Earthquakes Correlated With Texan Fracking Sites
eldavojohn writes "A recent peer reviewed paper and survey by Cliff Frohlich of the University of Texas' Institute for Geophysics reveals a correlation between an increase in earthquakes and the emergence of fracking sites in the Barnett Shale, Texas. To clarify, it is not the actual act of hydrofracking that induces earthquakes, but more likely the final process of injecting wastewater into the site, according to Oliver Boyd, a USGS seismologist. Boyd said, 'Most, if not all, geophysicists expect induced earthquakes to be more likely from wastewater injection rather than hydrofracking. This is because the wastewater injection tends to occur at greater depth, where earthquakes are more likely to nucleate. I also agree [with Frohlich] that induced earthquakes are likely to persist for some time (months to years) after wastewater injection has ceased.' Frohlich added, 'Faults are everywhere. A lot of them are stuck, but if you pump water in there, it reduces friction and the fault slips a little. I can't prove that that's what happened, but it's a plausible explanation.' In the U.S. alone this correlation has been noted several times."
For a minute there I thought this was a gratuitous shot at The Best Little Whorehouse in Texas.
I'm not defending fracking, per se, isn't it better to have a bunch of small earthquakes than one big one?

Oh please, they could prove beyond a shadow of a doubt that fracking, or some part of its process, causes earthquakes, there won't be the slightest change in procedure. After all, that oil's not going to sell itself sitting in the ground there.
Does money ride on an action being taken? If yes, it's absolutely irrelevant what the effects are of it being done, it's going to be done.
There was a MUCH stronger association between employment and fracking sites.
But causation does require correlation, along with a reasonable basis for the cause. Maybe something like "if you pump water in there, it reduces friction and the fault slips a little."

Yet another believer in the big lie that earthquakes don't cause fracking. :P
I read TFA and all I got was this lousy cookie
Clearly, if we were just allowed to dump wastewater into local rivers and streams, none of these earthquakes would have had to happen. Why are environmentalists objectively pro-earthquake?
When A is correlated with B, there are 3 possibilities. A causes B, B causes A, or both B and A are caused by a third factor C.
So are you claiming that earthquakes cause fracking? Or are you claiming that some unknown third factor causes both earthquakes and fracking? If you don't have any plausible suggestions for either, causation seems like the most likely explanation.
Give me Classic Slashdot or give me death!
The people tagging this story with "correlation is not causation" are a perfect example of what Slate is talking about this week on how silly this meme has become. Ok, so are you saying that the frakking does not cause the earthquakes? What, is it the other way around? No, I'm guessing it's a mythical third factor causing both. Some mystery force is causing both the frakking and the earthquakes. Maybe birds. Who knows? But nothing something correlated!
People, the correlation thing is nice and all, but can we please not forget Occam's rasor? The frakking causing the earthquakes really is the simplest explanation, digging out the correlation argument is just as logical as closing your eyes and singing la-la-la. Proving correlation does not prove causation, but it is a necessary step in doing so, not a logical no-no. Even the scientist quoted in the article is aware of the distinction. There is no "gotcha!" here.
Thank you, Slate. I really had not realized how silly this had become.
When A is correlated with B, there are 3 possibilities. A causes B, B causes A, or both B and A are caused by a third factor C.
Seems like 5 to me.
A causes B
B causes A and B is cyclical (or we're time traveling)
B and A are both caused by C
B is caused by C and A is caused by D, C and D are unrelated
B and A self-contained events with no direct external cause and no relationship to each other
One thing nobody seems to be realizing is that it may very well be ok to decide that this is a risk that's worthwhile.
Occasional small earthquakes vs. massively cheaper natural gas with a thousand year supply and 30% lower emissions than coal? Sign Earth up, peeze.
