Picture a volcanic eruption: fiery lava and smoke billowing skyward as a towering mountain empties its over-pressurized belly of a hot meal. At least, that’s how most of us think it works. So you can imagine volcanologists’ surprise when they discovered that Mount St. Helens, which was responsible for the deadliest eruption in US history, is actually cold inside.
Apparently, it’s stealing its fire from somewhere else.
