Leahy, D (2015, February 5). Fracking-induced earthquake puts B.C. gas bonanza on shaky ground. Retrieved on March 1, 2015. From http://www.vancouverobserver.com/news/ fracking-induced-earthquake-puts-bc-gas-bonanza-shaky-ground
Recently the small town of Fox Creek of northern Alberta experienced the largest earthquake caused by hydraulic fracking, it was a 4.4. it used to be that if a fracking site pumped less than 100,000 cubic meters every month, then there would be no earthquakes. But as time goes on more and more fracking wells have been constructed and the limit of water pumped into a well has gone down.
Many people do not understand that what they are doing in directly causing the earthquakes. Denis Lavoie, research scientist with the Geological Survey of Canada (GSC), travels the country giving speeches in an attempt to bring attention to this important and urgent subject. He predicts that these earthquakes will only increase, they have not yet reach the maximum damage that could be caused on the surface, Lavoie hopes to stop the fracking before the limit is reached.
