THE YELLOWSTONE volcano has been “intensely monitored” by a team of scientists and volcanologists concerned by a 400-mile-long plume of hot magma that is rising beneath the surface of the Earth.
The Yellowstone volcano has erupted three times in history – 2.1 million years ago, 1.2 million years ago and 640,000 years ago. Scientists have previously revealed that, should an earthquake occur, it could take less than two weeks before a catastrophic reaction event with the potential to wipe out three-quarters of the US is triggered. Now, it is the job of geologists to “intensely monitor” a large area of molten rock directly below the surface of the supervolcano, it was revealed in a documentary.
Volcanoes typically erupt when molten rock, known as magma, rises to the surface following the Earth’s mantle melting due to tectonic plates shifting.
