Will Yellowstone volcano be a doomsday mega-eruption?

For years, the possibility of humanity disappearing under the effects of the mega-eruption of Yellowstone volcano in the USA has been a recurring theme in digital media. A simple tour on the web lets you see how it’s done. This big bang (which will undoubtedly happen) is already known as the ‘end of the world’ and will surely end all humanity. But will it really be like this?

Scientists confirm without ignoring that when the Yellowstone volcano erupts, it can trigger disastrous consequences for the entire planet, creating a new Ice Age. And approximately every 600,000 years, this giant awakens violently with each eruption that can cause craters tens of kilometers in diameter. Given that the last eruption occurred 640,000 years ago, theoretically it shouldn’t take long for the next eruption to occur.

It is considered a supervolcano as its eruption power can exceed 100 times that of a conventional volcano. In fact, it is one of the eruptions that geologists around the world fear most. The UN has warned that the winter that will cause this extraordinary eruption will trigger a worldwide famine., because it would leave food reserves to survive only a few months. And the repercussions, if anything, would last for decades.

Scientists have confirmed that Yellowstone has experienced only three eruptions in the last two million years. “It will erupt again, but it is unknown when or at what scale,” said Michael Branney, a volcanologist at the University of Leicester.

But when that happens, the ash will affect nearly the entire United States and Canada, rendering most of North America uninhabitable. According to simulations performed by various groups of scientists, People residing within a radius of 1,000 kilometers will die from the explosion and the emitted ash blocks sunlight, causing temperatures on the planet to drop by as much as ten degrees. This sudden decline could take decades, dramatically changing many ecosystems.

A risky solution

NASA has come to explore ways to cool the volcano and fend off the threat its awakening would represent. Brian Wilcox, a former member of NASA’s Advisory Council on Planetary Defense and other scientists working to prevent asteroid and comet strikes, noted: “I came to the conclusion that: The threat from a supervolcano is significantly greater than the threat from an asteroid or comet.

Wilcox detailed one of NASA’s plans to cool the magma chamber and eliminate the risk of an imminent eruption. The plan includes drilling directly into the chamber and pumping tons of water to cool it.thus creating a mega power plant. But any attempt to puncture the magma pocket can weaken its integrity and cause an eruption. This is an extremely risky operation, so the project is far from being executed at the moment.

The University of Utah has issued a message of calm for its part, reassuring that there are no visible signs of a catastrophic eruption at this time. In addition, they state Yellowstone is the most geologically monitored area on the planet.24 hours a day, it is constantly monitored by more than 40 seismic stations that continuously record the movements of the earth in that area.

No, humanity will not perish

However, given the alarmism in many media’s approach to this issue, the Yellowstone Volcano Observatory itself, which is responsible for monitoring everything that happens inside, recently released a memo explaining what the effects of a possible mega-eruption would actually be. . Y The answer is that humanity would not perish even in this scenario.

“The result of such an explosion would not be pleasant, of course, but we would not be extinct. How do we know this? Because this super-explosion situation has already happened, and also on two occasions,” the Observatory website points out.

Scientists at this center explain that the last eruption of the volcano occurred 631,000 years ago and was ten times larger than the giant Tambora (Indonesia) eruption in 1815, and perhaps 100 times larger than the Pinatubo (Philippines) eruption in 1991. Therefore, its destructive capacity is undeniable.

Again, There were larger explosions than on Earth while humanity already existed, and yet it did not go extinct.. These events were Toba (Indonesia) about 74,000 years ago and Taupo (New Zealand) about 26,500 years ago.

Evidence provided by archeology shows that humanity was not in danger from the effects of the Toba explosion. For example, studies of hominin regions (although not necessarily homo sapiens), showing little change in activity before and after the eruption, protected by a widespread ash layer in South Asia.

However, as a result of the largest Toba eruption ever recorded in a volcano, there have been significant changes in living conditions and ecosystems.
