Yellowstone volcano: How scientists ‘intensely monitor’ rising column of HOT MAGMA

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.

“We can reconstruct a 3D picture like an MRI scan by recording thousands of earthquakes.”

The documentary then reveals how the mapping system of more than 150 seismometers has identified a 400-mile-long magma plume rising from the Earth’s core.

Should this reach the surface, there could be catastrophic effects.

The last eruption of Yellowstone produced around 2,500 times more volcanic material than the 1980 eruption of Mount St Helens.
