This super volcano could wipe out the US and kill billions



  • The super volcano in Yellowstone National Park could trigger an "ultra disaster," warns a writer of extinction events.
  • The complete eruption of the volcano last occurred 640,000 years ago, uninhabitable states.

If there were not enough disasters to worry about, a recent book brought another terrible possibility back into the public eye. Bryan Walsh's "End Times" highlights, among other things, the outbreak of the Yosemite super-volcano in the United States as an event that could destroy many lives on this planet.

Fortunately, the Yellowstone volcano in Wyoming does not break out very often. This was the last time before 640,000 years ago. No one knows for sure when it will explode again, but some measures could happen at any time.

In this case, the eruption would carry about 240 cubic miles (1

9459010) of stone, dust and ashes to the sky, as was the case with the last major explosion. There would also arise a flow of magma that would bury the area in a radius of 40 miles. Chunks of Colorado, Wyoming and Utah would end up to three feet of ashes . Parts of the Midwest would be covered with at least a few centimeters of such ashes and become dark. And if you think that does not sound good, emitting dust and toxic gases like sulfur monoxide into the atmosphere would create a sour veil around the planet that reflects sunlight. This would lead to a dramatic cooling of the global climate that would last at least several years.

This will also lead to destroyed crops and destruction of the power grid. Without sunlight, heat and food, a significant loss of life would occur. How terrible? As Bryan Walsh writes in his statement in The New York Times, a 2015 report for the European Science Foundation on extreme geo-driving described what might happen as "the greatest catastrophe since the beginning of civilization."

More specifically, Jerzy Żaba, geologist at the Silesian University in Katowice (Poland), said in an interview that, according to his estimate, around 5 billion people [1945901] would die of starvation due to climate change. "If Yellowstone blows, he suggests that the only thing left to do to survive is to flee North America." Imagine American refugees trying to get to South America or Europe.

Bryan Walsh calls Walsh writes: "Experts on existential risks are largely in agreement that super volcanoes – of which there are 20 are based on this scenario without much exaggeration as an" existential risk ", not only for the US but for the whole world The planet is – the natural threat that represents the highest probability of human extinction. "

Yellowstone National Park, Wyoming, United States big question is, of course, when the Yellowstone Supervolcano will break out.In the seismically active area of ​​Yellowstone National Park there are about 3,000 small Earthquakes a year, but the catastrophic explosions are rare. In addition to the so-called "Lava Creek outbreak" 640,000 years ago, the volcano completely exploded around 1.3 million years ago and 2.1 million years ago, meaning between 660,000 and 800,000 years ago. Of course, no one knows for sure when it will happen next, which is why Walsh believes that more resources must be devoted to the study of volcanoes.

Currently, the FAA spends about $ 7 billion on aviation safety each year, while volcanic programs, which may potentially claim significantly more victims, spend only $ 22 million on study expenditures.
