The Yellowstone has shown some signs of seismic activity. The Fears have risen that the supervolcano could erupt soon.
Terrifying new footage shows steam and ash rising beneath the surface of the 2,805m tall volcano in Wyoming, US, fuelling fresh concern it could be about to blow.
The massive volcano last erupted 70,000 years ago but a recent unexpected spike in seismic activity around the globe, which has resulted in devastating earthquakes in Asia and Ecuador in the last week, has unsettled nerves.
And now a video, uploaded to YouTube by user KatMartin2016, has emerged shows the super volcano simmering and with bright flashes of volcanic activity, especially on the far left of the screen.
If the volcano were to erupt, it could cause global catastrophe, particularly in the US where two-thirds of the country would become immediately uninhabitable as the large spew of ash into the atmosphere would block out sunlight and directly affecting life beneath it.
The massive eruption would be a staggering 2,000 times as powerful as the one from Washington’s Mount St Helens in 1980.
That caused 57 deaths and $1.1bn worth of property damage after it deposited ash in 11 different states and five Canadian provinces.
Fears Yellowstone could violently erupt soon have been exacerbated after parts of a river near to it began boiling at the end of March, with geologists believing that a new volcanic vent opened up beneath it.
