USGS Suggests Connection Between Seismic Activity and Fracking
First time accepted submitter samazon writes "According to a recently proposed abstract by the United States Geological Survey, hydraulic fracturing, or more specifically the disposal of fracking wastewater, may be directly correlated to the increase in seismic activity in the midwest. Results of the paper will be presented on April 18th, but the language of the abstract seems to imply that there is a connection. After years of controversy regarding hydrofracking including ground water contamination and disclosure of chemical solutions, the results of the study, if conclusive, could influence the cost of natural gas due to increased regulations on wastewater disposal." The actual language of the abstract leaves a fair amount of wiggle room: "While the seismicity rate changes described here are almost certainly manmade, it remains to be determined how they are related to either changes in extraction methodologies or the rate of oil and gas production."

We should stop burning oil just in case carbon emissions really are causing global warming

That there was a big bang we should switch of the LHC

That humans can survive in space we should stay here on this rock
Humans have believed a great many things that have turned out to be complete bunk. In the early days of the railways people were convinced that people would suffocate above 20 mph. Cars were deemed so dangerous that a man with a flag had to walk in front of them, because there was no " 100% conclusive evidence" that their suggestions could be proved on way or another
You on the other hand have provided /. with "100% conclusive evidence" that you're not nearly as clever as you'd like to think you are
As opposed to what - the problem is solved, so let's decrease funding? The science is settled, so let's not study this anymore?
I swear, some people sound like they think everything should be funded via unicorn farts and rainbows. Yes, research costs money. Pay up, or end up in the dark ages. Of course, if that does happen, you'll find someone or something else to blame but your own shortsighted smugness that automatically equates every human endeavor with your own base motivation: more money.
Insightful my ass.
Those who can, do. Those who can't, sue.
Don't be silly. Fracture the crust? Are you insane? We can't drill that deep. The Crust is 50 MILES thick. We've NEVER directly sampled the mantle because it's not possible to drill that deep with current technology. We can't even drill 1/4 of the crust thickness. Maximum drilling depth is on the order of 5 miles or 1/10 the approximate crust thickness.
These are minor quakes, they are settlement and movement of sediment layers, not fault shifts. They happen anytime you drill at depth and push or pull material from the drill hole. They aren't anything to worry about, they've been happening for as long as we've been drilling (more than 100 years). I swear you east coasters feel a little shake and freak out.
