tornado? Crap.
Regardless, running for the elevator is a
terrible idea during a 'quake, especially if it's bad enough that the elevator platform can plummet straight down into the depths of the shaft.

Well, both. Basically, you just want something to protect you in the case of failing debris. Even if the table collasped, it would be a short drop onto your body/head, not several feet.

Hopefully the safety features within the elevator shaft won't allow this to happen. But...it could get stuck in the event of a power failure. If that's the case, it probably won't be the only power failure in the area, and it could take a while to get rescued!
Really, there's no reason to go outside: Things could be falling from buildings; power lines could break, etc.

Funny story about that: (slightly offtopic)
When I lived down in Florida, there was a hurricane that hit while my family was vacationing near Miami. We were in a hotel. We were going to attempt to drive away from the storm (back to Orlando), when my family got into the elevator. It died a quarter of the way going down. We were stuck in there... for a few hours I think? I think I was about 4 years old at the time, maybe a year younger. Not very fun. It got hot as fuck in that elevator and I think that's where I got the fear of claustrophobia (the elevator wasn't actually as big as some of the ones I've ridden in closer to today) because goddamn it was CRAMPED in there.
I used to say I would never ride an elevator again. I broke that promise too fast. Elevators are too much fun.

Dang Chile got hit by an 8.2 quake. I remember Chile was hit by an 8.9 Quake in 2010 within the same area.

Strange, I can't find any hurricane in that area in 1996 or 1997. Maybe it was hurricane Erin in 1995, but I believe it's too early.
Back to topic, there have been destructive earthquakes which weren't that intense, like the one that hit Lorca (SE Spain) in 2011 which was a 5.1 one. I have never felt an earthquake, though sometimes a 3.0 occurs in my area.
Chile holds the record here, with a 9.5 earthquake in 1960.

I felt the 4.3, but I just thought it was somebody running up the stairs.
I was woken up by the 4.3 this morning.

Are you back in Norman?
I recently read an article concerning the increased seismic activity in the OKC area. If I recall correctly, it said that it may be induced by natural gas drilling, and that waste water disposal wells may be lubricated previously unknown and/or inactive faults.
This has been happening in North Texas, also.
We used have very few earthquakes. They were unheard of in my area; though there was a 3.something in Valley View Tx in 1985.
Then, all of a sudden, in 2008, there were 3 close together in time in the DFW Airport /Irving area. The biggest was 3.something and was strong enough set off car alarms. it kept going from there, but the activity has been more concentrated in different areas at different times.
In Parker County, west of Ft Worth, in the last few years, there was a swarm of probably hundreds of earthquakes. They were occurring daily for a while.

Chuck Scarborough wrote the book "Aftershock" in 1991
The threat of an earthquake destroying New York City is a real possibility, according to the experts. Although it takes nearly 100 pages for the disaster to finally strike, once it does this novel by NBC-TV anchor Scarborough picks up pace and never lets down. The aftermath of the quake of 1994 is a nightmare, much worse than San Francisco, with people trapped in buildings and subways, on bridges, and in tunnels. Electricity is out and looters take to the streets. Domenico Rizzo, head of New York's largest crime family, quickly moves to exploit a city in chaos. Sam Thorne, earthquake expert, is a vital cog for the rescue operation. The mayor's daughter tries to lead a group of survivors out of the subway. A large cast of characters, including squabbling politicians, almost overwhelms the reader, but the author basically manages to juggle their stories creditably and keep the tension high in this rousing tale
I have the book and the DVD: the Book is better, the movie can standalone and has only about 5% of the story and characters from the book.

Yeah. The shaking was pretty noticeable in Norman. I ended up having to guide our new graduate student through realigning the optics in the experiment, since it was enough to move them.
On CNN today (6.14), on the crawler, they reported two more earthquakes, a the biggest being a 4.something. They also stated that recently OK had more earthquakes recorded than CA. Imagine if you told somebody in the past that this would happen, they'd've ssid "no effin' way!"
I read that Oklahoma has had more earthquakes so far this year than the other 49 states and the DofC. Why the fuckety fuck is fracking still legal? It has been scientifically proven to cause earthquakes. Governor Failin' and the other clowns in Oklahoma's state government are so pro-business that they will put the welfare of the entire state in danger just so these companies can make a quick buck. It's disgusting. What will happen if we have a 9.0? Those natural gas companies won't be able to make any money if their infrastructure is ruined. Knowing the Oklahoma state government, they will allow fracking to resume once the aftermath of the earthquake is over.
I finally experienced my first earthquake a couple days ago in Juneau, AK. There was a 5.9 about 100 miles west and I woke up in my hotel room at 3 in the morning with everything oscillating back and forth. At first it was confusing, then it was briefly concerning, then it stopped and became amazingly cool.
It was sort of a fun ride and it didn't cause any damage other than wiping out the internet for most of Southeast Alaska. Apparently some underwater cable was severed. Here's the stats from USGS.

This was perhaps a mile north of my house. I felt it very clearly, but am surprised it wasn't stronger, even at such a low magnitude.
