New Madrid fills to the rift walls

New Madrid should be totally dead.  With those M7+'s it should have shot its load, to never bother us again.  Yet it refuses to die.  :)

This new pattern is amazing!  In fifty years (ten if they inject), the thrust zone (middle) is going to fill NW-SE to the rift walls (red lines).  As we know, this area is an amazing overprint of a failed rift on top of the megathrusts.  What a mess!  If it fills to the edges, then the shear zones will be out of the old stress shadow, and I think we can expect something like an M8.  We don't really need injection here since it is slurping directly from the river.
