AN ABNORMAL “river” of lava deep underneath Yellowstone’s supervolcano could cause it to erupt at any time and “wipe out western America”, scientists have warned.
It is feared that the Yellowstone volcano would completely wipe out from the National Park down 215 miles to Mexico and kill millions with its deadly ash cloud.
Researchers Peter Nelson and Stephen Grand from the University of Texas published their discovery of the “anomaly” in the journal for Nature Geoscience.
They describe the river as a “single narrow, cylindrically shaped slow anomaly, approximately 350 km in diameter that we interpret as a whole-mantle plume”.
According to the two researchers, it is the “deep origin for the Yellowstone hotspot” which is “currently beyond the resolution of global tomography models”.
If the supervolcano were to erupt, the miles of lava running beneath it would cause catastrophic damage above ground.
360,000 people would instantly be killed and millions more would die as ash clouds cover the sun.
Fears of an imminent mega-eruption were sparked last year when a “swarm” of 1,400 mini earthquakes took place at Yellowstone National Park.
At the time – when the hotbed under the volcano was estimated to be 51 miles long – scientists believed the volcano would only kill 90,000 people.
Researchers have long argued about the source of Yellowstone’s heat, but all agree that a volcanic eruption in the park would be catastrophic.
The two researchers, from Texas, believe they have now found proof the “river of lava” does exist under the supervolcano. read more…
