Interesting background to the wells Grey-Clearwater volcanic field @ the head of the Chilcotin hotspot.
Of interest here is the large disparity between eruptions which appear to pop up in series.
There is @ present a problem in working out whether the eruptions are the latest stage of recompression of the Garibaldi backarc basin or whether they are the early stages following crustal relaxation from a megathrust earthquake (9+) & bloody great big tsunami.
As the relaxation vector passes through the Canadian shield, Greenland & terminates in iceland (W. Iceland rift) a relaxation of the crust would result in an eruption series in the W part of the rift near reykjavik (dormant for about 2500 years nowadays). As a result my best guess is that the eruption series is a latest stage of recompression event & a rebound/long duration mercalli X (r/lx) event is forthcoming & a bloody great big tsunami @ vancouver @ the washington & N. Oregon coast is due in the relatively (a few centuries) near future.
Interesting to see some of the landscape.
Have a nice day: Ag
