2014 Oklahoma Earthquake Discussion

[NoOkie]

I'm pretty sure that was an earthquake just now... Anyone else feel it?

Yeah, was just about to fall asleep when it popped me out of it.

Yep.....
Pretty good shake too.

aftershock just now

[ljbab728]

Didn't feel a thing in NW OKC.

Primary quake was a 4.2 so far. Yes there was an aftershock (see image at the very top of this page).

M4.2 - 11km SSW of Guthrie, Oklahoma 2014-02-17 04:54:59 UTC

4.2, Guthrie.

[KayneMo]

I didn't feel it in Norman.

[Dustin]

I heard it way before I felt it. It sounded like a distant train or a semi engine about 4-5 seconds before the ground shook.

I didn't feel it in Norman.

I was just telling the other half the same. Normally anything north of 4.0 and we tend to feel something down here. Nothing this time in SE Norman.

Tonight's quake is the third 4.0+ quake in 8 days.

I thought at first a semi was coming through the wall, then realized it was another Q.

[venture]

Looks like 2 more small aftershocks.

UPDATE: Three earthquakes recorded near Guthrie on Sunday night | News OK

It's been downgraded to 3.8.

Yep; near NW 122 and Council. One sharp shock as if a truck had run into the house, but that was all...

[bradh]

I find it fascinating how some people feel every little thing, and others not a peep. I'm not far from you Jim and I felt or heard nothing last night.

That Liberty Lake area is active

[Jim Kyle]

My wife didn't feel it either; it was a single sharp shock, and could just as easily been a strong gust of wind blowing on the house. However I did note down the time, just in case.

That's the first one I've felt since the "big" one a couple of years back, and only the third in Oklahoma in my lifetime (the first being the El Remo quake in the early 50s).

M2.6 - 20km SSW of McCord, Oklahoma 2014-02-18 07:15:33 UTC
We couldn't go 24 hours. We just had a small earthquake a few minutes ago.

[SoonerDave]

More shakeums this morning:

M3.8 - 11km SSW of Guthrie, Oklahoma 2014-02-17 04:54:59 UTC

And perhaps a smaller one just a few minutes after?

I wish I could decide whether these smaller earthquakes are a pressure-relief that helps mitigate the risk for a larger tremor, or if they are really just precursors to another big one down the road?

Monthly figures are updated in the chart at the top. We are now averaging over 14 quakes per day in Oklahoma.

Not sure what 24 hour period you are talking about? LOL Monday had one of our highest daily totals I've seen in awhile - 54 total quakes.

We would think this would help mitigate the risk, but then what if this slipping of the faults just makes the situation worse for a large one down the road. Who knows. The 5.6 last time was surrounded by a few 4.0+ quakes, so those didn't mitigate keeping it from happening. Also the significant jump in the number is pretty impressive. 54 quakes yesterday alone. The vast majority (except maybe 5 from my count) where in the same area of Logan County. That area of the fault is really grumpy right now and a ton of pressure in that area.

“We have no way to predict the future. Earthquakes aren’t predictable. Certainly the more earthquakes we have, the more likely we are to have a larger one,” Holland said.

Spend $49 on one of those earthquake sensors. Maybe that will make the earthquakes stop.

Fracking's Latest Scandal? Earthquake Swarms | Mother Jones

"The Wilzetta was a dead fault that nobody ever worried about." Then the drillers came. And so did a swarm of quakes.

[Plutonic Panda]

I believe a new instrument to record earthquakes has been placed in Guthrie.

The impact of fossil fuels is no secret, but until now the short list of dirty energy's villains never included water.

Gee, that article isn't biased at all. /sarcasm.
