Oklahoma earthquake swarm - NW fault completely defined

There have been a heck of a lot of earthquakes overnight.  All along the NW thrust of our growing New Madrid.  Still on for the M4.5 by the end of the week, but I wasn't really expecting this swarm.  Normally they just go in big chunks.  This means the faults aren't quite as smooth as Arkansas.

Once the big thrust earthquake happens, we can expect the shear wing to be defined.  It will cut right through the centre of the city.  This is nothing like the horror in the Pacific, but it is our own little horror, with lots of cracked plaster, and falling chimneys.  As our baby continues to grow, we can expect bigger action, all the way to the penultimate M7.8, although, truly, they might stop injecting by then.  :)

Am I a mystical guru predicting all this?  No.  It's just physics.
