New Fracking study in Texas

Not sure if this article has been posted here yet or not...

Seems like this data should make its way to NC's fracking commission:

In a study he recently published in the journal Proceedings of the National Academy of Sciences, Frohlich analyzed 67 earthquakes recorded between November 2009 and September 2011 in a 43.5-mile (70 kilometers) grid covering northern Texas' Barnett Shale formation. He found that all 24 of the earthquakes with the most reliably located epicenters originated within 2 miles (3.2 km) of one or more injection wells for wastewater disposal.

 

Here's the Texas fracking study itself

From the article emphasis mine:

...researchers have long known that fluid-injection operations can trigger earthquakes. For instance, in 2006 one geothermal energy site triggered four earthquakes in Basel, Switzerland, ranging from 3.1 to 3.4 on the Richter scale. Fracking also appears linked with Oklahoma's strongest recorded quake in 2011, as well as a spate of more than 180 minor tremors in Texas between Oct. 30, 2008, and May 31, 2009.

 

I haven't really covered earthquakes

much, but any geologist will tell you that introducing a lubricant into rock formations is likely to produce movement of some sort.

And a big part of the danger in doing that isn't the quake itself (most are micro), it's the potential release of high concentrations of previously sequestered deposits of naturally-occurring toxins and radioactive elements. Stuff like that can go from barely-noticeable levels to lethal concentrations pretty quickly.
