The magnitude 5.6 earthquake that jolted Oklahoma State University’s stadium last night shortly after the Cowboys defeated Kansas State was the state’s strongest earthquake on record, said Jessica Turner, a geophysicist with the U.S. Geological Survey.
“The crowd of nearly 59,000 was still leaving Oklahoma State’s Boone Pickens Stadium when the earthquake hit, and players were in the locker rooms beneath the stands,” says this article on Yahoo.com.
Felt throughout Oklahoma and into Arkansas, Kansas, Missouri, northern Texas and some parts of Illinois and Wisconsin, the temblor was centered near Sparks, 44 miles northeast of Oklahoma City.

I have been reading online where activists are trying to blame hydraulic fracturing for the earthquakes.
It never ends…
I would say, considering the depth, it stands a pretty good chance of being true. I’ve never figured out how fracturing the underlying rock is supposed to be safe for the layers above. Sort of like cracking the foundation of a house and expecting the second floor not to be effected.
I recall as a child in the early 1970′s that one of my teachers described how water had been pumped into the ground, in Colorado I think, and that earthquakes began to occur. I think the water was radioactive wastewater from nuclear facilities which was being pumped deep underground as a means of disposal. Following the earthquakes the practic was stopped and the earthquakes stopped.
I’m all in favor of recovering our fossil fuel resources, but I’m not surprised if fracking is or will cause earthquakes in some locations.
Hey GW! It was in 1962 near Denver, when the Army was disposing of waste water, injecting it into the bedrock around an inactive fault. They soon discovered that the water was ‘lubricating’ the faultline.
Fracking causes earthquakes according to USGS. And here is this article:
http://thinkprogress.org/romm/2011/11/02/360014/shale-fracking-earthquakes/
Does anybody REALLY believe any agency connected with this presidential administration …? Seriously?
the incidence of quakes in area that didnt have em often , if at all, before frakking or disposal of waste via underground means, is getting to be more than co incidental it appears.
see germany? or was it belguim? eu anyway also had issues similar and they canned the drilling, no more quakes..
In the UK, Cuadrilla Resource decided that fracking operations caused earthquakes in a part of the UK with no historic seismic activity. It was actually the injection of waste frack fluids that caused the quakes, rather than the hydraulic fracturing itself. They suggested that the fluids “lubricated” deep fault lines, making them more likely to slip. That report is now entering peer review. Right on the heels of Cuadrilla’s announcement, news is spreading that the United States Geological Survey has released a report (pdf) that links a series of earthquakes in Oklahoma last January to a fracking operation underway there.
For whaat it’s worth, prior to 2010, the state typically had around 50 earthquakes a year. In 2010 more than 1,000 were recorded. In additon, sunspot activity is declining and pole shift is accelerating. Some have wondered if the mass animal deaths in nearby Lousiana and Arkansas that occurred back in 2010 and 2011 could be attributed to magnetic field flux..
I feel the urge to re-read Robert’s “Magnetic reversals”! I THINK that a complete pole reversal can take around 1,000 years, but during that time, multiple poles start to emerge.
The South Atlantic Anomaly is worth a study on this issue:
http://en.wikipedia.org/wiki/South_Atlantic_Anomaly
That is incorrect, the area of the UK in question has had such tremors before. They were fairly routine but never mentioned because of their lack of magnitude 1.5 – 2.4, about the same as a truck going past your house! However because fracking is going on it has been linked to (and jumped upon by the loony greenies) activity in this relatively unstable area.
I find it very interesting that of all the listed quakes in OK, almost all of them are exactly the same depth of 5 miles. Been looking at earthquake clusters on the USGS site for a long while now and this is not the normal pattern. The depth routinely varies but not in this case.
