It registered 3.1, three miles ssw of Stillwater. The one this morning was 2.9.That means it was almost twice as strong; since it's a log scale, a difference of 0.3 would be twice as strong, and a difference of 1.0 would be 10 times stronger....

Saturday's three quakes felt in Stillwater were centered in the countryside just outside town:

8:06am -2.9- Prairie Rd between Richmond and Lakeview
9:11pm -3.1- 44th between Western and Washington
10:45pm -3.0- 44th between Brush Creek and Fairgrounds

OUR VIEW: State needs quake task force » Opinion » Stillwater NewsPress (http://www.stwnewspress.com/opinion/x2039931993/OUR-VIEW-State-needs-quake-task-force)

Unlike in Kansas, it may not be regarded as politically feasible to create something like a quake task force in Oklahoma. Anyway, surely the Oklahoma Geological Survey has already been doing something in that regard. It recently added a seismologist. And what does it say: http://newsok.com/oklahoma-geological-survey-is-shaking-things-up-amid-rash-of-quakes/article/3934987

Another earthquake happened at Stillwater at about 6:11pm. The Wichita Mtns. seismograph clearly picked it up. There's been around 5 others elsewhere for Sunday.

EDIT:
It was 3.1M, 10 miles southwest of Glencoe.

At some point it'll be realized this is the new normal and we won't be seeing headlines in the paper every day after a 3 pointer happens. They are just too common anymore to really be news worthy.

I've updated the table and it includes this latest quake this evening. Our daily averages continue to increase.

That looks familiar... just a few posts above (#102)...

:tongue:

My bad!

Another one this AM, in the Spencer area...

Although I guess, as Venture pointed out, 3.0's are the new normal, so I guess these aren't quite that big a deal anymore..

..Unless you're the one whose Post Toasties got sloshed out of its bowl :)

LOL...of course if they are right on top of the epicenter I think even a high 2 pointer would be news to that person. :)

So far, Tuesday has been quiet.

Earthquakes jolt Stillwater; OSU will join study » Local News » Stillwater NewsPress (http://www.stwnewspress.com/local/x2118240570/Earthquakes-jolt-Stillwater-OSU-will-join-study)

Over the weekend, one of our old family farms had 3 quakes hit on it within 24 hours, section 17-18N-1W. This is about 5 miles southeast of Mulhall. They were from 3.5 to 2.5 magnitude.

Ho hum, only 3 on Wednesday.

Three earthquakes shake northern Oklahoma | News OK (http://newsok.com/three-earthquakes-shake-northern-oklahoma/article/3937560)

An employee of mine lives in Guthrie and also has a side job maintaining a number of rental houses in and around Guthrie. He's had one under-slab water line break in his house and two others in rental units in the last week. Coincidence or earthquake damage? Who knows?

Friday happened to turn out to be Earthquake Freedom Day in Oklahoma. No earthquakes of 2.0M or above happened that day. But they resumed to at least 3 above 2.0 on Saturday, and so far, 6 for Sunday. I just heard one of them boom in the distance, while barely feeling a shake. It registered 2.6M, 6 mi. east northeast of Stillwater at 7:54PM. The strongest one for Sunday has been 3.2, south of Ponca City.

Citizens take their concerns about the earthquakes to the wrong government body:

County residents seek drilling moratorium » Local News » Stillwater NewsPress (http://www.stwnewspress.com/local/x1783700968/County-residents-seek-drilling-moratorium)

With a scary way to end the story, “You don’t know what’s happening underground.”

At 7:53 pm another earthquake happened near Stillwater with the brief sound of distant thunder and little shake. No wonder. OGS page indicates it registered 2.4M, centered ENE of Stillwater, one of the state's most active areas. It seems lately these earthquakes have had a tendency of more often staying under 3.0.

In addition, kust noticed the OGS page indicates another earthquake happened only about 10 minutes later, centered near the same spot as the above one. I don't recall sensing that one. No wonder. It was weaker, registering only 2.1M.

Earthquake table updated. Very active February and March is already starting out in similar fashion.

The epicenter of the 3.6 earthquake this morning at about 8:19 was less than two miles from my home. The house rattled pretty good/bad for a couple of seconds. Then we felt another one at 9:49 but it wasn't as strong. It hasn't shown up at OGS yet.

Not Oklahoma but...6.9 quake off northern California coast.

Maybe Whale migration. Pooting off coast. The Gray's should be heading north with their babies.

Earthquake list has been updated. March is averaging under February now, but for the year we ticked up slightly.

Oil companies are also being blamed by rural residents for being behind fires getting started. Interestingly enough, the area in the article referred to, North West Point Rd., is not real far from where recent earthquakes have centered east of Stillwater.

3 today in OK and 2 in southern Kansas?
9 since yesterday morning.

Pretty crazy...

The game caller called the earthquake, but apparently a lot of other people didn't for this 2.8 earthquake. The way the camera shook for such a weak quake, though, it makes me wonder if it was real. Oh, well, if telephoto was used, wouldn't it exaggerate a minor shake? With no sound like thunder heard, it makes me further wonder.

I'm going to go out on a limb and guess that camera was sitting in deep center-field, and hence was zoomed waay the heck into get that (relatively) tight shot of the pitcher-batter's box setup. Anytime you zoom that much, even the slightest vibration can be drastically exaggerated. Maybe they need to start using steadicams for baseball videos in Stillwater LOL

Yeah...a slight gust of wind could have done that as well.

Looks like there were about 5 foreshocks during the hour before the larger quake.

I can't decide if these multiple smaller tremors are a pressure release that will prevent a bigger one later, or are a precursor to a bigger one later LOL :)

pretty good shake up in east Edmond just now

There certainly was one in Stillwater at 6:16 pm on Friday. It was 3.2M, centered 6 mi. NE of Stillwater. It sounded more like distant thunder than an explosive noise. It lasted for about a second. I barely felt it, but made my house go creak, like it does from a high wind gust.

So evidently there was a quake in Choctaw about an hour or two ago. I usually feel them, but my home was quiet this time.

It was a 3.7.

Additional weekend quakes have ranged up to 4.3M near Crescent as of early Sunday morning.

@KOCOBrad: I'm concerned that these quakes getting stronger near Crescent are foreshocks to something larger today. Review earthquake safety.

Okay. What's up with this? Got that off twitter.

Whatever, his comment reflects that weekend quakes now top out at 4.4M near Crescent as of late Sunday morning. Thank goodness, this cluster of quakes aren't centered near a larger town.

Most of these aren't doing anything more than rattling a few pictures on the wall. It is interesting to see that the 4.4 wasn't really felt over a wide area as usually is the case for most 4.0 or higher quakes.

The table at the top has been updated. March has been slower than February - but still a day to go. :)

I think Brad needs to stick to meterology.

It's been slightly upgraded to 4.5.

Stillwater had a baby earthquake, 2.3, 1 mile east of town at 4:43 pm today, 3/31. But it was enough to hear distant thunder and make my house give off a small creaking noise. Three others elsewhere. Recent Oklahoma Earthquakes (http://stillwaterweather.com/okareaearthquakes.php)

OOPS, another quake just happened at 5:35pm. It was more startling. I bet it went over 3.0.

UPDATE: Nope, not a 3.0+. OGS puts it at 2.6 at two miles SSE. Anyway, those baby quakes definitely make an impression when they're almost centered under you.

Two late Monday afternoon quakes pinpointed in the Stillwater area on 3/31/14. The weaker one was within the city limits east of the cemetery. (Another one happened in about the same location earlier this year.) The stronger one happened almost in city limits. That quake happens to be not far from where successful oil drilling has been going on for about the past year. I don't know if it's associated with waste water injection wells.

4.2 in Crescent

USGS Reports 4.2 Earthquake Near Crescent - News9.com - Oklahoma City, OK - News, Weather, Video and Sports | (http://www.news9.com/story/25170466/usgs-reports-42-earthquake-near-crescent)

Congrats - Oklahoma earthquakes made the Drudge Headline.

DRUDGE REPORT 2014® (http://www.drudgereport.com/)


Oklahoma recorded 278 earthquakes from 2008 through 2013 that have registered on the Richter scale at a magnitude of 3.0 or greater, a level that can shake objects inside a home.

Before that, from 1975-2008, the state on average recorded less than six earthquakes a year.

That's pretty crazy. There are a few reasons that could be, fracking could be one of them, but I'm still not convinced.

And one of the reasons is "earthquakes happen". LOL

And one of the reasons is "earthquakes happen". LOLyeah, that to. ;)

Here are some reassuring words from a Tulsa geologist when questioned soon after the 2011, 5.6 quake. I hope he still feels the same way:

Dr. Bryan Tapp is a structural geologist at the University of Tulsa; basically he studies how rocks move beneath the earth's crust. He says Oklahoma has small earthquakes every day.

"We are still under a region that is trying to shift, but it is relatively slow," said Dr. Bryan Tapp, Ph.D.

Dr. Tapp says you can blame this on events that first happened 300 million years ago. He says when the Wichita, Arbuckle, and Ouachita Mountains were formed, the ground rose up. But just north of the Wichita and Ouachita Mountains the ground sunk and formed the Anadarko and Arkoma basins.

This action caused a fault line to form between the two basins, that fault line is where the epicenter to these large earthquakes is located. He says the earth is still trying to relieve pressure from those long ago geologic events.

"So we just seem to be relaxing, just slightly, over time," he said.

One thing he's positive of: this mess was not caused by fracking.

"There's no way that this particular fault or this particular earthquake could have been activated by oil field activity; there's just no evidence of that," said Dr. Bryan Tapp, a structural geologist.

Dr. Tapp says we can expect some more earthquakes in the future but probably around the magnitude 3 range.

He would be surprised if we see another over five and is confident that we are not gearing up for the "big one."

Felt it in downtown OKC.

Felt that one in Norman.

shook for a good 5 seconds up here in east edmond

It just popped up on the seismogram image at the top...usually has to be around a 4 or higher for us to feel it down here. We'll see.

Felt it downtown OKC. Wife felt it at 122nd and Lake Hefner Parkway.

In Stillwater, for the one shortly after 11am, my house felt it more than I did. The house made a creaking noise for a second. I hardly sensed any shaking or heard thunder in the distance. The seismogram doesn't seem to look like it was one of those baby, under 3.0 quakes. We'll see.

OGS Earthquakes ‏@OKearthquakes (https://twitter.com/OKearthquakes) 21s (https://twitter.com/OKearthquakes/status/453205775322976256)
Magnitude 4.4 at 2014-04-07 11:03:03.930000 (CDT) 5.1 miles SSW of Coyle; 35.890,-97.273,z=5.2km

This is going to put the quake in the same area as the 4.2 yesterday.

Oh, dang! This one at 11:38 am came with a rather loud distant thundering noise this time. It was certainly more startling than the previous one. I'm glad it only lasted about a second.

So... here's a question... why is the Oklahoma Geological Survey earthquake rating typically significantly higher than the USGS earthquake rating? Is OGS looking for more publicity with better attention-grabbing headlines that the local media then likes to trumpet over the USGS number(s)?
