Ohio finally calls it a day with injection earthquakes

Article

To satirically paraphrase:  "We know it doesn't trigger earthquakes, but we can't take a chance on proving it actually does.  We've got thousands of these wells, and more are expected."

Oh well, I suppose the earthquakes will stop now, unless they have totally opened up the system, as with Arkansas.  Still Ohio is just one big injection zone, so we must expect future action.  I'll just have to place my faith in Texas and Oklahoma!
