Yellowstone Eruption Warning: Massive Volcanic Winter to “Examine the Boundaries of Civilization” | Science | News

The Yellowstone supervolcano is located in Yellowstone National Park, Wyoming State, and is one of 20 other volcanoes around the world, including large caldera volcanoes in Japan, Indonesia and South America. Scientists do not know when Yellowstone will erupt because it is currently filling as its magma chambers fill with molten rock from the Earth’s mantle, an underground layer beneath the crust. A reawakening of the volcano would be devastating for the U.S. as it is predicted to kill at least 87,000 people immediately and two-thirds of the U.S. to be destroyed.

There is no evidence that an eruption of any size should occur soon.

But Bill McGuire, a professor of geophysical and climate hazards at UCL, warned that if an eruption occurs, it could affect the entire world as global temperatures plummet.

He told “Yellowstone is not more likely to erupt in 2021 than in 2020 or any other year in that regard.

“Even if it breaks out, the eruption could be less than ‘super.’

“If – and that’s a big if – in 2021 it starts strong, then a volcanic winter would follow.

“Global temperatures would fall sharply for several years, countering global warming for a while.

“The harvest would fail on a massive scale, while the resulting famine and civil strife would test the limits of civilization.”

The Yellowstone Caldera was formed after three super eruptions over the last 2.1 million years.

Scientists at the Yellowstone Volcano Observatory (YVO) are closely monitoring the Yellowstone area to make possible changes that show an eruption more likely.

They monitor Yellowstone for signs of volcanic activity using seismographs that detect earthquakes and GPS to detect soil movements.

Mr McGuire explained that Yellowstone is not a cause for concern as at least fifty other volcanoes could erupt in 2021.

He added: “As a volcanologist, it would be great for me to see an increase in volcanic activity.

“Unfortunately, the current activity, although attractive and valuable news, is not outside the bounds of normal behavior.

“About fifty volcanoes erupt every year.

“Some, like the Halai Kilauea, are in an almost constant eruption, while others may erupt for the first time in decades or even centuries.”
