Yellowstone volcano at 80 kilometres beneath the Earth's surface it's about 1450 °C, say researchers – which, for a supervolcano, is only lukewarm.
That doesn't mean we won't get another eruption. The last explosion, some 642,000 years ago, created the Yellowstone caldera and blanketed half of the present day US in ash.
But Derek Schutt of Colorado State University believes the relatively tepid temperature means the supervolcano could be on its last legs.
Yellowstone National Park in the US is one of a few dozen volcanic hotspots around the world, along with the likes of Hawaii and Iceland.
What causes it to periodically erupt is not clear. Some researchers think it is disturbances in the top 200 kilometres of the Earth's interior, but increasingly the evidence is pointing to a large plume of hot mantle rising up from much deeper, melting its way through the crust.
