Abandoning years of official skepticism, Oklahoma’s government on Tuesday embraced a scientific consensus that earthquakes rocking the state are largely caused by the underground disposal of billions of barrels of wastewater from oil and gas wells.
The state’s energy and environment cabinet introduced a website detailing the evidence behind that conclusion Tuesday, including links to expert studies of Oklahoma’s quakes. The site includes an interactive map that plots not only earthquake locations, but also the sites of more than 3,000 active wastewater-injection wells.
The website coincided with a statement by the state-run Oklahoma Geological Survey that it “considers it very likely” that wastewater wells are causing the majority of the state’s earthquakes.  MORE
