Hello! I was wondering, is the Cascade Volcanic Arch inactive relative other volcanic archs like it? If so, why?
And why is the great basin so inactive? There is evidence of (Geologically) recent volcanism (like in the case of Sunset Crater) but it seems rather sporadic compared to other rift zones.
