But the agency has not issued a directive to mask down any disposal wells in the area, which is part of what is have knowledge of as the Arbuckle formation.

«Everything is still in the initial stages right now,» Skinner said, «but [shuttering some surges] is a distinct possibility.»

Not a traditional earthquake zone

An open plain safer known for tornados, Oklahoma became an earthquake hot zone around 2011, extraordinary California in magnitude 3 or greater earthquakes in 2014.
