Hydraulic fracturing rarely linked to felt seismic tremors

Researchers find only one hydrocarbon-producing area where production is linked to increased seismic activities at the regional scale

University of Alberta

EDMONTON (June 26, 2017)--New research suggests hydraulic fracturing and saltwater disposal has limited impact on seismic events.

For the past two years, UAlberta geophysicist Mirko Van der Baan and his team have been poring over 30 to 50 years of earthquake rates from six of the top hydrocarbon-producing states in the United States and the top three provinces by output in Canada: North Dakota, Ohio, Oklahoma, Pennsylvania, Texas, West Virginia, Alberta, British Columbia, and Saskatchewan.

With only one exception, the scientists found no province- or state-wide correlation between increased hydrocarbon production and seismicity. They also discovered that human-induced seismicity is less likely in areas that have fewer natural earthquakes.

1. So Oklahoma will shake itslelf to peices.

The anomoly that it is.. all is safe except OK, who has somehow pissed off the god of fracking.
