How Fracking Causes Earthquakes, the Animated GIF

 

Contributing writer Michael Behar has an intriguing feature today that details the science behind the link between injection wells and earthquakes. For a visual rundown of the fascinating process, check out the GIF below.

Drillers inject high-pressure fluids into a hydraulic fracturing well, making slight fissures in the shale that release natural gas. The resulting briny wastewater flows back up to the surface, where it is transported by truck or pipeline to nearby injection wells. The liquid is then pumped down the injection wells to a layer of deep, porous rock, often sandstone. Once there, it can flow in every direction, including into and around faults. Added pressure and lubrication can cause normally stable faults to slip, unleashing earthquakes.

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.
