[I still remember working on and being fascinated by lahars being an engineering geologist in Washington State (and from my time studying in New Zealand), although (of course) not to this level of detail/focus]

Water stored in the mantle for millions of years may be linked to continental volcanism

The mantle transition zone (MTZ), which occurs 410–670 kilometers below Earth's surface, may store several oceans' worth of water. This water, which is carried to such depths by subducting tectonic slabs, is stored in minerals like ringwoodite and wadsleyite.

Large magma bodies found beneath dormant volcanoes, surprising scientists

New Cornell University led-research challenges the long-standing belief that active volcanoes have large magma bodies that are expelled during eruptions and then dissipate over time as the volcanoes become dormant.
