Oklahoma Earthquake Activity

[okie75]

No funny weed, just weird blue sky at sunset. Thought someone may have snapped a picture. My camera only takes magenta pictures, something wrong with it. My tinfoil hat fits fine, I bet they've found ways to penetrate tin foil anyway.....

[Thunder]

Boom! We had another one just before midnight (3.2). Did you feel it?

Is it still a total mystery what's causing all these earthquakes?

Is it still a total mystery what's causing all these earthquakes?

I still maintain oil & gas development is suspect. I don't know for sure, but if there is a giant gas field in the area and then you could imagine what happens when some of the enormous pressures are released. Something is certainly going on.

I know that when the quakes centered around SE 44th and Bryant started, about 3-4 years ago, they were preceeded with renewed activity at the oil and gas wells in the area that had been dormant for close to 20 years. I have a friend who lives in the area who found it a little too coincidental that approx. 2-3 weeks after she started seeing trucks going into these well sites, for the first time in the 15 years she had lived there, that the quakes started. I don't pretend to know much about these things, but it does seem suspect.

The good thing, the USGS and OGS along with others have more equipment in the state now to help find the cause for these. The state is naturally seismically active, but this swarm has been pretty concentrated compared to past years. There was also an issue down in the Dallas area not too long ago where gas drilling and refilling with water caused a swarm of quakes. The operation was halted and the quakes did too.

[mugofbeer]

I could be mistaken but I dont think there is O & G drilling in that area is there? The DFW area certainly does.

Thought this was interesting to read this morning:

Fault lines found under Jones, site of earthquakes

Associated Press - February 16, 2010 8:05 AM ET

JONES, Okla. (AP) - New detectors have found fault lines in the Jones area - where dozens of small earthquakes have been recorded since last year.

Six quake detectors known as NetQuakes accelerometers are on loan from the U.S. Geological Survey. They were set up this year to help scientists find answers to earthquake activity in the region.

There have been nine earthquakes felt this year in the area around Jones after 27 were recorded last year. No serious damage or injuries have been reported.

The NetQuakes machines are at Luther Middle School, Jones and Choctaw high schools, Science Museum Oklahoma and at two private residences in the area.

Makes sense. I'm wondering if this is an offshoot from the Nemaha or Central OK Fault. Kind of interesting that it has taken this long to discover it, but also shows there is a lot more going on underground we don't know about.

There has been conflicting reports. People are reporting 2 quakes, one at 0835 and one at 1012. The first quake was reported a 2.6 and the second (while I was gone) reported a 2.9.

Those are not conflicting reports. They are two separate quakes. The site you are looking at are seismograph recorded events, they don't record "quakes" that only people feel but not the machines.

Another one yesterday, 21st, registered a 2.5 and today registered a 2.1.

Glad you all keep that stuff up around Jones and such. I'm not certain
they have been able to fully shore up the Vista down here in Norman yet.

Wouldn't want to lose it for good.

[SkyWestOKC]

I've never felt one. Might need to take a trip to California, or Jones...hmmm

Just had a 4.4

Felt it in Edmond

[adaniel]

OMG I was hoping I wasn't crazy.

I felt it too very strongly at NW Expressway and Council.

[ksearls]

I felt it at Villa/May area! It made a really loud sound like a big truck driving down the street! Wow, weird day for Mother Earth.

That's exactly what it felt and sounded like to me too here in MWC. I thought it was a truck at first.
