Fracking: 98 more quakes linked to well
Study finds dozens of small temblors hit Youngstown

A fracking waste disposal well linked to 11 earthquakes that rocked the Youngstown area was the likely source of at least 98 additional temblors that were too weak for people to notice, according to new research.

They were discovered by Columbia University researchers who analyzed data collected by Ohio’s regional network of seismometers. The first was a magnitude 1.1 quake that occurred on Jan. 11, 2011, two weeks after the Northstar No. 1 well started injecting fracking waste underground.

The earthquakes were so weak they didn’t trigger alarms until March 17, 2011, when a magnitude 2.1 earthquake was followed minutes later by a magnitude 2.6 earthquake.

Nine additional earthquakes were detected in the following months. They culminated in a magnitude 4.0 earthquake on Dec. 31 that drew national attention and led to new government safety standards for Ohio’s growing fracking-waste-disposal industry.The well shut down the day before that earthquake....

The article goes on to state that evidence has been presented in the Journal of Geophysical Research: Solid Earth that points to fracking having triggered quakes along an unknown fault or faults in the Youngstown area.
