Anti-Drillers Try to Tie VA Earthquake to Marcellus Drilling
It didn’t take long for those who oppose Marcellus Shale gas drilling to try and link the recent earthquake centered near Mineral, VA on August 23 to hydraulic fracturing and horizontal drilling in the Marcellus. Blogs and internet forums said the 5.8 magnitude quake was a result of Marcellus drilling activity, but scientists have flatly stated there is no connection to be made: Marcellus drilling activity is not the cause of the quake. But is there ever a connection between shale gas drilling and earthquakes? The surprising answer is, maybe. But likely not what you think it is.

A new peer-reviewed study from Carnegie Mellon University says that Marcellus gas has less impact on global warming than coal. The study, published in the Institute of Physics Aug. 5th issue of “Environmental Research Letters” is a direct refutation of the Cornell study released in April by professors Robert Howarth and Anthony Ingraffea. The Cornell study was based on sketchy data (admitted to by Howarth & Ingraffea), and pure guesswork. It made the claim that shale gas was worse for global warming and the environment than burning coal.
Now we know why it’s called “The Mighty Marcellus.” New production figures for the first six months of 2011 show that on all counts—natural gas, gas liquids, and even oil—the Marcellus Shale in Pennsylvania is producing a tremendous amount of new energy. Figures for the southwestern part of PA show a 55 percent increase in production over the previous six month period.
Last week, New York State Comptroller Thomas P. DiNapoli made a pitch for taxing the gas drilling industry in New York to create a pool of money that can be used to clean up accidents that may occur. As MDN pointed out (
