RECENT SPIKE IN OKLAHOMA QUAKES

Since October 2013, seismologists have documented a nearly 50 percent spike in earthquake activity in Oklahoma, significantly increasing the chance for a damaging tremor to occur.

A recent U.S. Geological Survey and Oklahoma Geological Survey analysis has revealed that 145 earthquakes of magnitude 3.0 or greater occurred in Oklahoma between January and May 2, 2014, replacing the previous annual record of 109 earthquakes set back in 2013.

The spike in activity is especially alarming when compared to the 1978-2008 average earthquake rate of only two magnitude 3.0 or larger earthquakes per year.

“While it’s been known for decades that Oklahoma is 'earthquake country' we hope that this new advisory of increased hazard will become a crucial consideration in earthquake preparedness for residents, schools and businesses in the area,” said Dr. Bill Leith, Senior Science Advisor for Earthquakes and Geologic Hazards at USGS, in a statement. “Building owners and government officials should have a special concern for older, unreinforced brick structures, which are vulnerable to serious damage during sufficient shaking.”

Fracking could be behind recent spike in Oklahoma earthquakes

There's no proof this was caused by fracking. There have been earthquakes since before humans existed. Human activity can't affect the planet.

Must have been the first earthquake ever in that area. Everyone should be afraid.

Hither and yon
3.5 klicks below surface is way deeper than I've ever heard for an O&G well
Very minor earthquakes occur all the time as a result of O&G operations.
These very minor quakes are almost always caused by disposal wells where unwanted brine and salt water is pumped back down old well bores.
If you get rammy and pump too much brine for too long at too high a pressure eventually you get little shifts and pops in the nderground formations.
It's almost always minor.
As to depth of well bores 3.5 klicks is nothing.
Gas is usually found at much deeper depths than oil.
I have been on several projects involving producing oil wells in excess of 7.5 kilometers depth.
I beleive the Americans have some gas production in the deepwater gulf at around 10.5 klicks
