London, August 9 : U. S. researchers say that the relatively tepid temperature of the Yellowstone Caldera indicates that the supervolcano may be on its last legs.

Derek Schutt of Colorado State University has revealed that the supervolcano in Yellowstone National Park has been found to be about 1450 degree Celsius hot at 80 kilometres beneath the Earth’s surface, which is only lukewarm for a supervolcano.

He and his colleague Ken Dueker, a researcher from the University of Wyoming, estimated the temperature of the plume beneath the Snake River Plain, south-west of the Yellowstone caldera, using the knowledge that temperature affects how seismic waves travel through rocks.
