A team of researchers at SMU and the University of Texas has published a paper that concludes there's a plausible link between North Texas earthquakes and Barnett Shale injection wells, the high-pressure wells used to get rid of millions of gallons of wastewater produced by natural gas wells.

Caveats, according to SMU researcher Brian Stump: The team believes there's a correlation between the earthquakes at DFW Airport and injection wells because the airport quakes seemed to be localized around an injection well at the airport. And the quakes stopped when the well was shut down.

But there's no evidence linking actual well-drilling or hydraulic fracturing to the quakes.
