Mysterious Underwater 'Fountain' of Magma Found Beneath Yellowstone

•, Sputnik News

Researchers Peter Nelson and Stephen Grand at the University of Texas Seismic have carried out a seismic analysis of the Yellowstone Supervolcano which confirmed that the volcano contains a powerful plume — a "fountain" of magma rising rapidly from the depths of the Earth's mantle, according to the journal Nature Geoscience.

"The Yellowstone hotspot, located in North America, is an intraplate source of magmatism, the cause of which is hotly debated. Some argue that a deep mantle plume sourced at the base of the mantle supplies the heat beneath Yellowstone, whereas others claim shallower subduction or lithospheric-related processes can explain the anomalous magmatism," the researchers said.
