The United States Geological Survey is attributing a rise in Oklahoma earthquakes to fracking, the process of pumping millions of gallons of chemically treated water and sand underground to extract gas and oil.
The U.S. Geological Survey and Oklahoma Geological Survey found that "a likely contributing factor to the increase in earthquakes is wastewater disposal by injection into deep geologic formations."
According to the joint statement, between October 2013 and April 14, 2014, there has been a dramatic spike in magnitude-3.0 temblors. In total, there have been 183 recorded.
In West Virginia, a number of small earthquakes in Braxton and Gilmer counties have been declared unrelated to Marcellus drilling and fracking, or the injection of millions of gallons of waste water used in fracking back into the earth, sites known as injection wells.
