Rather than quote some activist or industry site that has a bias, I choose the US Geological Survey, who are recognized by serious scientists as the experts. Here is a quote form their publication that addresses the question of induced earthquakes, "Fracking is NOT causing most of the induced earthquakes." These induced earthquakes, usually in therange of 1 or 2 on the Richter Scale (not enough to do any damage) come form liquifaction. This is caused when left over water from fracking is dosposed in the ground. If it is taken elsewhere, which is now done, no quakes are caused. Please. I have read all of the biased publications. If you are serious about solving the problem, look at the facts and choose the best paths currently available to us, no just what is popular with the cool kids.
