Abstract
- The article reports that Derek Schutt and Ken Dueker estimated the temperature of the plume of the supervolcano beneath Yellowstone National Park in Wyoming with the use of seismic waves. The supervolcano exploded 642,000 years ago, covering half of what is now the U.S. in ash. The source of its eruption is not certain, yet suspicion focuses on a large plume of hot mantle. The temperature of the plume is around 1450 degree Celsius which suggests an end to the sequence of mega-eruptions.
