A spate of earthquakes across the middle of the U.S. is “almost certainly” man-made, and may be caused by wastewater from oil or gas drilling injected into the ground, U.S. government scientists said in a study.
Researchers from the U.S. Geological Survey said that for the three decades until 2000, seismic events in the nation’s midsection averaged 21 a year. They jumped to 50 in 2009, 87 in 2010 and 134 in 2011.

Having finished reading this article I can find nothing in it which says fracking causes earthquakes.
“A naturally-occurring rate change of this magnitude is unprecedented outside of volcanic settings or in the absence of a main shock, of which there were neither in this region,” Ellsworth and his colleagues wrote.
The scientists are pretty sure fraking may be the likely factor. Of course I forgot you are the last bastion of science on ATS and know more then all the geologists and other scientists combined.
We also find that there is no evidence to suggest that hydraulic fracturing itself is the cause of the increased rate of earthquakes. The fact that the disposal (injection) of wastewater produced while extracting resources has the potential to cause earthquakes has long been known. One of the earliest documented case histories with a scientific consensus of wastewater inducing earthquakes, is at the Rocky Mountain Arsenal well, near Denver. There, a large volume of wastewater was injected from 1962-1966, inducing a series of earthquakes (below magnitude 5).

No.
I'm going by what the geologists say. From the original source used in the article.

The earthquakes are caused by the injected material lubricating existing faults, causing them to slip. It only has been seen to happen at a few waste injection sites and it is not restricted to fracking fluid disposal.
Okay. Your source actually makes you sound kind of silly on one hand it says that, injecting fluids into the earth is KNOWN to trigger earthquakes, but somehow fraking which is injecting liquid into the earth, is not proven to cause quakes?

It's not exactly "my" source. It's the source used in the article of the OP and it says that fracking has not been found to cause earthquakes. I was accused of not agreeing with those who have done the studies. Maybe you can bring it up with them. Maybe you can find out how they make the distinction. Maybe you can find out the differences between fracking and waste injection wells. Maybe you can actually read what the original source says.
