Hello Don and All I try to not post here to often among the learned minds but once in a while I spot some things that I wonder about. Don you follow the "creep" data and frank Condon follows ULF data. Just a guess here on my part, but it seems that the two of you might consider a "joint venture" so to speak along with Petra just my thoughts here but being a "watcher" out here I can see a number of "things" falling together but am so darn dumb on this computer stuff I do not know how to put it all together in an "overlay" plan ..concept..projection?? There is a great deal of wisdom and ability here on this board and the Reality of what is happening day to day I truly respect!! Very nice you folk are not trying to "save my soul"" OK? Who out there can tell or talk about the Hilton creek fault that is supposed to be around or South of Mammoth, or Long Valley Caldera area? My main area of study is offshore of Eureka up to Portland ,,CoAxail volcano almost due west of Portland Or. South Gorda Plate.the offset of the south Gorda Plate on the west side north of Mendocino transform which in my minds eye will act as a "lazy susan" as in transfer of south to north lateral movement of present known plates, as far as subduction and so on it seems to me that it will be dependant on what is soon to happen at POPO what goes up must come down. my thought here is that Magma or "jello" is vented and will reduce the existing Pressure or support underneath the "skin" we live upon and take for granted. This Theory depends upon the depth of the "roots" of the solidified extensions of in place Mtn ranges and how "they" respond to increased heating, lest we forget rock does melt!! and as trees loose roots they do fall! usually Down. A small point here< A journey of a thousand miles begins with a broken fan belt or a leaking tire!!! Be Aware just my simple input here! Sincerely Scorpio
