Central Kamchatka Depression, Idiot.
"We envision two petrogenetic models, which relate the composition of
erupted magmas to the subduction parameters beneath the CKD. The first
model suggests that mantle temperature governs melt-peridotite
equilibria and favors generation of andesitic primary melts in cold
mantle regions above the shallowly subducting Pacific slab edge."

This is where upduction occurs dude, upduction.

Yep, subduction in phase with surrection ...
That a good observation, except that the timing is not correct.
... also the process cannot be explain in term of PE (planetary
expansion ) except in the True Geology approach based on the UPL or
Universal Pressure Laws
I wish Oriel36 would interfere there to put his grain of salt ...
Please, by the way, do not pick too much on George, the poor chap is
suffering from an orphan dizzeaze called 'delusion of grandeur' as a
painful side effect of that diabetes of his. He believes he's a genius
and any demonstration of the opposite could kill his ego and hence the
bio structure supporting it...
see?
why in your view does he call himself George ?
Lost his bearing completely indeed ...does not even know who he
is ...
He even talks about Geology while not knowing the first word about
it ... poor George !
