Earthquakes far from injection sites

Just a quick note about yesterday's M2.9 far away from the main zone.  These are probably reacting to stress changes.  If it were possible to do fault plane solutions for such tiny quakes, we would probably see shear, due to the NW strain relief of the main zone.  I still think they may have stopped injection.  Unlike Texas which lumps this in with railroads, there are technical people in OK.
