The largest volcano has awakened. When the Yellowstone volcano erupts

Scientists warn of an imminent cataclysm, which will be the largest in the history of human development. How will the eruption affect Russia, will the country face a catastrophe?

According to research by specialists from the University of Arizona, in less than a hundred years, a supervolcano will erupt in Yellowstone. Yellowstone volcano is a huge depression with a diameter of 80 by 40 km, formed as a result of several super-eruptions over millions of years. The last time the volcano erupted lava was 640 thousand years ago, and it is possible that we will soon witness this event.

What will happen to humanity?

According to experts from the US Geological Survey, the consequences of a volcanic eruption will be comparable to a nuclear explosion. As a result of the release of hot magma to a height of 50 kilometers, the entire western American coast will be a dead zone covered with a one and a half meter layer of ash. Nothing alive will remain within a radius of 500 km, and 90% of people and nature will die 1200 kilometers from the eruption point.

According to estimates, about one hundred thousand people will become victims of asphyxiation and hydrogen sulfide poisoning. In a day, acid rain will fall in the United States, from which all vegetation will die. And in a month, the Earth will plunge into darkness, as the Sun will hide behind clouds of ash and cinders.

The climate will change dramatically, there will be a sharp cooling of 10-20 degrees. Because of this, oil and gas pipelines, railways will fail. The ozone hole will grow, killing the remaining living organisms. Because of the awakened volcano in Yellowstone, lava and other volcanoes will begin to erupt. Because of this, many tsunamis will arise, washing away the cities in their path.

Which countries will be affected the most?

Not only the United States will suffer, but most countries. Most of all will get to China, India, the Scandinavian countries and the north of Russia. Life will stop there. The number of victims in the first year of the global catastrophe will reach two billion people. Southern Siberia will suffer the least. The period, which scientists have already called "volcanic winter", will last four years. And humanity will have to cope with the consequences for a very long time. Over the next century, the Earth will return to the Middle Ages again, plunged into savagery and chaos.

Can the Earth be saved?

The only consolation is that many serious scientists reject such a scenario and doubt that such an apocalypse is possible not only in the near future, but ever. According to Aleksey Sobisevich, head of the laboratory at the Institute of Physics of the Earth, Russian Academy of Sciences, a volcanic eruption in Yellowstone is possible not earlier than in hundreds of thousands of years. And, in the end, it is not so scary, because our distant ancestors managed to survive three such super-eruptions. At the same time, scientists do not exclude that the supervolcano can wake up with the help of earthlings themselves.

The attack on the volcano is one of the methods of terror, which can become the most dangerous. The volcano can be detonated artificially by blowing up the lid of the magma chamber using megaton-class warheads.

The most pessimistic scenario for the awakening of a supervolcano is as follows: it will be an explosion comparable to the explosion of 1000 atomic bombs. The ground part of the supervolcano will collapse into a funnel with a diameter of fifty kilometers. An ecological catastrophe will occur on Earth. For the US, the eruption of Yellowstone will mean the end of existence.

The saddest thing is that not only alarmists, but also experts are talking about such consequences. Yakov Levenshtern from the Yellowstone Volcanic Observatory (USA) said that more than 1 thousand km³ of magma fell out into all previous supervolcano eruptions (there were three of them). This is enough to cover most of North America with a layer of ash up to 30 cm (at the epicenter of the disaster). Loewenstern also noted that the air temperature throughout the Earth will drop by 21 degrees, visibility will become no more than half a meter for several years. An era similar to nuclear winter will come.

Hurricane Katrina showed that the US civil defense system is not ready for such large-scale cataclysms - and the civil defense of no country will be able to prepare for them.

Domestic scientists do not get tired of predicting the eruption of a supervolcano. The head of the Department of Dynamic Geology of the Geological Faculty of Moscow State University, Nikolai Koronovsky, in an interview with Vesti, told what would happen after the eruption:

“The winds are predominantly westerly, so everything will go to the east of the USA. Will cover them. Solar radiation will decrease, which means that the temperature will have to fall. The well-known eruption of the Krakatau volcano in the Sunda Strait in 1873 lowered the temperature by about 2 degrees in the equatorial part for a year and a half, until the ash dissipated.

Many volcanologists have started talking about the fact that the Yellowstone volcano is waking up and its eruption can begin at any moment! What then will become of the United States and the rest of the world if this suddenly happens?

According to American volcanologists, the eruption of the largest volcano in the world, the Yellowstone Caldera, can lead to the Apocalypse.

Recently, the dormant volcano has begun to show more and more obvious signs of activity, which only further inflames the situation around it.

Why is there black smoke coming out of the Yellowstone volcano geyser?

So, very recently, on the night of October 3-4, 2017, black smoke poured out of the volcano, which seriously frightened the inhabitants of Wyoming. It turned out that the smoke was coming from Geyser "Old Faithful"- the most famous geyser volcano.

Usually, a volcano ejects jets of hot water from a geyser as high as a 9-story building at intervals of 45 to 125 minutes, but here instead of water or at least steam, black smoke poured out.

Why is black smoke coming out of a volcano?- unclear. Perhaps this is a burning organic matter that has approached the surface.

What happens if the Yellowstone Super Volcano erupts?

The first known eruption was two million years ago, the second was 1.3 million years ago, and the last earthquake occurred 630,000 years ago.

A super-volcano under Yellowstone National Park has been growing at a record rate since 2004. And it can explode with a force a thousand times more powerful than several hundred volcanoes all over the earth at the same time.

At any moment, with its eruption, it can destroy the territory of the United States, which may even begin a world catastrophe - the Apocalypse, as some American scientists believe.

Experts predict that the volcanic eruption will be no less powerful than all three times when the Yellowstone volcano erupted over the past 2.1 million years.

According to forecasts of volcanologists, lava will rise high into the sky, ash will cover nearby areas with a layer of 15 meters and a distance of 5000 kilometers.

In the very first days, the territory of the United States may become uninhabited due to toxic air. The dangers in North America will not end there, as the likelihood of earthquakes and tsunamis that can destroy hundreds of cities will increase.

The consequences of the explosion will affect the whole world, as the accumulation of vapors from the Yellowstone volcano will envelop the entire planet. The smoke will make it difficult for the sun's rays to pass through, which will provoke the onset of a long winter. Global temperatures will drop to -25 degrees on average.

Experts believe that the country is unlikely to be affected by the explosion itself, but the consequences will affect the entire remaining population, as there will be an acute shortage of oxygen, perhaps due to a decrease in temperature, first plants and then animals will not remain.

For example, before the earthquake, many pet owners noticed that the animals behaved extremely strangely: dogs barked incessantly, cats rushed around the house, etc.

As for Yellowstone, even there the animals behave strangely. As the news of the possibility of a super-volcano eruption became more and more alarming, videos of bison escaping from Yellowstone National Park appeared on the Web. This caused concern already among people who decided that such behavior could be a sign of an imminent eruption of a super-volcano.

And although experts assure that these are just seasonal migrations of animals in search of food, the public still does not believe in such coincidences.

An analysis of the molten rock of the Yellowstone super-volcano showed that an eruption is possible without any external influences, so a catastrophe can occur at any time. Well, if asteroids fall into the territory of the United States, then the end of the world certainly cannot be avoided. By the way, about the nearest dates of the approach of dangerous asteroids, read and watch the video in THIS ISSUE!

Hurricane Katrina showed that the US civil defense system is not ready for such large-scale cataclysms - and the civil defense of no country will be able to prepare for them.

There is a powerful and terrifying threat lurking beneath Northwest Wyoming and Southeast Montana that has been changing the landscape over the past few million years and is known as the Yellowstone Supervolcano. Numerous geysers, bubbling mud pots, hot springs, and evidence of long-standing eruptions make Yellowstone National Park a fascinating geological wonderland.

The official name for this region is the "Yellowstone Caldera" and it covers an area of about 72 by 55 kilometers (35 by 44 miles) in the Rocky Mountains. The caldera has been geologically active for 2.1 million years, periodically ejecting lava, clouds of gas and dust, reshaping the landscape hundreds of kilometers around.

The Yellowstone Caldera is one of the largest in the world. The caldera, supervolcano, and underlying magma chamber help geologists understand volcanism, and serve as an important site for studying the influence of hotspot geology on the Earth's surface.

History and migration of the Yellowstone Caldera

The Yellowstone caldera actually serves as an "exit" for a plume (hot mantle flow) extending hundreds of kilometers down through the earth's crust. The mantle plume persists for at least 18 million years and is a region where molten rock from the Earth's mantle rises to the surface. It remains relatively stable as the N American continent passes over it. Geologists track a series of calderas created by a mantle plume. These calderas move from east to northeast. Yellowstone Park is located right in the middle of the modern caldera.

The caldera experienced "super-eruptions" 2.1 and 1.3 million years ago, and then again about 630,000 years ago. Super eruptions are massive, spreading clouds of ash and rock over thousands of square kilometers around. Compared to "super eruptions," smaller eruptions and Yellowstone hotspot activity are relatively minor today.

Yellowstone Magma Chamber

The mantle plume that feeds the Yellowstone Caldera passes through a magma chamber about 80 kilometers long and 20 kilometers wide. It is filled with molten rock, which is currently relatively calm under the Earth's surface, although from time to time the movement of lava inside the chamber causes earthquakes.

The heat from the mantle plume creates geysers (shooting hot water into the air from below the earth's surface), hot springs and mud pots scattered all over the place. Heat and pressure from the magma chamber are slowly increasing the height of the Yellowstone Plateau, which has been growing at a faster rate in recent times. However, there are no signs yet that a powerful volcanic eruption will occur.

Of even greater concern to scientists studying the region is the danger of hydrothermal explosions between major super-eruptions. These outbreaks occur when underground hot water systems are disrupted by earthquakes. Even earthquakes at a great distance can affect the magma chamber.

Will the Yellowstone volcano erupt in 2018?

Sensational stories suggesting that the devastating eruption of the Yellowstone volcano is about to occur occur every few years. Based on detailed observations of earthquakes that occur locally, geologists are confident that the volcano will erupt again, but probably not anytime soon. The area has been relatively inactive for the last 70,000 years and is expected to remain quiet for thousands of years to come.

According to the US Geological Survey, the odds of the Yellowstone supervolcano erupting during this year are 1 in 730,000. Here's a little comparison: it's more likely than your chances of winning the lottery big, and only slightly lower than your chances of being hit lightning.

But practically no one has any doubts that sooner or later it will be strong again, and this will be a catastrophe on a planetary scale.

Consequences from the super-eruption of the Yellowstone volcano

In the park itself, lava flows from one or more volcanic sites are likely to cover most of the local landscape, but the biggest danger is a cloud of volcanic ash that will spread hundreds of kilometers. The wind will carry the ash up to 800 kilometers, eventually covering the middle of the United States with layers of ash and destroying the Central region of the country. Other states will be able to see the volcanic cloud, depending on their proximity to the eruption.

While it is unlikely that all life on Earth will be completely wiped out, it will definitely be affected by ash clouds and mass ejecta. On a planet where the climate is already changing so rapidly, additional emissions are likely to change the growth rate and growing seasons of plants, leading to a reduction in food sources for all life.

The USGS keeps a close eye on the Yellowstone Caldera. Earthquakes, small hydrothermal events, even a slight change in the eruptions of old geysers, give clues to changes deep below the Earth's surface. If magma starts moving in ways that indicate an eruption, the Yellowstone Volcanic Observatory will be the first to alert nearby areas.
