M5.1 Mexico subduction zone

This is a nothing earthquake for the region, but I love it!  It is my prime candidate for the next M9, since I don't think they've had one in history.  Could be wrong, but that M8 doesn't count.  This is the cleanest, smoothest zone that hasn't had a clearing earthquake.

Lest you panic, there are lots of these zones, and we only get one every 10 years or so.
