Yellowstone’s supervolcano may be fueled by something unexpected

Scientists may have cracked a long-standing mystery about Yellowstone's supervolcano. Rather than being fueled by a plume of hot rock rising from deep within Earth's core, new research suggests a broad current of heated mantle—think of it as a 'mantle wind'—pushes rock beneath Yellowstone, triggering magma formation much closer to the surface. This process helps explain how the supervolcano maintains its massive underground network of molten rock and stays active over geologically long periods. According to ScienceDaily, this discovery could reshape our understanding of how supervolcanoes work.
