Buildings will collapse and tens of millions will die: what happens if the Yellowstone volcano erupts

Just one of several supervolcanoes in the world, it has survived three eruptions in the previous three million years. The latter happened 630 years ago and was 000 times larger than the eruption of Mount St. Helens in 1000 - an event that caused more than $ 1980 billion in damage. During the last eruption of Yellowstone, due to the large volume of the ejected mass, the earth collapsed and formed the depression, now known as the caldera, measuring 1 km by 55 km. What will happen during the next eruption, said the publication Express.

The next eruption is predicted to be disastrous for the entire world. They were attempted to be analyzed in the short documentary What If "What if the Yellowstone volcano erupts tomorrow?"

The narrator noted: “Right now, one of the largest volcanoes in the world is about to explode in the United States. If Yellowstone decides to erupt, the results will be disastrous. It has erupted three times over the past three million years, which has led some people to wonder if we should worry about another eruption in the near future. But if the eruption happened tomorrow, and you lived in North America, you would be practically unable to do anything. "

In geological and volcanic terms, "near future" can mean hundreds of thousands of years.

However, the documentary examined the potential for lava outflow and noted that Yellowstone is likely to produce few lava flows.

This is because before the mass turns into lava, it is in a state called magma.

Most of Yellowstone's magma will not turn into lava, because the intensity of the eruption will cause most of it to fly into the sky.

It will turn into airborne ash particles - small, incandescent lumps.

This alone will affect, to one degree or another, the entire United States and Canada. Tens of millions of people within a 1000 km radius will die.

When ash is inhaled, a cement-like mixture forms in the lungs, causing suffocation.

Meanwhile, the buildings will collapse - only 30 cm of ash is enough to collapse the roofs.

Experts suggest that even if you find yourself outside the 1000 km range, you will still have problems, since even on the east coast of the United States, about a centimeter of ash can fall - that amount is still dangerous to human lungs.

Some of the ash will travel to Europe, while the rest of the world will experience extreme weather changes.

The global temperature will drop by about 10 ° C, and this could last for almost ten years.

Ashes will affect crops as well as water supplies - practically everything else that our livelihoods depend on.

Organizations like NASA are working to prevent such a devastating event.

One of the possibilities explored is to increase the amount of water in Yellowstone. This will facilitate daily heat dissipation, which will minimize the risk of an eruption.

But from a practical point of view, convincing politicians to authorize such an initiative is most likely impossible.

However, NASA has another plan to drill a 10-kilometer well in Yellowstone and inject high-pressure water into it.

This will circulate the water and return it at a design temperature of 350 ° C, which will gradually extract heat from the volcano from day to day.

It is estimated that such a project will cost about $ 3,46 billion, but it will produce electricity at competitive prices, which means it has tempting benefits that can convince politicians to make the investment.
