Fracking, And Gas Production In The US
I always believed that fracking really had nothing much to do with the incidence of earthquakes, especially intense ones. In fact, Common Sense 101 leads to the knowledge that smaller quakes naturally relieve plate pressure and help prevent large quakes. Well, now there is confirmation of all this.

Quote:From the Heartland, More Fracking, Fewer Earthquakes

A new analysis of Oklahoma Geological Survey (OGS) data undertaken by Energy in Depth shows the amount of monthly earthquakes in the Sooner State has decreased 86 percent from its peak in June 2015. Concurrently, there has been an 11 percent increase in oil production and 81 percent increase in the number of operation oil rigs in the state over the past calendar year. These numbers help reinforce what the scientific literature has long shown: Fracking is not the cause of the increases in induced seismicity.

Researchers at the University of Alberta released a study in June concluding fracking has had a limited impact on earthquakes in the United States and Canada. Further, a database tracking earthquake sequences proposed to have been induced or triggered by human activity since the 1800s, administered by researchers at two universities in the United Kingdom, shows only 29 earthquakes have conclusively been linked to fracking. The U.S. Geological Survey (USGS) itself, on its “Myths and Misconceptions” page for induced seismicity, says, under “Fact 1”: “Fracking is NOT causing most of the induced earthquakes.”
Have a Gneiss Day!
