Looks like total quake reports for Oklahoma per the OGS catalog for 2013 had us with 2,808 measured quakes.

Mag 4.0 or higher: 3 ( 4/16 4.4 & 4.2 and 12/7 of 4.8)
Mag 3.0 to 3.9: 105
Mag 2.0 to 2.9: 952
Under 2.0: 1748

So playing with the numbers that is over 7 quakes per day. Around two magnitude 3.0 or higher quakes per week. Welcome to the new normal. :)

Only California and Alaska have been more lively for earthquakes.

The "new normal" is taking some adjustment for THIS nearly lifelong Oklahoma resident. I actually caught myself in the theater the other night wondering if the shaking in my seat was an earthquake, completely overlooking the oversized foot from the lunkhead sitting behind me using the back of my seat as a footrest..... :)

Only California and Alaska have been more lively for earthquakes.

And I mean of all the states, not to include world wide.

Well according to the OGS site, so far we are pushing around 10 quakes per day so far. Nothing has been added for today yet, and just a couple that were over 3.0 so far so the rest likely weren't felt.

Ho hum, it was kind of a quiet day today with only three ranging from 3.2 to 3.7.

Yeah...unfortunately it doesn't catch all of them that the OGS gets, but their site hasn't updated since the 2nd.

Wasn't sure which thread to add this to, since it bridges both weather and earthquakes, but it didn't seem to merit its own thread... so I'll post here...

Okay, just got a very unsettled call from my mom in S. OKC who swears she just sat through an earthquake - even heard some wall hangings rumble. Haven't seen or heard a thing about it anywhere. Anyone?

Haven't seen anything for this afternoon come across. One very weak one (2.1) this morning around 5AM and that is it.

Also the list is updated in the article now as the OGS started updating again.

Earthquake tally updated. No quakes added to the catalog for today yet. For the first ten days of January we are at 94, or 9.4 per day which is above our 2013 average.

Whenever I feel an earthquake in SW OKC (which is next to never), I always wonder if it is just a big one on the east side of town, or the outer edge of a huge one on the New Madrid fault. When we had that big one a couple of years ago, the house just shimmered from north to south - so weird. I turned on the news expecting Missouri to have dropped into a hole.

Earthquake tally is updated. Interesting to note, we've gone 11 days now with a 3.0 or higher magnitude quake. We averaged 2 per week last year, so it could be argued we are behind now.

I think I felt and heard a brief earthquake in Stillwater at 12:50pm. My guess around 3.0 M, or less.

All the fracking must have stopped! ;)

Hmmm..either the pressures that were causing them last year have substantially been released for now, or the absence of such pressure releases is actually leading up to a whopper down the road...

Looks like we have been mostly quiet now for 2 days straight. No reported quakes of any magnitude from OGS. Now the question is, which scenario is it. :) I'm more on the side of things building up to a 4.0+ again or several 3.0+ in rapid order to deal with the pressure building up. It would be nice if things were getting quieter now, but I just don't see how such an active swarm would just go quiet so quickly.

Keep in mind, the industry will frack less according to how much cold weather, at least that's what i've read. Now if fracking is related to the earthquakes, I have no idea...?

I think I felt and heard a brief earthquake in Stillwater at 12:50pm. My guess around 3.0 M, or less.

The earthquake I experienced turned up as recorded plus another one later that morning shortly before noon. I also felt that one. They were under 3.0 and centered just several miles from Stillwater. I'm glad the ones below 3.0 can barely be felt and probably more impressive for the brief not very far distant thunder like noise that make.

Nice earthquake just now in North Edmond

Nothing has registered on my MyQuake app but I'm sure it will soon enough.

Nothing has registered on my MyQuake app but I'm sure it will soon enough.Do you live in Edmond? If you did, I don't know how you couldn't feel it, although some people didn't feel that huge one a year ago lol... this one was the biggest I've felt since that one back in a few months ago.

The Friday quake near Edmond registered 2.3, certainly no stronger than either one of the two quakes near Stillwater earlier in the week.

Nope, I live in NW OKC. There were a couple the other day up around Stillwater. But I know what you mean, I felt one in Edmond one night that didn't register and it was a nice lil sway.

Looks like a decent quake around 11:33 this evening based on the Tulsa seismogram.

Interesting. I thought maybe I felt or heard something but decided I was just being too sensitive.

Another quake in the Stillwater area occurring at 7:01 PM, Friday, registering 2.6. It was not as close by as the previous two, being 3 mi. south of Perkins. I didn't notice that one, probably from it being further away and was watching TV at the time.

Unless that brief thumping noise was caused by something else, the Stillwater area has just had another quake around 12:55 am Sunday. The noise was more noticeable than the shake, so if a quake, it was probably under 3.0M.

Not sure about 12:55...but at 12:38 there was a 3.2 down east of Holdenville. Nothing else was picked up on the seismographs that are online.

Ho hum, just another 3.4.

I didn't feel it even though it was slightly stronger than recent ones. Interesting how the Enid earthquakes have definitely subsided, while the Stillwater area ones persist. There's definitely oil drilling in that area. Surely new wells have started to produce. If someone want to blame the quakes on that, I wouldn't be surprised.

Strongest quake of the year so far has occurred about 15 minutes ago or so. Looks like a 3.9 so far near Stillwater.

Is that the same thing reported here much later?

Looks like 3 quakes showing up on the seismograph for today so far. Strongest is a 3.9 up in Southern KS.

Earthquake totals updated. Ended January with 7.5 quakes per day on average, which is pretty much the same as last year.

Just had a short but strong one, north and east of Edmond.

wifeypoo said she felt one but I of course was totally oblivious

4.4 Epicenter 8 miles East of Guthrie on Hwy 105 & Henney Rd.

4.4 according to the above website.

Epi was 4 or 5 miles from my house. BAM!

That must have shook things up!

4.1M for the new strongest quake of the year. Lots of people felt it in Stillwater and especially Guthrie, but didn't seem real impressive to me.

Just had a short but strong one, north and east of Edmond.

Haven't seen the local news since Friday, but I knew I felt one...it was a "roller."

I've updated the tally in the article. We are well above "average" right now for quake activity for the month. I added a new row for "Avg Per Day" to add more perspective to the numbers. I'll add some additional date to compare previous years by.

For yesterday's quake, it was officially pegged in as a 4.1, down from the original 4.4 measurement. It is interesting to note just how hit and miss the "Felt It" map is with this one since usually when we go above 4.0 things start to get more widespread in reports.

I put together a quick chart showing the earthquake numbers for the last 15 years (including this year so far). The numbers prior to 2010 unfortunately dwarf the previous 10 years so much that it is hard to pick up on them at all. No disputing on just how significant 2013 was in the volume of quakes that occurred in the state. While it can be hard to argue we are going to keep seeing increasing numbers, the basic 5 year trend is definitely there. The white dotted line is the daily average of quakes recorded.

Venture...I am having a bit of a brain fart here. What do the numbers on the right side represent?

Sorry, I forgot to label it. Those are average quakes per day.

They obviously weren't officially submitted but I had a couple of friends in Owasso and Tulsa that said they felt it before there were any media reports.

3.8 Quake about an hour ago now just north of Chandler.

An outsider's perspective upon Oklahoma's recent earthquake activity and elsewhere in the world.

There has been just as much fracking in western Oklahoma, with zero earthquakes. If fracking is causing it, it's due to the fact of where the fault lines lie.

Hope this makes sense.

I think it is safe to say we really don't know the exact reason why we've become of the top seismically active states in the nation. We can list all the various theories, but no one here and definitely not those with a special interest for/against oil and natural gas will be able to provide an answer or correct test those theories.

I hope the earthquake intensities don't increase to keep pressure contained on the oil companies as the source for blame. Their current level of intensity and their centering in rural areas isn't too hard to tolerate, if caused by oil field operations. If they take a turn for the worse and cause deaths and injury, then, I imagine it would be highly prudent for the governor to demand a moratorium on oil and gas drilling to be put into place in the region where the quakes are coming from, especially if geologic experts suggest it.

Not sure there is any real connection, but maybe the party's out near Sparks are getting a bit rowdier?

An interesting article from about a year ago: Wastewater Injection Spurred Biggest Earthquake Yet, Says Study - The Earth Institute - Columbia University (http://www.earth.columbia.edu/articles/view/3072)

This kind of backs up what I was trying to say.... the salt water disposal wells may be causing it, it just has to have a fault nearby to create the quake. The article also says they've been doing the wastewater injustions for 17 years in the area without incidence.

So is it fracking or saltwater injection that's the root of the cause, or maybe both?

or a completely natural increase in seismic activity... i mean after all, Oklahoma has a long history of seismic activity. We just have only been keeping records of it for a fairly short amount of time

A whole lot of special interest going on in this thread....

Fracing waste water Wells from Oklahoma, Ohio, Pennsylvania, and dozens of other places with almost no recorded seismic activity until the last..o seven years....that have 1 thing in common.

Nothing to see here move along.

This whole fake industry discussion reminds me of the 25 years it took to kinda sorta say that cigarettes may have something to slightly due with cancer.
