Virginia and Oklahoma earthquakes

After watching trucks thrown a few hundred feet in Texas, perhaps it is hard to get excited about earthquakes.

Ok had an M4 in the middle of nowhere (big square).  We can assume it is injection but we await more to be sure.  Virginia had an M2.5 at the lower edge of the earthquake zone.  If this trend continues, we are seeing some sort of extension of the zone which is most likely brought around by natural fluids.  Note that Arkansas continues with low activity.
