Supervolcano threatens America


25.01.11.Sudya are signs that the gigantic dormant volcano beneath Yellowstone National Park in Wyoming, USA, in the years to wake up — the first time in the last 600 thousand years, the newspaper Daily Mail. If this happens, the consequences for America and the world could be catastrophic.

The red-hot magma beneath the surface of the giant caldera — the crater of the volcano, which occupies more than half of the national park — began to rise in 1928. However, in recent years, scientists have noticed a dramatic increase in the speed of the lift: it could mean that the volcano is preparing to erupt. "While the magma at a depth of about 10 km, and to sound the alarm early. But if it rises to the level of 2-3 km, we have a serious cause for concern, "- says Robert Smith (Bob Smith), a professor of geophysics at the University of Utah.

Scientists have still not enough data to judge whether the eruption. But if it does happen, the consequences can be catastrophic. Volcanic ash fall within 1,000 miles (over 1,600 km) around a thickness of 10 feet (3 meters), making? the U.S. uninhabitable. Millions of people in this case would have to leave their homes and flights in North America due to a giant ash cloud will be permanently paralyzed. Of course, such a massive catastrophe will not affect the life of the planet.

The awakening giant Yellowstone will be many times bigger than the eruption of the Icelandic volcano Eyjafjallajökull last spring. Recall Eyjafjallajokull erupted twice on March 20 and April 14. Scientists say that the second eruption was 10-20 times more powerful than the first. The resulting cloud of volcanic ash is not only fully closed movement in Europe in the air, but also brought a lot of problems on the ground, for example, Icelandic farmers had to quickly build a shelter for their animals, the health and even lives are threatened by the same ashes.
