Mexico M6.6 earthquake - last gasp of dying spreading ridge

This earthquake is so new they don't even have a fault plane solution for it yet.  Probably oblique-shear, and it was probably lightly felt.  I just like its location.  It's exactly the same as that last mid-Atlantic earthquake, a transform fault near a spread.  Only this one is going down!  What exactly happens when a spreading ridge is swallowed by a subduction zone?  You get a lot of heat under the continent, and it won't be just volcanoes any more.  It'll be the Rockies with volcanoes!

Update:  Exactly the same as the other mid-Atlantic one.
