A 3.4 magnitude earthquake, showing at -3.0 km 'depth'.   Negative depth is an impossibility, other than being on the surface. Upon visual inspection of the area using google earth, clearly there is a very large chemical factory, and coal processing plant of some kind. Leading to logical speculation that this "surface earthquake" may have been an actual large blast of some kind at the chemical (or coal) factory. Listed chemcial company near this surface "earthquake": FMC Industrial Chemicals Group Highway 374, Green River, WY 82935 ‎(307) 875-2580 ‎fmcchemicals.com Unlisted coal plant, if you can find the name let me know!
