Is it necessary to be afraid of Vesuvia?

Italians look toward Vesuvius with conflicting feeling. On the one hand, it is one of the main national attractions, and on the other – the source of danger. Volcano, 20 centuries ago Buried Pompeii and Herculane, sometimes reminds of her formidable force. And scientists have no consensus when he can wake up.

Professor Geochemistry University of Napleto Benedetto de Vivo is convinced that after the abundant outpour of Lava 60 years ago Vesuvius calmed down for centuries. New rapid manifestation of him "feelings" It should be expected no earlier than 3000 years.

In confirmation, the professor leads the following calculations: on the place where the cone of Vesuvius rises today, the first eruption of magmatic rocks occurred 25 thousand years ago. Then, for 9 thousand years, Lava, ashes, hot gases, vapors of water and rock fragments have been thrown out of the earthly decrees. 14th thousand years ago there was a calm, lasts four thousand years.

The second cycle of activity falls for the period from 8,000 to 2500 years ago. Passed another 700 years – and hit the 79th year of Christ, when Pompeii and Herkulan died. But soon the mountain was covered with vegetation, her slopes were populated by animals, and the descendants of the ancient Greeks and Latinians lived at her foot "neighbor". The next period of physiological peace of the Black Mountain came, interrupted only in 1631, when a strong eruption took the lives of thousands of people, and in 1944, coincided with the landing of the Allied troops in Italy under the curtain of World War II.

It is known that the sea of ​​hot lava area of ​​about 400 square kilometers "Plechen" At an 8-kilometer depth under the southern tip of the Apennine and the tormenting to the surface. But de vivo believes that two "Valves", Sycilian Etna and Strombol Volcano on the Island in the Tyrrhenian Sea are served by the excess pressure while. Mavel Vesuvia will inevitably precede the increase in seismic activity caused by the movement of magmatic rocks towards the surface of the Earth, changing the chemical composition of gases in fumarols, violations of the gravitational field. In the meantime, near Naples, nothing like this is noticed.

Nevertheless, the authorities are not discarding the forecasts of pessimist, stages of emergency evacuation plan developed in 1995. It provides for the improvement of the transport network, laying wider roads on the slopes, renewal of water supply systems, power lines. And the main thing – in the headquarters of the civil defense service, the routes of organized retreat are practiced: from the volcano to the saving sea.

Is it necessary to be afraid of Vesuvia

Giovanni Machedonio, director of the observatory, leading around the clock observation of the most famous volcano in the world, far from benevolent. Vesuvius did not fall asleep for hundreds of years, he believes, but only for a while. "This is an active volcano. If he wakes up, then – explosionless, and not a simple outline of lava", — Warns scientist. He made a report on readings in Rome dedicated to the 60th anniversary of the last eruption of Vesuvius. Then he drove the fiery lava 11 days, under which 26 people died and 12 thousand were left without a bed. "Currently there are no signs of imminent activity of Vesuviya", — the scientist agrees, but the vigilance to lose in no case can.

Separate volcanologists warn and that it is impossible to predict neither the place of appearance nor the direction of the lava flows. In June 2003, local authorities have allocated 724 million euros to implement the voluntary departure plan of 150 thousand inhabitants from Vesuvia. Each family living there is promised even "Premium" 30 thousand for arrangement in other areas.

At the same time, local authorities stated that they do not intend to turn "Red zone" In lifeless space. "Vesuvius is our friend, our profits source. We must learn to respect its natural temper and ensure the safety of people", — explained to journalists the governor of the campaign area with the administrative center in Naples. View 4 million pilgrims from all over the planet annually arrive at Vesuvius every year.
