The number of tremors afflicting oil-rich Oklahoma has fallen since regulators began cracking down on the injection of wastewater from oil and natural gas wells, but the state still faces the highest risk of induced earthquakes in the nation. New seismicity maps released Wednesday by the U.S. Geological Survey show that a swath of Oklahoma and Southern Kansas are likely to experience high-magnitude earthquakes this year. USGS also identified the Raton Basin, straddling Colorado and New Mexico, as a high-hazard area. Oklahoma in recent years has seen a steep rise in the number of earthquakes clocking in at magnitude of 2.7 or higher. Geologists, including the USGS, attribute that spike to increased wastewater injection deep underground. The state more than doubled its crude output from 2011 through 2015 […]
