Two days ago MDN told you about a pair of earthquakes near Youngstown, OH (see 2 New Earthquakes Near Youngstown, OH – Fracking Connection?). That number has now grown. So far there have been a total of 11 measurable earthquakes ranging from 1.2 (not felt by humans) to 3.0 (barely felt by some humans). We suspect most people around Mahoning County didn’t feel anything, but that doesn’t stop mass hysteria when it’s announced that there have been a series of earthquakes and the only thing (supposedly) going on in the area is drilling and fracking.
As we previously pointed out, we are aware of one instance–in England–where fracking over an active fault caused an earthquake. So it can happen. But that’s one time out of 60,000+ horizontally, hydraulically fractured shale wells worldwide (maybe more than that now). Statistically it’s zero. We need to keep perspective in this situation. Initially the Ohio Dept. of Natural Resources (ODNR) said there are no active Class II injection wells in the area pumping waste fluids deep below the surface for disposal, and so the well being drilled and fracked by Hilcorp near the epicenter of the quake looks like the prime candidate as the cause. But one news story we’ve read (below) seems to cast doubt. There may be injection wells, which also have been known to cause earthquakes when injecting near a fault, operating in the area…
