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.
