New Madrid M3.3 earthquake



This is exciting.  All NM ever produces is tiny earthquakes along the track of the old earthquakes.  I'm always looking for any sign that it will expand and come back to life.  As I have mentioned, the big ones sucked all the life out of the zone, in the form of stress relief.  In order for it to revive, it has to expand out of its stress hole, or the hole has to start picking up stress, much like a collapsing tunnel.  This earthquake is consistent with either possibility.
