Is the Yellowstone caldera fizzling out?
This adds to suggestions that the plume has disconnected from its heat source in the Earth’s core. If this is true, it means the plume could be dying – and that the sequence of mega-eruptions could come to an end. “If it doesn’t have clear source, as it rises eventually the plume will die out,” says Schutt.
Let’s hope so. A Yellowstone explosion could be a civilization-ending event, and there’s not much we can do to prevent it, at least with current technology.
