Magma locked in cold storage before volcanic eruption: Study
US-based scientists have proposed a new volcanic eruption theory that magma is locked in a cool, crystalline dormant system which needs a huge heat infusion to erupt. The theory contradicts the older view of a molten rock reservoir in the crust. The study was based on California's super-eruption that occurred 765,000 years ago, spewing 650 cubic-kilometres of lava and ash.
