Oklahoma Earthquakes & Fracking. Are They Related?

Oklahoma Earthquakes & Fracking. Are They Related?

Oklahoma has now surpassed California in the number of earthquakes felt this year!

Is the steep increase in Oklahoma earthquakes related to fracking? Or is it merely a coincidence?

Here’s what makes all this seismic activity a bit suspicious: From two to six normally recorded per year during 1972-2008 and in 2010, 1,047 tremors were recorded with 103 powerful enough to be felt.

Oklahoma was ranked 17th in earthquake frequency in 2003, but now, the magnitude 3.0 or stronger quakes they used to experience only twice per year have hit over 253 times already in 2014, more than once per day. Geologists are warning that a big one (bigger than the 5.6 quake in 2011) is on the way.

The debate about whether all these Oklahoma earthquakes have anything to do with fracking isn’t new. National Geographic’s Joe Eaton wrote this back in March of 2013:

Advanced methods of oil and gas drilling create massive amounts of toxic wastewater. For example, hydraulic fracturing, also known as fracking, uses high-pressure water to unlock natural gas from shale formations. Drillers also use water to force oil from wells that cannot be captured through traditional methods, part of a practice known as enhanced oil recovery.

The use of such methods has exploded in the United States in recent years, contributing to the domestic boom in shale gas and oil production. Much of the wastewater that emerges as a byproduct is pumped into wells beneath the earths surface for disposal.

Although the controversial practice of fracking has been directly linked to at least two seismic events (small tremors in Garvin County, Oklahoma and Lancashire, England), the wastewater injection that follows fracking is much more likely to set the earth shaking. Thats because injection wells receive far more water than fracking sites, said Katie Keranen, lead author of the Geology study. And unlike at fracking sites, the water is not removed. As pressure builds in these disposal wells, it pushes up against geological faults, sometimes causing them to rupture, setting off an earthquake.

There are more than 10,000 oil and gas wastewater injection wells in Oklahoma, which combined force more than 1 billion barrels of toxic waste into the ground per year.

In this weeks Green Divas myEARTH360 Report, we pondered this somewhat freaky uptick in quakes. Oklahoma is known for its tornado alley location, not its fault lines. Listen here…

What about earthquakes in other fracking states?

The number of earthquakes and amount of fracking has grown in the U.S. and researchers are connecting the two events. There were more than 100 recorded quakes of magnitude 3.0 or stronger each year between 2010 and 2013, compared to an average of 21 per year over the preceding three decades. Fracking states like Kansas and Ohio (and Oklahoma), where seismic activity had been infrequent, have seen a sudden increase. Hmmmm…

thanks

Thanks for the article.......not that the frackers would ever admit it.....

That's like asking "Is a Bear Catholic?" or "Does the Pope crap in the woods?"

You bam detcha

Yes I believe they are related

Unless it's against their own profit or agenda, who in the world wouldn't connect the fracking to the added seismic activity?!!!

What about 2 + 2 = 4 does the US govt not get? But I guess when the dirty energy industry is buying off the politicians it's easy to forget how to think rationally anymore. God, what a mess. We're creating earthquakes, poisoning the water and now they want to ship gas overseas so they can cause even more global warming. Future generations, if there are any, will wonder why we're so damn stupid and greedy.

Excellent article. Food additives are also very harmful. After much research and badgering my doct…
