Well, I knew there was something more then just an earthquake going on. Never heard of the "Back Forty Project". I wasn't able to go to the links because I'm not registered.

Even I knew after 3 days of research that no way that USGS came up with an answer that fast, as to the cause or explanation of it all. Interesting read for those interested.
