John, I mostly lurk on psn-1 because I'm not an electronics whiz, nor 
geological expert (ie: nothing to add, but stuff to learn) --- I JUST read 
something about a Samoan volcano coming to life -- this is allegedly in (or 
near) the area where the mantle material was found. Maybe that is a clue as 
to why the emergence of this deep material at this time -- something is 
happening DEEP and is slowly coming to life?  Just a thought.

Fascinating group of people here....
Adrienne
