Oil and Gas 'Do Cause Earthquakes'

The U.S. Geological Survey released a report Thursday connecting thousands of earthquakes to oil and gas operations across the country. The report maps 17 regions where earthquakes have occurred, including the hardest-hit state of Oklahoma, where quakes are now hundreds of times more common than before due to disposal of wastewater left from extracting fuels and from drilling wells, the New York Times reports. The assessment outlined areas of eight other states where oil and gas practices have caused a surge in shaking, and concluded many of them were still at risk for bigger earthquakes in the future.
