Artificially-Induced Earthquakes
Officially, there is an area of research devoted to man-made earthquakes. Geologists and seismologists agree earthquakes can be induced in five major ways: fluid injection into the Earth, fluid extraction from the Earth, mining or quarrying, nuclear testing and through the construction of dams and reservoirs.
In fact, there are officially recorded instances of earthquakes caused by human activity.
Geologists discovered that disposal of waste fluids by means of injecting them deep into the Earth could trigger earthquakes after a series of quakes in the Denver area occurred from 1962-1965; the periods and amounts of injected waste coincided with the frequency and magnitude of quakes in the Denver area. The earthquakes were triggered because the liquid, which was injected under very high pressure, released stored strain energy in the rocks.
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.
The plotline of Hammer of Eden, written by best-selling author Ken Follett, revolves around 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.’”
