Oklahoma M2.8 earthquake - follow the highway!

I am impressed they are getting these earthquakes up the road.  Must be a heck of a lot of injection, since they are almost up into the footwall.  These earthquakes are quite shallow, which I believe, even through the uncertainties must be huge, what with the pitiful instrumentation.  For sure I can't see anything big coming out of this, since it is outside the main mechanism, but we all live for surprises??

Update:  Another earthquake just beside it.  Definitely injection.
