A 4.0M earthquake struck Wyoming .. near midnight local time, going into the early AM , May 16, 2013.
Within 3 miles of the earthquake epicenter is a large google earth placemarked Phosphate mine.
The depth of the earthquake is at what I call “fracking depth”… normally the depth we see most of the OK, AR, CO earthquakes, at the drilling / pumping operations.

We have seen “mine” earthquakes before, in the near term past — a sign of building pressure upon the craton.. showing at weak spots in the crust before the greater movement occurs (within weeks to a few months at the most).
I base the weeks/months time frame for larger movement, based upon PAST similar occurrences in 2011, and 2012.
