Watts Up With That?

From the UNIVERSITY OF ALBERTA, another political tool of the left bites the dust.

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

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.

The anomaly was in Oklahoma, where seismicity rates have…
