Link between earthquakes and fracking suspected

Link between earthquakes and fracking suspected by Jean Stewart, October 25, 2012, Vancouver Sun
Re: Deadly quake linked to water extraction, Oct. 22
If taking water from reserves deep in the earth can cause an earthquake, how can we possibly think that forcing massive amounts of water deep into the earth (fracking) will not have a similar result? In fracking, water eventually displaces gas (of a different density) or fills previously empty places or creates new reservoirs of deep-earth water. It is like flushing a bladder by bloating the entire abdomen with massive quantities of water. The U.S. Geological Survey has stated the pronounced rise in earthquakes in middle America (in a swath including Colorado, Oklahoma and Ohio) is almost surely a direct result of fracking. Let’s play it safe before we have an accident instead of crying afterward.
