Oklahoma M3.9 earthquake

This isn't my M5 thrust yet, but things are heating up with the warmer weather.  This is an M3.9, just below the magic M4 we seem to need for a fault-plane solution.  If we had this, we would probably see another strike-slip on the shear wing.  All of this adds displacement to the thrust zone.

Earlier there had been signs that a shear wing would go down to the city, but I don't know if this will happen now.  Once we get up to M6's, we'll get a second shear wing, and the resemblance to New Madrid might even become obvious to USGS people.  :)
