This is what a man-made earthquake sounds like. It's from Oklahoma (magnitude 5.6). I recorded it this morning here at Pigeon Hill in Steuben, Maine. About 7 seconds into the sound clip you can hear a California earthquake (also 5.6). The Oklahoma quake begins at about 24 seconds.

Oklahoma used to be a quiet place. In just a few years' time the fracking industry has turned it into one of the most seismically active — and riskiest — regions in North America, second only to Alaska.

Is this really the world we want to create for ourselves?
