A study is just that

In the 21st century scientific studies are published just about every day. And some are recalled because the evidence is faulty or the logic weak. A recent study in Science seems to be a little different in that the scientists do not come to a definitive conclusion.

The study was based on the fact that there has been a forty-fold increase in the rate of earthquakes in Oklahoma between 2008-13. About 20% of these earthquakes greater than magnitude 3.0 have occurred around the small town of Jones since 2008. Researchers have linked this increase to a near doubling in the volumes of waste water disposed of in the central Oklahoma region between 2004 and 2008.

The scientists speculate that the disposal of water in four high-volume wells could be responsible for a swarm of tremors up to 20 miles away. They concluded that the injection of wastewater is "likely responsible" for the swarm with the caveat,"There are thousands of these wells in the US, so only a few appear to be problematic. The difficulties can be avoided but we need to know more about the process so we can give proper guidance to the authorities."

Is fracking the problem?
