I bet a lot of people even here in the metro{if they don't already}are going to have some structural/foundation damage from this.

Shook me right awake and was quite alarming. Thought it had been a very close lightning strike but quickly realized there were no storms. This was the first one I've ever felt with an audible roar. Felt shaking for at least 20 seconds. Nothing fell from any of the shelves, luckily.

Looks like at least one house in SW OKC had some pretty major damage.

What is the significance of the blue highlighted area above?

I'm guessing that is a temporary radar image of all of the birds that took flight at the same moment. There were some other more localized video loops on social media.

That was the first one I felt at home. Just outside of Lexington and on top of a hill. Woke me up, knocked down a painting off the mantle and spooked the cat. The only other one I felt was a little rumble/vibration a few months ago at home and the big one a few years ago and that was at work near the airport

What is the significance of the blue highlighted area above?

Oh no, that's an approximate outline of the furthest out reports of people feeling it to show how large of an area people reported feeling it in.

Biggest one I have ever felt.

Same here. It shook faster, lasted longer and more frightening than the 5.6, 2011 quake. I was saying, "Please stop, don't get worse."

Just got called to go to work and check the buildings for damage. I can write the report from my couch. None. But there's records of entry/exit.

While it was frightening to go through, picture frames and vases didn't fall to the floor at my house from the Pawnee quake, so gotta keep hoping the earthquakes don't get more intense. The earthquakes underneath and very close to Stillwater have for the most part subsided this year. Hopefully, things will continue that way. My guess is the next big earthquake, meaning greater than 5.0, will take place to the WSW of Perry. That area has been one of the hottest spots for earthquakes in Oklahoma for quite some time. Fortunately, that area is well out in the middle of nowhere.

So basically nearly 1/3 of the continental United States felt this the other day? That's crazy. Kinda alarming.

The earthquake was moved up to a 5.8 after more analysis. Now the largest recorded.

https://www.usgs.gov/news/magnitudes-oklahoma-earthquakes-shift-upward

Well Stillwater just had 3 small earthquakes in 10 minutes.

I new it was stronger than the one a few years back. So I guess this 5.8 is a new modern day record?

Might be a lead up to a bigger one. Lots of houses have brick damage from the one the other day BTW.

I just noticed this evening, a small crack in my sheetrock has become a longer and much bigger crack. I wonder how many other people are getting cracking that is getting worse with each shake.

My guess at the next big one is Fairview since they have a had a number of medioum ones. Perry also as you suggest. If each new large one gets bigger, does that mean we are in store for say a 6.0-7.0? Can we say buildings falling down?? I doubt many have been build to seismic standards.

Just felt another one in SW OKC.

Just felt a small earthquake in Norman. It lasted about five seconds.

Indications are that it was a 3.8 near Spencer. I felt nothing in NW OKC.

9:05 here in Midwest City. I'm guessing in the high 3's but if it's an aftershock from Pawnee, it could be stronger.

We felt it at NW 178th & May. It felt like someone kicked the couch. Very short but sharp.

The OGS just updated their list and have it at 3.7. I emailed my friend in London and told her my guess was 3.8. Pure luck with a little bit of "educated guess" working for me.
C. T.

Felt it in NE OKC. Like corwin1968 said it was shirt and sharp. I thought my dog had slammed into the wall and only noticed it was a quake when my table had residual shaking. Much closer than previous quakes have been..

Felt it relatively strongly in S OKC, near Plaza Mayor. Like others said, it was a short, sharp movement like a quick shove. Didn't last long but both me and the fiancé felt it, and he misses most of 'em.

I'm curious, are these quakes spooking the CRE market in OKC? Or are most investment grade buildings built to seismic standards?

So I guess there is this too:

I'm certainly no expert. Someone at the TU forum the other day asked about coinciding earthquakes earlier on the 4th on the west coast and if they could have been connected to the one in OK. The "expert" quickly dispelled that saying that the plates in question are basically (somehow) separated around the Rocky Mountains and that there was little to no chance the events could have been connected.

My son lives in Scottsdale and on their news stations people in Gilbert Arizona claimed they felt our Pawnee quake. Gilbert is near Phoenix and is west of the Rockies. So who knows ?

That sounds like complete hogwash to me. EVERYTHING is connected.

Wow.

Two words: Plate tectonics.

Wow.

Two words: Plate tectonics.

Yeah but your main plates run near the borders of the continents or just in the ocens. Rockys were formed from the Pacific and Atlantic plates pressingagainst eachother. There have been major earthquakes in the past on the west coast that did damage as far east as Ohio (I believe the 1906 San Fran quake). It could have been felt.

I may have parsed it incorrectly. Can an earthquake be felt across plates? Of course. Does that necessarily mean that one quake had anything to do with another quake 72 hours apart and hundreds of miles away? Nope. The part I was replying to claimed it was hogwash that plates are "somehow" separated. It's not hogwash, it's literally the cause of earthquakes.

KFOR made a big deal about a 2.7 quake centered under Edmond. Such quakes are more startling for the sudden noise they make, rather than the shaking. The numerous quakes under 3.0 are why they don't get taken more seriously than they are in Oklahoma. KFOR sensationalizing such minor quakes doesn't help.

I watched them mention that quake on the 6PM news and never considered it to be sensationalized.

In the 5:00 hour they had a persistent graphic in the top left of the screen declaring the earthquake and that more details would be coming soon. I think they toned it down once they discovered it was a smaller quake.

Slept through the reported 4.5 earthquake in Pawnee last night, though widespread shaking was reported.

I felt it.

I felt it.

I did, too and heard my French doors rattle. Hopefully, earthquakes stronger than 4.0 don't get closer to Stillwater. The 5.8 one in the neighboring county on Sept. 3rd was plenty frightening enough. The closer ones have generally been staying under 3.0.

Fairly strong quake felt in SW OKC.

Mustang felt that one. A good shake, followed by a sort of sway/shimmer.

That was quite a shake!

That was a pretty good one up here around Rockwell and Expressway. I usually don't feel them but it shook my whole computer screen and tv.

Odd. My husband was upstairs and felt it. I was downstairs and didn't even notice. But I was also scurrying around taking down Halloween decorations and in motion at the time.

In SW OKC a mile from Hobby Lobby HQ. Felt it enough under my feet to know it was an earthquake. But nothing shaking in the house.

Same here. The long swaying afterwards was different.

Northwest Edmond. 1 jolt followed by shaking and then another stronger jolt then shaking that slowly diminished.

It didn't last long but it was definitely a good jolt.

very strong and very long here in Jenks

That quake was most certainly felt in Stillwater. It might have been about as strong as the recent 4.5 one.

Ponca, Tulsa and Wichita all felt it

5.3 near Cushing. That is up there.

http://earthquake.usgs.gov/earthquakes/eventpage/us100075y8#executive

Felt it easily near NW 122 and Council, OKC. Lasted longer than any of the others we've felt, with at least three distinct shocks spaced out during the lower-level trembling.

I live in Duncan. I was in the bedroom when I felt it. My husband was in the living room and didn't feel a thing. When I came out of the bedroom to ask him about it, he thought I was joking. I had to turn the TV on to KFOR to show him that yes, there really was an earthquake.

Just spoke to a relative who lives right on the Moore-Norman city limits line. He didn't feel a thing. Weird.

Does KFOR really need to have a "earthquake alert" on the bottom of the screen 45 minutes after the fact?

It has been downgraded now to a 5.0.

It happened near Cushing? Wow. Hope none of that precious black gold spilled...

Looks like some fairly bad damage downtown. Schools are closed and some have been evacuated. Yeesh......

http://www.kansas.com/news/local/article112994208.html

Also noticed that Facebook issued its "mark yourself safe" for the quake. Probably overkill for the OKC metro but it might help friends and family who hear of it stop asking folks here if they mark themselves safe, so maybe that's part of why they did it...

Just wondering today, what if we got a 5.0+ in the metro. I'm thinking close to downtown? I was in one of the medical buildings dropping of some records. Anyone know if any of the OU medical buildings are built to withstand shaking??

Wow, just felt a very sudden and startling earthquake. At least it didn't last long.

Update: It was gauged at 3.3, centered 8 miles northeast of Stillwater, early Thanksgiving morning. I thought it would be somewhat stronger than that. The quake comes from an area that has been active in the past and too close to Stillwater for comfort.
