Man-made earthquakes may seem like something out of the X-Files, and it's probably only a matter of time before the idea is picked up by Hollywood. This year, best-selling thriller author Ken Follett released his latest book, Hammer of Eden, about a terrorist group threatening to level San Francisco with a man-made earthquake. When asked by Salon Magazine how real is the idea of a man-made earthquake, Follett replied that "Some of the seismologists told me, 'There's no way this could happen.' But others gave sad little shrugs and said, 'It's hard to say. Who knows? Maybe. It's within the realm of possibly.'"
