Yellowstone supervolcano: ‘Anomaly’ could explain volcanic activity

The research continued: “We conclude that a plume rising from the CMB is the ultimate heat source driving Yellowstone volcanism.”

According to the study, the volcanic plume, around 600 to 800 ºC warmer than surrounding areas, is responsible for the volcanism witnessed in Yellowstone.

Global topography, they said, would not detect such a plume, and they may also exist elsewhere too.

Barbara Romanowicz, a planetary seismologist at the University of California, told Earth Magazine in 2018: “Yellowstone presents a unique opportunity to image a plume under a continent.
