Chesapeake Energy, the owners and operators of the fracking well that exploded yesterday in Pennsylvania, have stopped all fracking operations in the company’s Eastern Division until they can figure out why the well exploded.

Thousands of gallons of toxic fracking fluid were dispersed into the surrounding area as a result of the explosion, flowing over Pennsylvania farmland into a nearby creek.

“The cause of the equipment failure is undetermined at this time, and as a precaution, Chesapeake has voluntarily shut down all completion activity in its Eastern Division,” Chesapeake said in a statement released via the company’s Facebook page at 8:41 p.m. EDT.  “A full investigation will be conducted to determine the root cause of the failure, evaluate best management practices and make any and all necessary corrections before returning to normal operations.”

UPDATE: At 10:38 p.m., Chesapeake has issued another statement via the company’s Facebook page saying that they’ve “achieved full wellhead integrity.” Read the whole thing here.
