Today on the Earth's surface is about 600 active volcanoes and up to 1,000 extinct. In addition, under water, they are hiding approximately 10 thousand. Most of them are located at the junctions of tectonic plates. About 100 volcanoes are concentrated around Indonesia, in the Western us States, there are about 10, the cluster of volcanoes also noted in the area of Japan, the Kuril Islands and Kamchatka. But they are nothing compared to the one megavolcano, which scientists fear most.

the world's most dangerous volcano

The Most dangerous volcanoes

The particular danger is any of the existing volcanoes, even extinct. To determine which of them is most dangerous, not taken nor a volcanologist or geomorphologist, since it is impossible to accurately predict the time and power of the eruption of any of them. The title of “the world's most dangerous volcano” at the same time expect the Roman Vesuvius and Etna, Popocatepetl Mexican, Japanese Sakurajima, Galeras Columbia, located in Nyiragongo, Congo, in Guatemala – Santa Maria in Hawaii-Manua Loa and other.

If the danger of the volcano to assess the alleged damage that he can inflict, it is reasonable to turn to history, describing what the consequences brought the most dangerous volcanoes in the world in the past. For example, the well-known mount Vesuvius blew in 79 ad to 10 thousand of lives and wiped off the face of the Earth two major cities. The eruption of Krakatoa in 1883, which power of 200 thousand times greater than the atomic bomb dropped on Hiroshima, echoed throughout the Land and took the life of 36 thousand inhabitants.

the most dangerous active volcanoes of the world

The next year because Lucky was bad for all of Europe. All this shows how large-scale consequences can result for people of the eruption of a large volcano.

Devastating supervolcanoes

But did you know that all the biggest threat volcanoes in the world are nothing compared to so-called supervolcanoes, the eruption of each of which thousands of years ago brought disastrous consequences for the whole Earth and changed the climate of the planet? The eruption of these volcanoes could have a force with 8 points, and the ash amount of not less than 1000 m3 were thrown to a height of not less than 25 km away. This led to prolonged sulfur precipitation, lack of sunlight for months and cover huge layers of ash a large area of the earth's surface.

what is the most dangerous volcano in the world

The Supervolcanoes are characterized in that at the eruption site they have not the crater, and Caldera. This cascabraga basin with a relatively flat bottom is formed as a result of the fact that after a series of strong explosions with emission of smoke, ash and magma of the upper part of the mountain collapses.

The Most dangerous volcano

Scientists know about the existence of about 20 volcanoes. One of these frightening giants is today lake Taupo in New Zealand, another SUPERVOLCANO hidden beneath lake Toba, on the island of Sumatra. Examples of supervolcanoes are also of long valley in California, vellis in new Mexico and Aira In Japan.

But the world's most dangerous volcano – is the most “ripe” to the eruption of the Yellowstone SUPERVOLCANO, located in the Western us States. It makes volcanologists and geomorphologists United States, and around the world, to live in a state of growing fear, forcing to forget about all of the most dangerous active volcanoes in the world.

Location and size of the Yellowstone

Yellowstone Caldera is located in the North-West of the USA, in Wyoming. She was first sighted by satellite in the 1960's. Caldera, whose dimensions are approximately 55*72 km, is part of the world-famous Yellowstone national Park. A third of the nearly 900,000 hectares of parkland located within the Caldera of the volcano.

Under the crater of the Yellowstone to this day lies a giant bubble of magma to a depth of about 8 000 m. temperature of the magma inside it is nearing 10000C. Due to this on the territory of Yellowstone Park's boiling hot springs, from cracks in the earth's crust raised a cloud of steam and gas mixtures.

Also there is a lot of geysers and mud pots. The reason for this was heated to a temperature of 16000 With a vertical flow of solid rock with a width of 660 km Under the Park at a depth of 8-16 km there are two branches of this stream.

Eruption of Yellowstone in the past

The First eruption of Yellowstone occurred, according to scientists, more than 2 million years ago, it was the biggest disaster on Earth in the entire history of its existence. Then, by assumption, volcanologists were released into the atmosphere about 2.5 thousand km3 Of rock, and the high watermark that they achieve these emissions amounted to 50 km above the earth's surface.

The largest and Most dangerous volcano in the world started re-eruption more than 1.2 million years ago. Then the emissions were approximately 10 times less. The third eruption was 640 thousand years ago. Itthen fell the walls of the crater and formed the current Caldera.

Why does today have to be afraid of the Yellowstone Caldera

In light of recent changes at Yellowstone national Park scientists is becoming clearer what the most dangerous volcano in the world. What happens there? Scientists alarmed by the following changes, which are particularly intensified in the 2000s years:

  • For 6 years prior to 2013, the earth covering the Caldera rose by as much as 2 meters, whereas for the previous 20 years the rise was only 10 cm
  • From the ground scored a new hot geysers.
  • Increasing the frequency and strength of earthquakes around the Yellowstone Caldera. In 2014, scientists have recorded about 2000.
  • In some places through the layers of the earth's surface make their way underground gases.
  • A few degrees increased temperature of the water in the rivers.

These scary news alarmed the public, and especially the inhabitants of the North American continent. Many scientists agree that a SUPERVOLCANO eruption will occur in this century.

The consequences of the eruption for America

No wonder many volcanologists believe that the Yellowstone Caldera-the world's most dangerous volcano. They assume that the next eruption will be as powerful as the previous one. Scientists liken it to an explosion of thousands of nuclear bombs. This means that within a radius of 160 km around the epicenter will be totally destroyed. In “dead zone” will become covered with ash, the territory, stretching for 1,600 km around.

The Eruption of Yellowstone may lead to eruptions of other volcanoes and the formation of a powerful tsunami. For US an emergency occurs, and will be introduced martial law. From various sources there are reports that America is preparing for disaster: building shelter, produces more than a million plastic coffins, is the evacuation plan, making agreements with countries on other continents. Lately about the true state of Affairs at the Yellowstone Caldera, the United States prefers to keep silent.

The Yellowstone Caldera and the end of the world

The Eruption of the Caldera, located under Yellowstone Park, it will bring trouble not only to America. The picture that can be deployed in this case, seems sad for the world. Scientists estimate that if emissions to a height of 50 km will last only two days, “the cloud of death” during this time, will cover the territory twice as large as the entire American continent.

A week later, the emissions reached India and Australia. The sun's rays sink into the thick volcanic smoke and will come to Earth a long year and a half (at least) winter. The average temperature on Earth will drop to -250, and in some places reaching as high as -50O. People will die under falling debris from the scorching lava, from cold, hunger, thirst and the inability to breathe. According to assumptions, will survive only one person out of a thousand.

the most dangerous volcanoes in the world

The Eruption of the Caldera of the Yellowstone if you are not able to destroy life on earth completely, radically change the conditions of existence of all living things. No one can say for sure, whether its this eruption of the world's most dangerous volcano in our lifetime, but the fears are really justified.
