I don't have Jagged Earth yet, so this topic could very well be invalidated by changes to Volcano Looming High. With that said, one of the thresholds in Powered By The Furnace Of The Earth says "Add one of your destroyed presence". Since the power is range 0, I would assume that a presence added this way must go to the land targeted by Powered By The Furnace Of The Earth, but I want to confirm.
Also, if there's a FAQ that already answers this question, adding Volcano Looming High to it's tags might be a good idea.
