Biggest Oklahoma Earthquake in Memory Linked to Oil Industry

Wastewater left over from fracking wells eventually ends up deep underground, where it can cause earthquakes. <a href=http://en.wikipedia.org/wiki/File:Horizontal_Drilling_Rig.jpg>Wikipedia</a>

In November 2011, a destructive 5.7-magnitude earthquake rocked the grasslands outside the small town of Prague, Oklahoma. The shaking leveled 14 homes, shut down schools for repairs, and was felt across 17 states. It also troubled seismologists, who’d never expected an event so large to hit an area that was supposed to be seismically safe.

According to the results of a new study published online yesterday in the journal Geology, the temblor was potentially linked to the underground injection of wastewater from local oil operations. In fact, the fault that triggered the event ruptured just about 200 meters from active injection wells. Changes in water volumes deep underground may have reduced the stress on the rock, allowing the fault to slip. 

The underground disposal of wastewater has skyrocketed due to the recent uptick in hydrofracking operations across the country. Other studies have linked wastewater injection wells to earthquakes in otherwise seismically quiet areas of Arkansas, Texas, Ohio, and Colorado. The Oklahoma quake, however, was the most powerful. 

For the current issue of Mother Jones, contributing writer Michael Behar followed Katie Keranen, the lead author of the Geology study, into the fields of the Sooner State for an elegant look at the science behind the link between earthquakes and the oil and fracking industries. Behar also interviewed seismologists and government officials who are increasingly concerned that loose regulations on wastewater injection could cause the next big one in a region unprepared for seismic activity. And he details the shadowy ties between industry and science that may complicate meaningful regulatory change.

SIX TRUTHS

Reclaiming power from those who abuse it often starts with telling the truth. And in "This Is How Authoritarians Get Defeated," MoJo's Monika Bauerlein unpacks six truths to remember during the homestretch of an election where democracy, truth, and decency are on the line.

Truth #1: The chaos is the point.

Truth #2: Team Reality is bigger than it seems.

Truth #3: Facebook owns this.

Truth #4: When we go to work, we're in the fight.

Truth #5: It's about minority rule.

Truth #6: The only thing that can save us is…us.

Please take a moment to see how all these truths add up, because what happens in the weeks and months ahead will reverberate for at least a generation and we better be prepared.

And if you think journalism like Mother Jones'—that calls it like it is, that will never acquiesce to power, that looks where others don't—can help guide us through this historic, high-stakes moment, and you're able to right now, please help us reach our $350,000 goal by October 31 with a donation today. It's all hands on deck for democracy.
