I agree that people are getting more used to them, but it is ridiculous for the state to do nothing about it man-made earthquakes. Oklahomans' are basically subsidies the companies producing the earthquake by buying their own earthquake insurance and fixing the damage on their own dime. Not to mention that ODOT has push out much higher earthquake standards for bridges, which will significantly increase the cost of road construction throughout the state. All because we are unwilling to pass a law saying you can't run injection wells near faults.

Another good sized one just rattled me in my office in East Edmond near 15th and I-35. I think that's the third one I felt today - with this one being the most significant.

The state's nonchalant attitude is going to catch up with us one day.

I really hope this wasn't a fore-shock and was just another good sized quake. O well at least we know our politicians will keep repeating what the oil companies tell them to. I guess if you keep repeating the same lies over and over again you can convince yourself that it's true.


M4.1 - 13km NE of Edmond, Oklahoma (http://earthquake.usgs.gov/earthquakes/eventpage/us10002l0a#general_summary)

I don't think I'd be very concerned that quakes of 4.0 or over are a cause of concern for a greater quake coming until they go over 4.5, since 4.7 was the foreshock of what came before the record breaking earthquake of 5.6 in 2011.

They sure seem to be getting stronger at my house east of I-35 and Waterloo. The 4.1 is the first one to knock stuff out of my buffie . If the number of quakes keeps going up, what will it be like in another year? I'm thinking that we may get a real big one soon, I'm not talking 5.0 either.

Remember the consequences of a 7.0, which is considered possible. From another thread:


A 7.0 quake that with our building standards would be equivalent damage-wise to a 7.8 -8.0 quake in cities on the west coast. The talk of USGS using words like "catastrophic" should be taken seriously. The extremely rare Earthquake Warning that was released (and quickly pulled!) should tell us everything we need to know.

People must realize the power of a 7.0 quake on the Richter Scale. A 7.0 quake would be approximately 75 times more powerful as the 5.6 quake we had in 2011. Can you even imagine 75 times more powerful? 5.6 to 7.0 doesn't sound that much more, but that's the Richter Scale at work. That's why they're using words like catastrophic.

I really think the oil companies could remedy a lot of the problems by building a good sized pipeline out of the heavy fault zone area and move the saltwater 50 miles West and inject where the quake activity is non-existent.

Up to 17 and counting since about 1030pm about an hour and a half in north east Edmond. This is going to be a long night. I might go out and sleep in my truck. (single cab Ford Ranger) grrrr.

This is why we should not waste a dime on shoring up the capital or any meeting place of our state legislature. maybe a few pieces of cement bouncing off their heads will outweigh the payoffs from the energy and drilling industry.

They keep coming all night long so far. I cannot get much sleep because of them. This is the worst that I've seen. I grew up in California and this is worst in total number in a short period of time.

I don't expect the oil companies to do much of anything on their own about the earthquakes. Because to do so implies they are the blame for them, providing evidence of liability for lawsuits against them.

Dang, another earthquake just happened in Stillwater, and it was definitely stronger than the 2.2 from last night that centered a mile from Stillwater. Even the news guy on Channel 4 just said he noticed it! It will be interesting to see how strong this one turns out.

It was just a 3.5 centered on the far west side of Stillwater. But gives Stillwater people too good of an idea of what people living between Guthrie and Edmond have been going through.

Some Facebook comments about the earthquake made from Stillwater:

"The whole Walmart shook! I told my Kids it was momma's fury cause they wouldn't listen! Lol"

"That felt much bigger than a 3.5!! It shook like crazy on the 3rd floor of the life science building!!"

"Holy earthquake batman."

"My apartment shook like crazy! Scared me for a second!"

"Felt really big all the way out here on Airport Road. This is a brick house and it shook the Crap out of it. Lol"

"It sounded like field artillery."

"HUGE quake just hit us in Stillwater! Three booms coming from far away and then in. I was on second floor of home and the whole place continued to move for FAR TOO LONG and felt like it was coming down. We have allowed them to get away with this too long. As I was reeling sideways I noticed our dog Berkeley leaping straight up in the air in alarm. Get those law suits in. It is all they understand."

"It really scared me. There was a loud explosion and the house shook. It lasted longer than other quakes that I have previously felt."

"Hardest one we have felt downtown. Got to stop the disposal and injection wells."

"Was in the middle of seeing my very last patient. Underscored exactly why we are leaving Stillwater."

"Whoa that was a big one at Boomer Lake, 12:15. We had one last night too that shook the house about 9:30 or so."

That one a few minutes ago felt like a 4.5+

Felt that downtown for sure! @3:20pm

People in my building even reported their cubicle walls shaking and I somehow missed the entire thing. I'm a little alarmed at how absent-minded I apparently am.

Felt that one in the OUHSC complex near downtown. All of my coworkers - even ones that never seem to feel earthquakes - felt that one. Wow.

yeah... felt a pretty good jolt here just east of downtown. -M

I didn't feel it in Stillwater and glad a stronger one than usual centered well out in the middle of nowhere where only mostly coyotes, deer and cotton tail rabbits can feel the full effect.

Felt in The Village/Quail Creek area.

I felt it at my house in East Edmond. My wife called me from downtown and said they all felt it in the 100 Park building.

Nice one downtown just now. 1:12pm

Felt it in Moore.

That was the longest earthquake I've ever felt! Two good jolts and lots of rumbling.

That was the first one I've felt from the 15th floor at my new job. Pretty weird feeling.

Longest here also, and the Tulsa seismogram peaked out. Anyone have a strength rating on it yet? Didn't feel like the two 5+ ones I've experienced, but definitely stronger than 4.0 I think.

I'm at NW 122 and Council in OKC, btw...

The first report I'm seeing says it was a 4.0 centered close to Crescent.

Wasn't that the one about 30 minutes earlier?

Wasn't that the one about 30 minutes earlier?

Yep. at 12:48

wonder how big the last one was, it shook pretty good here at the airport

4.5 at Crescent at 1:12 PM

wonder how big the last one was, it shook pretty good here at the airport

USGS is reporting it was a 4.5 6km NNE of Crescent

Was at work and didn't feel a damn thing...

Must have been daydreaming.

Strong in NW OKC - building made quite a stressful noise.:Smiley127

Wasn't that the one about 30 minutes earlier?

I didn't feel anything earlier so I'm not sure. You could be correct.

Big one, felt it Downtown on 1st floor. I would hate to have a structure anywhere near the line is.

Felt it in Mustang. Two 4+ close together made for a long shake.

Probably the longest one I've ever felt. I would say it was about 15-20 seconds of shaking.

Okies sure get shook easily.

The Tulsa seismogram at the top of this page indicates that it took five MINUTES to settle back down! (scroll the image to the right to see it; took me a long time to discover this.)

Wowser! That felt larger or closer than the one this afternoon from over here by Lake Overholser.

Another M4.5 centered in Crescent, OK. Yeesh ... definitely the biggest day we've had around here in a while. I wonder if they're foreshocks for a larger event or if our earthquakes are just gradually becoming stronger and these may be the new norm soon.

Looks like 9 4.0's or higher in 60 days and 8 total in the five months before. Probably not a fair statistical comparison on such a short term but will see if that is an upward trend.

Both the Meers and Tulsa seismograms at the top of the page show very unusual patterns for a bit more than two hours, early in the evening, before the second shake. Anybody know what those might indicate? The swings are not nearly rapid enough to be actual quake traces, but since both graphs show the same behavior at the same time although the instruments are almost 200 miles apart and in very different geologic areas, I can't think it was some sort of local disturbance. 'Tis a puzzlement...

An interesting KFOR report which shows video from a Crescent grocery store at the time of the earthquake.

Very early this morning (about 03:20), I heard an extremely loud explosion in NW OKC. Only saw one other person report it on Twitter. Can't find any info about it. How would I check the seismographs for this time? Was curious if anything registered. This was loud! Anybody else happen to hear it?

Or this: Oklahoma Earthquakes (http://stillwaterweather.com/okareaearthquakes.php)

After slacking off some, the earthquakes have been stepping it up in frequency for the past several days. At least they're still strongly tending to center out in the middle of nowhere and far enough away from the city limits to probably not be felt by a lot of people, unless they get extra strong.

4.4 up near Langston about 15 minutes ago. Some report a pretty sizeable jolt on social media.

M4.4 - 8km W of Langston, Oklahoma (http://earthquake.usgs.gov/earthquakes/eventpage/us200041bv#impact_dyfi)

Wow, someone is reporting an earthquake on here for the first time since last August. I sensed it.

And it looks like a *second* one about 11:35 this AM just a bit NW of that previous one near Langston...looksl like the first one had a pretty narrow range of impact - you either felt a pretty good jolt or nothing. But I sure felt it here in E OK County.

M3.4 - 9km NE of Guthrie, Oklahoma (http://earthquake.usgs.gov/earthquakes/eventpage/us200041cz#general_summary)

Still not powerful enough to have any governmental authority able to regulate the activity that causes them. Weak sauce.

What would be strong enough? Killer quakes?

Wrong - IIRC, the Oklahoma Corporation Commission has the authority to regulate SWD's within a 6 mile radius of any 4.0 or greater earthquake. I know of several instances where SWD wells that have been impacted - here's an example from this past September -

It appears the CC only has the authority to ask "pretty please" in their requests.

Legislators hear updates on earthquakes, links to energy production | News OK (http://newsok.com/article/5457264) (10/31/2015)
Since March, staff at the Corporation Commission's Oil and Gas Conservation Division have issued six rounds of voluntary directives to disposal well operators to change their operations in areas of recent earthquake activity.
At various times in the past several months, Murphy's colleagues on the commission have publicly expressed reservations about its authority to require disposal well operators to shut in or reduce depths or volumes in response to concerns over man-made earthquakes.

The oil and gas industry largely has cooperated with the voluntary directives on induced seismicity. But a crack showed in their unified front after a small Tulsa company, Marjo Operating Co. Inc., challenged a directive in Payne County earlier this month

Im up at the francis tuttle in Edmond and it just felt like a bomb went off inside. Should be in the high 4's if I had to guess

huh... didn't feel anything near downtown. -M
