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.

[BlackmoreRulz]

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. Logan County jail now has cracks: 4.1-magnitude earthquake shakes Langston | Oklahoma City - OKC - KOCO.com

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.

[Damon Lewis]

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.
