Report is released with media coverage claiming that fracking has caused earthquakes in town that never had recorded earthquakes before.
Confirmed: Fracking practices to blame for Ohio earthquakes

This map shows the intensity of shaking in the area of a magnitude-3.9 earthquake that struck near Youngstown, Ohio, on Dec. 31, 2011. Research has linked this earthquake to the underground injection of wastewater from fracking.
Wastewater from the controversial practice of fracking appears to be linked to all the earthquakes in a town in Ohio that had no known past quakes, research now reveals.

Before January 2011, Youngstown, Ohio, which is located on the Marcellus Shale, had never experienced an earthquake, at least not since researchers began observations in 1776. However, in December 2010, the Northstar 1 injection well came online to pump wastewater from fracking projects in Pennsylvania into storage deep underground. In the year that followed, seismometers in and around Youngstown recorded 109 earthquakes, the strongest registering a magnitude-3.9 earthquake on Dec. 31, 2011. The well was shut down after the quake.
Scientists have known for decades that fracking and wastewater injection can trigger earthquakes. For instance, it appears linked with Oklahoma’s strongest recorded quake in 2011, as well as a rash of more than 180 minor tremors in Texas between Oct. 30, 2008, and May 31, 2009.
The new investigation of the Youngstown earthquakes, detailed in the July issue of the journal Geophysical Research Letters, reveals that their onset, end and even temporary dips in activity were apparently all tied to activity at the Northstar 1 well.
