reports for Energywire. "During that time company officials and regulators would confer about how to change the operation. If there were to be a quake of magnitude 3.5, the fracking operation would shut down until company officials and regulators confer about whether the operation can continue."
"For quakes between magnitudes 2.5 and 3, the Oklahoma Corporation Commission is to contact nearby operators who are expected to implement their internal plans for earthquake mitigation," Soraghan writes. While the guidelines are voluntary, "OCC has the power to shut down an operation to address earthquake problems."
Many in the oil and gas industry praised the guidelines, Soraghan writes. Until recently many in the oil and gas industry, along with Republican Gov. Mary Fallin, refused to acknowledge a link between fracking and earthquakes. That changed last year when the Oklahoma Geological Survey, which originally denied any link between seismic activities and fracking operations, said "that most of the quakes are 'very likely' triggered by oil and gas activities." In March OGS for the first time released maps of earthquakes attributable to human activity.
