More evidence of induced earthquakes in other states, as KGS monitors background activity in eastern Kentucky

News reports from Pennsylvania indicate that hydraulic fracturing (fracking) of Utica Shale wells was apparently the source of small earthquakes last year in Lawrence County, Pa. The April 2016 events were the first known fracking-related earthquakes in Pennsylvania. KGS continues to monitor the background seismicity in eastern Kentucky, where subsurface wastewater injection is ongoing and fracking is used to produce oil and gas in the Berea Sandstone and the emerging, unconventional Rogersville Shale plays.

For more on this issue, here is a newly-released KGS fact sheet on hydraulic fracturing in Kentucky.
