That Tulsa seismogram.

Whew, a very noticeable earthquake in Stillwater around 2:45 PM. It only lasted around a second and made my French doors rattle. It might have been a bit stronger than usual, so it will be interesting how USGS or OGS puts its strength. Interesting, it didn't come with a loud noise. Instead, it was one of those types that come with a sound like a sudden gust of wind.

OGS has the earthquake in the hot spot south of Perry. It's 3.5, so not as bad as the Cushing one yesterday.

Felt something here at the airport about 5-10 minutes ago it rattled the building, don't know if it was an earthquake or not

I felt it too, in central OKC (I-44/23rd St). Mild but lasted quite a while. My computer monitor was visibly shaking and I could feel it under my office chair.

We felt it here at sw 104/MacArthur. Didn't last long but was good little shake

Twitter was crazy with people talking about it, so I would say...yes.

OGS - 4.5M
USGS - 4.3M

Near Cushing.

Felt it at 63rd and nw expressway. Mild but longer than normal.

Missed it again in Norman. LOL.

A new hot spot for Oklahoma quakes, most interesting for venturing to a different part of the state has popped up. It goes further into nw Oklahoma near Mooreland, or to the east of Woodward. Frequent earthquakes there for the last week have contributed to keeping the level of earthquake activity well up more than any other area. I wonder if some oil drilling recently started there.

The Edmond-Guthrie area remains active with the nearby Langston area trying to get more active after a lull. Hot spots also continue northeast of Stillwater and north of Enid. The hot spot just to the south of Perry quieted down only to be replaced by a new hot spot to the wsw of that town. The Cushing area has fortunately quieted down, considering how a 4.3 had happened there.

Next thing you know . . . Oklahoma might be the next Yellowstone.
After a few million years . . . and with fewer scenic waterfalls . . .

Can someone update the OP with the earthquakes for September?

4.1 earthquake between Perkins and Stillwater Sunday afternoon, 11/9/14. With help from a renewal of earthquakes near Anthony, KS, Oklahoma area earthquakes have been increasing somewhat lately in frequency.

big shake in east edmond

Felt in downtown OKC

Just felt it here in my office in Norman. Came here immediately to see if anyone else noticed something.

Felt in downtown OKC

And at Reno/Portland.

I didn't feel it in South Tulsa, but from Twitter many of my friends did.

Ah earthquakes how I've missed you.

4.8 prelim centered in Southern Kansas

Lots of students said they felt it here in Norman. I did not.

I'm in class at OU and felt it as well.

We were in OK County courthouse when it happened. judge felt it, but I did not. A witness sitting outside the courtroom said he saw courthouse doors shaking but didn't know what it was.

Well that was a sudden jolt.

You're fast!!

You're fast!!

You've should have seen me jump out of bed as everything jumped. LOL

S. OKC -- felt like 3 sudden waves pushing my bed. Was not a jolt for me.

Yeah it was weird. A quick rough jolt that swung the furniture pretty good and then just a low rumble.

Interesting. I'm wide awake and didn't notice anything at all in NW OKC.

Laying on the couch in the living room doing some work and felt a thud hit the house (east side of Moore). Very quick...almost as if a vehicle had struck it. Definitely one of the more noticeable ones in awhile (for me, at least).

West side Moore. Bunch of us still partying and none of us felt anything

M3.8 - 8km NW of Prague, Oklahoma 2014-11-30 06:59:56 UTC (http://earthquake.usgs.gov/earthquakes/eventpage/usb000t1ca#dyfi)

3.8 NE of Shawnee. The Feel it map tells the store. Mostly Eastern and SE Metro areas felt it...not many anywhere else.

Appears there were two more this morning. I didn't feel them.

I just felt a fairly good one, about 3:44. I also heard a cracking type of sound.

Turned out to just be a 2.8, but it was in my backyard. Actually, approximately one mile due East of my house.

This chart shows how dramatically the number of earthquakes skyrocketed in 2014. Who knows what they will be like in 2015? On the short term side, for the last week, the frequency of earthquakes declined after being well up there. To soon to call it a definite trend, though.

That's just silly cause we just had one about 20 minutes ago.

Yes, I was getting ready to paste that ;-)

We need a 2015 thread. I elect you Bunty.

Just out of curiosity, will the new parking garages on the Preftakes block be built to withstand 5.0+ quakes? What are the current buildings in OKC designed to handle without structural damage?

Here is the 2015 thread, so for the delay...

Just out of curiosity, will the new parking garages on the Preftakes block be built to withstand 5.0+ quakes? What are the current buildings in OKC designed to handle without structural damage?

I don't recall hearing anything about parking garages in OKC having any problems after the 5.6 quake we had in 2011.

With some help from Texas, the earthquake lull is over with. Perry, Guthrie, Edmond and Langston areas continue to be the hottest areas with northwest Oklahoma not far behind.

So I am frustrated at the message OGS puts out there compared to USGS. If you go to the USGS website, you'll see buried on it somewhere is a discussion that they have had proof since the 1970s that waste water injection sites can cause seismic activity. You can also find articles that state they haven proven beyond reasonable doubt that Oklahoma's largest earthquake ever was directly caused by an injection well that was operating too close to a fault line.

Every time I see the same dude trotted out by OGS to talk to the media, he talks in terms of this quake being hard to link to that injection site. I get that, and I know what he's saying, but I find what he's saying misleading. Maybe he has said it, and I haven't heard it, but I don't recall hearing any acknowledgement from OGS that these waste sites can cause seismic activity. We are well beyond some theoretical science here. We know these wells can cause tremors. It would be nice to hear OGS acknowledge that. I feel like they're ignoring that very significant data point by constantly shifting the discussion to "well, I don't know about this specific well and it's correlation to that specific quake...." It smacks of half-truths.

That's something I said last year. Here are some interesting articles just published on the same subject:

At 10:24 pm I felt a strong shock at NW 122 and Council. TV reports it as a 4.0...

It must have been very localized. I live in NW OKC and didn't notice anything.

It must have been very localized. I live in NW OKC and didn't notice anything.

I live in NW OKC and it was very noticeable!

I was dozing and it woke me up in time to hear a loud "BANG!" followed by a very low diminishing rumble that lasted just a few seconds. My wife said it shook the house but I didn't feel the movement, although that must have been what awakened me.

It had a pretty sudden shaking/noise bit at first, and then a long, lighter rumbling vibration that went on for a few seconds. Felt longer than the other ones we've had for the last few years.

At 11:02 we felt a weaker aftershock; OGS lists it at 3.3 and it rattled glass sliding doors in some display cabinets. Location was approximately the same. USGS shows the first one being 10 km down and the second only 5.

Got a long very noticeable rumble in Edmond by the Sam's Club. No jolt though.

I live just south of Mercy hospital and felt both the really strong jolt at around 10:30 and the weaker aftershock around 20-30 minutes later. I was asleep at the time, and that first jolt was so strong it almost felt like something hit the house.

178th & Western area. Just a large jolt and rumble tapering off. No rumble leading up to it. lasted maybe 3-4 seconds total.
