Uturunku eruption may lead to the climatic and demographic catastrophe.
In South America, suddenly awakened volcano Uturunku. It is located in southwest Bolivia, and reaches a height of six thousand feet. Scientists fear that it is growing at an incredible pace, accumulating magma is ten times faster than conventional volcanoes. If this growth will cause the supervolcano, then most of its eruption lead to climatic and demographic Disasters. It will be a terrible paralyzed flights in Europe in the spring of 2010, when Iceland's Eyjafjallajokull erupted.
"This is one of the areas with the greatest volcanic activity on Earth. And important time to understand what it may bring, so you should find out the reasons for this rapid growth," — said Professor Shan de Silva of the University of Oregon.
Uturunku is classified as a stratovolcano. This is the most common type, they erupt periodically, and may not yield loss as a thick lava cools rapidly and does not extend far. For example, Avacha Volcano, located to the north of Petropavlovsk-Kamchatsky, is a stratovolcano, and because their security is an excellent material for the study.
If, however, the rapid accumulation of magma lead to the transformation in Uturunku supervolcano, the consequences would be devastating to the eruption. Ash and sulfur gases emissions can reach the stratosphere and, like a blanket, cover the globe. Then the sun will no longer penetrate into the atmosphere, leading to a decrease in temperature. Gases are converted into sulfuric acid, which will fall to Earth along with precipitation. A similar effect can cause a hypothetical nuclear winter.
When 73 thousand years ago, a volcanic eruption on the island of Sumatra has caused enormous demographic crisis. Sulphurous rain lasted for six years, and the ashen cloud almost completely hid the sun. On Earth, survived only ten thousand people.
Severe consequences for the entire population of the planet was a Peruvian volcano eruption Uaynaputina in 1600. Disaster has come to Russia in 1601 — 1603 years., When he was a terrible famine and crop failure, in which three million people died. And when, in 1815 pulled supervolcano Tambora in Indonesia, the temperature dropped to 2.5 degrees and remained at the same level throughout the year. Frosts burst in the middle of the summer, so in 1816 known as the "year without a summer."
In our time, the danger of "volcanic winter" comes in the first place, from Yellowstone Park, where the famous geysers. Under these remarkable sources is a time bomb. Over the last million years eruption occurred only twice. So, an hour, when it detonates, inevitably approaching.
It is not clear what effect the eruption Uturunku. Last Lava occurred in this region 300 thousand years ago.
