ODNR Says No ‘Felt’ Earthquakes from Injection Wells Last 5 Yrs

On Dec. 31, 2011, the Youngstown, OH area experienced a 4.0 earthquake that was later determined to be caused by a wastewater injection well (see Youngstown Earthquake and Fracking: Is There a Connection? and ODNR Finds Youngstown Injection Well Caused Earthquakes). The Ohio Dept. of Natural Resources (ODNR) later enacted new regulations to prevent future occurrences of earthquakes from either injection wells or fracking itself (see Did ODNR Overreact & Set Earthquake Detect Bar Too Low?). As we pointed out in 2014, the new rules would have shut down the Cleveland Browns stadium–if all of the fans were to begin stomping their feet it would create an “earthquake” greater than the allowed limits set by ODNR. Since the new rules were enacted there have continued to be earthquakes in Ohio, but not “felt” earthquakes from injection wells (see Study Says Series of Unfelt Earthquakes in OH from Utica Fracking). Typically an earthquake must reach 2.5 on the Richter scale to be felt on the surface. Since spring of 2012, there have been no major (above 2.5) earthquakes in Ohio related to injection wells, although there have been a few felt earthquakes supposedly tied to fracking over an active fault (see OH Researchers Confirm Hilcorp Fracking Caused Low-Level Quakes). Now five years later, the ODNR is patting itself on the back, taking credit for the reduced number of earthquakes tied to injection wells, because (they say) of their super-restrictive regulations…
