Lawmakers Address Surge in OK Quakes

Researchers from Cornell University published in the journal Science a report on the “Sharp increase in central Oklahoma seismicity since 2008 induced by massive wastewater injection.” Researchers concluded that they found earthquakes could be induced as far as 19 miles from the injection well, much farther than the current range of 3 miles used to diagnose induced earthquakes.

Meanwhile, state lawmakers in Oklahoma, Texas and Kansas are making a marked effort to increase dialogue about earthquakes linked to fracking. According to the Associated Press, “regulators from each state met for the first time in March in Oklahoma City to exchange information on the quakes and discuss toughening standards on the lightly regulated business of fracking wastewater disposal.” Officials are in particular examining potential links between the amount and pressure of water used in injection wells, with Oklahoma Governor Mary Fallin recently signing legislation that requires the daily collection of information on well volume and pressure by well operators.
