A photo from open sources, America, they scare us, will perish first. But also the whole planet will have to be tight. From the clatter of hooves dust in the reserve flies. The other day, the online community flinched. And after him they got scared and viewers who were shown videos about how animals leave Yellowstone National Park – a vast territory, located in the northwestern United States. The bison ran specifically pounded hooves right on the highway. What are citizens aware of the ability of the smaller brothers to respond to the approaching natural cataclysms, concluded that they – bison – are saved, sensing trouble. Which one? Of course, the swift and powerful eruption of Yellowstone super volcano, which is located here. They scare them already year, predicting almost the end of the world.
And as if to reinforce fears, the reserve began shake tremors. Earthquake that occurred in early April, became the largest in the last quarter century. IN water was heated in local reservoirs …
Reassuring compatriots, head of national press service El Nash Park assured that from the current seismic activity there is no harm to the reserve. As for the bison, it’s not they run headlong, and migrate the most common for themselves way.
– We really see the outcome of bison, moose and others animals outside the national park, said Nash. – But they do this because they are sent to the lower sections of the slopes, where it’s easier to find food now. When the snow comes down and fresh greens appear, the same animals will come back.
A little earlier, however, an employee of the press service Amy Bartlett she assured that the animals did not run away from the park at all, but into the park.
Discrepancies only raised doubts. And they added fear. Especially that there really is reason for concern.
Monstrous vent
The Yellowstone Super Volcano, aka the Yellowstone Caldera, huge. Just monstrous. Studies show that the “monster” alive and gaining power. And, therefore, capable of it sooner or later arrange a global cataclysm.
Professor Robert Smith and Professor Mikhail Zhdanov from the University Utah, following the propagation of seismic waves from numerous earthquakes, determined the real size Yellowstone Caldera. They saw what’s inside.
There is a sea of molten rock. Red-hot magma reaches for 240 kilometers in one direction and almost 700 in the other direction.
By measuring the electrical conductivity of the bowels, scientists specified three-dimensional picture. It turned out that magma does not go so deep cool, as previously thought: at an angle of less than 40 degrees, not 60. Its layer with a thickness of more than 100 kilometers is quite close to the surface, covering a huge area. If start eruption, then all of it will become a vent.
Mount St. Helens – active, can be connected to the caldera a volcano located in the western United States 88 kilometers from Portland – the main city of Oregon. According to sounding, which conducted by Graham Hill of the New Zealand Institute of Earth and Nuclear research, and under Mount St. Helens are huge cavities molten rock that stretch one way at 50 kilometers, to another – by 70. With a relatively narrow channel, which Now it goes from the bowels to the volcano, several more are connected. And rather In total, the system extends to the Yellowstone Caldera.
The worst case scenario is the eruption of the entire system at once, to which can connect volcanoes in other places. But similar disasters, fortunately, they happen infrequently.
– It seems that a disaster of this kind once occurred on Mars, where the largest volcano in the solar system is now located “Olympus Mons,” Hill says. – The height of this monster is 27 kilometers – three times more than that of Everest. Diameter – 550 kilometers.
A little further three more impressive Martian volcanoes – Arsia Mons, Pavonis Mons and Ascraeus Mons, which are likely to connected to a single system. Starting to erupt synchronously, they are quite could greatly harm the planet. Until destruction on her of life.

BTW
Time is running out
If you believe volcanologists, then “the phenomenon of nature is catastrophic character affecting the life of the entire planet “- namely global eruptions – happened regularly: 4, 10, 15, 22, 30, 34, 40, 45, 49, 60 and 65 million years ago. That is, approximately every 5 million years. In one of the cataclysms, dinosaurs fell completed their era 65 million years ago.
According to some estimates, those same 5 million years of “respite” or already passed, or about to pass. Maybe x-hour will come in a year or two.
There is a version according to which about 200 million years ago volcanoes end the world for most archosaurs – dinosaur predecessors. Then the lava flooded huge space in the territory of present Siberia and India.
Together with archosaurs, more than 60 percent disappeared from Earth plants.
Scientists do not yet know the causes of synchronous eruptions. That is, and they cannot predict. But the fact that danger exists is not exclude.
The Yellowstone Super Volcano erupted at intervals of approximately in 700 thousand years. And they end. Here is such a bad coincidence…
INSTEAD OF COMMENT
There is no life without eruptions
– On a synchronous eruption in the current overpopulated world is better don’t think at all, says a volcanologist, Ph.D. Konstantin Grigoryev. – It will happen, it will happen. But not the fact that in the next million years. A smaller disaster full end light does not threaten. They are even useful globally. Because the regulate habitat conditions. And most importantly, the temperature.
The whole point, according to geochemists, is in the carbon dioxide cycle, from which the greenhouse effect arises and the atmosphere heats up. It seems that in billions of years it should have accumulated as much as you can get burned. However, they did not get burned. Because the showers, hurricanes turn it into liquid carbon dioxide. It reacts with minerals, forms limestones that are washed off into the oceans and deposited on the bottom. Thus, carbon dioxide is removed from the atmosphere. Next for due to the movement of tectonic plates, sedimentary rocks penetrate bowels where they melt.
Carbon dioxide is released and is again “injected” into atmosphere during volcanic eruptions. Tsunamis are also worthwhile. The waves ashore mineral particles that improve the soil, fertile deposits accumulated in large areas are eroded over large areas riverbeds. If volcanoes stop adding to the atmosphere carbon dioxide, then the Earth will turn into a frozen snowball. A if tsunamis and floods cease, the soil will become poorer.
But what about people? The main thing is not to overdo it in terms of saturation carbon dioxide atmosphere. Otherwise, the planet will begin remove carbon dioxide from the atmosphere more intensively. And it threatens an increase in the number and power of hurricanes, floods and earthquakes.
