Fully Appreciated Don ****

I guess the first thing to do is make sure that others would agree that the ring zone is parallel with the general directional trend of the Juan De Fuca/Cascadia subduction zone. I have looked closely at the theoretical P-103 from the USGS, and I see that the map (from Don) is highly indicative of the directionality and distance from the landmarks given. It is a good map.

If that is agreed upon, then I must fix the lat-lons of a study area. In my mind a study area can be a large areal, with sub-regionality used to further constrain findings due to cross faulting and historical depth of seismicity.

Comments Appreciated, and thanx again Don.
