Scientists have analyzed the noise before the eruption of the volcano

July 15, 2013. Redoubt Volcano in Alaska before the eruption has issued an unusually high-pitched sound that arose due to fluctuations in the Earth's crust in a series of small earthquakes preceding the eruption, according to a paper published in the journal Nature Geoscience.

Volcanic eruption is often preceded by the slack of the earthquake. They can go after each other with such a small gap, that the earth's crust, fluctuating, low-frequency issues "trill." Scientists led by a graduate of the Moscow State University of Geodesy and Cartography Ksenia Dmitrieva from Stanford University (USA) analyzed the eruption of Redoubt volcano

Geologists have announced the possibility of early prediction superizverzheniya

Supervolcano eruption, including the plural, as in this picture, can dramatically change the landscape for tens of kilometers and affect the climate of the entire planet (illustration from bbc.co.uk). In the case of powerful eruptions clear signs of impending disaster usually occur relatively shortly before the event. But scientists have found that binge supervolcano brewing, so far only in theory, can be computed in a few decades before the explosion.

Researchers from France, Switzerland and Singapore have studied images of rocks from the Greek island of Tyre, where three and a half thousand years ago there was a
