Oklahoma knew fracking caused earthquakes but stayed quiet to appease energy industry

Oklahoma has suspected for years that fracking caused earthquakes, but they stayed quiet about the connection under pressure from the oil industry.

The Oklahoma Geological Survey (OGS) finally admitted a possible link in more than a year ago between oil and gas extraction and the recent outbreak of earthquakes in the state — which last year experienced 1.6 quakes per day of magnitude 3 or greater.

That’s three times as many as California.

The OGS joined a U.S. Geological Survey statement in October 2013 that found human activity, including wastewater disposal, could be a “contributing factor” in the surge in earthquakes.

That angered the state seismologist’s boss, University of Oklahoma President David Boren, and oil executives, according to emails obtained by EnergyWire.
