The Balcones Fault Zone divides the Lone Star State in half, loosely following the route of Interstate 35 and passing under Fort Worth, Waco, Austin, and San Antonio. And it’s not just a huge amount of human populations that sit on top of it. There are also thousands of fracking wells boring down in to the earth’s crust, pumping millions of gallons of water down with the direct intent of breaking apart what lay beneath.
Irving itself has more than 2,000 of these sites nearby, and some of the more than 216,000 state wide “injection wells” responsible for disposing of fracking’s wastewater byproduct are in close proximity. Located thousands of feet below the ground, these wells hold millions of gallons of chemically tainted h2o, and science has proven that the pressure and liquid combination can combine to “lubricate” fault lines. And that may well be what is happening in the Barnett Shale region around, yes, Dallas and Irving.
Barnett Shale is the largest land-based gas field in Texas, with an estimated 40 trillion cubic feet of natural gas just waiting to be hammered out of the ground and into your SUV’s tank. It’s a nearly bottomless potential bank account for corporations with the resources to drill and grind. But, as the people of Irving are now discovering, all of this poking and prodding is not without potential consequences.
This is not making the 228,000 residents of Irving, Texas feel very relaxed. The most recent activity had a high point of 3.6 on the Richter Scale. While minor, it’s strong enough to be felt and shake objects. And feel it they did -- the local 911 system was overloaded with calls, the school district held earthquake drills, and the Irving’s mayor met with her counterpart in Dallas to discuss emergency management plans, according to the Dallas Morning News.
And “minor” can be relative.
"Was looking to see if an 18-wheeler wrecked into our building! That is what it felt like,” Irving local Aletha Allie Pate Martinez told a local ABC affiliate.
As of now, there’s no 100-percent definitive scientific connection between this latest swarm of earthquakes and fracking activity, but the United States Geologic Survey noted in a statement on the swarm, “Activities that have induced felt earthquakes in some geologic environments have included impoundment of water behind dams, injection of fluid into the earth's crust, extraction of fluid or gas, and removal of rock in mining or quarrying operations.”
Worth noting: This cluster of quakes is taking place almost directly beneath the Exxon-Mobile world headquarters, which is located in Irving. The company’s CEO, Rex Tillerson, joined a lawsuit last year to prevent a water tower used in the fracking process from being built near his 83-acre horse ranch in a swanky suburban Dallas enclave. Whether these are considered ironic or karmic quakes – that’s up to you. But for the repeatedly shaken up people of North Texas, it’s not very funny anymore.
