Fracking Spurred Biggest Earthquake Yet

The Earth Institute of Columbia University reports Wastewater Injection Spurred Biggest Earthquake Yet, Says Study "A new study in the journal Geology is the latest to tie a string of unusual earthquakes, in this case, in central Oklahoma, to the injection of wastewater deep underground. Researchers now say that the magnitude 5.7 earthquake near Prague, Okla., on Nov. 6, 2011, may also be the largest ever linked to wastewater injection"

There's some mitigating info in the article. It's hard to prove what caused a specific quake and other human activities are believed to cause quakes, not just fracking and if anything fracking causes small quakes. Still, I wonder, and I'm waiting for some study on fracking causing quakes near nuclear power plants changing the seismic assumptions of the site.
