Possible Man Made Earth Quake?

Earthquakes typically occur 3+ miles under ground. The earthquake that hit the US eastern coast occurred one mile underground. There are many possible reasons for the earthquake. Natural, Fracking(pressurized fluid to crack rock layers to release oil, gas, etc...) or test gone wrong. We all know that the govt has tested numerous crazy weapons. Sonic guns, mind control, Teleportation, and anti gravity. Who's to say they don't have an Earthquake machine? It is not out of the realm of possibility. I don't think that they would test it that close to D.C. Another Thing is that it was Fracking. In Mineral Virginia there are three fault lines. A company could have been Fracking and hit one of them. Of course they would not tell any one. That's bad PR for the Mining industry and for their company. I have more research to do but I am pretty set on this being a man made Earthquake. Also check out this http://youtu.be/OHyAuQ-U47g
