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. :)
