Ancient Irish volcano offers new clues about the development of its modern-day, active 'brothers and sisters'

The team instead demonstrated that magma plumbing systems beneath Earth's surface can fluctuate between solid- and liquid-dominated states, providing an improved view of how active volcanoes evolve through time.
