Scientists say fracking is part of why Oklahoma now rivals California in quake activity.
This isn't just the stuff of comic-book villains: Real humans in the real world—actually, in Oklahoma, of all places—can cause earthquakes.
Scientists have known about man-made earthquakes for decades. They've blame some reservoirs for seismic activity because reservoir water that trickles underground ends up lubricating faults that then slip—or, quake—as a result.
