The highest and most active ethna volcano in Europe today began eruption, raising a huge ash pillar in the sky, and the authorities closed the airport of Catania on the east coast of Sicily.
About 130 small seismic oscillations occurred during an eruption and after eruption, from 11:00 on Minsk time. According to the National Institute of Geophysics and Volcanology Italy, the maximum strength of the jigsage was 4 points on the Richter scale.
According to the information received, the height of emissions produced by the volcano reaches more than 500 meters, the smoke rose to 3 km, and the lava spread area exceeds many thousands of square meters. It should be noted that approximately once every 150 years, the eruption destroys any village located on a dangerous approximation to the foot of Etné, but the persistent Sicilians do not stop this fact, and they fearlessly continue to populate the volcano slopes.
There are currently no information about the victims. The last major eruption of the 3330-meter volcano occurred in 1992.
It should be noted that, despite the existing danger of harmfulness and health of residents living in close proximity to the volcano, representatives of the Italian authorities decided not to hurry with evacuation and so far only warned Sicilians that they should be alert.
Scientists from the Open University (Great Britain) found out that the ethna volcano on Sicily was not filled with magma: it reduces the likelihood of a serious eruption, but strongly increases the risk of collaps.
Etna "moves" in the sea with high speeds for such processes in several centimeters per year. Previously, scientists thought that the movement was caused by the pressure of the magma in the barrel of the volcano (on average every 3-5 months from one of the numerous crater ethna eves the lava). But the last observations argue that the wines of the entire gravitational forces that affect the sole of the volcano at a distance of 12 kilometers from the coast and a depth of 1.2 kilometers, the Europouls marks.
To collect data, research unmanned submarines from April 2016 to July 2017 regularly sent to the volcanic sole. The data collected by them showed that the movements ethn are not similar to those that can cause tectonic activity. For example, scientists spotted an eight day when the volcanic sole was shifted by 4 centimeters, but there were no underground jolts.
This proves that the volcano gradually loses the activity and the likelihood of large eruptions is reduced. But the inhabitants of Sicille are too early to rejoice: Most likely, the collaps are poisoned, and they will be stronger than expected before. Despite the volcanic activity, people always settled on the slopes of Ethn; Now they will have to adapt to a new type of disaster.

In Italy, Two days ago, Vesuviy volcano woke up. In Naples, located next to the volcano, some areas. Residents of five urban areas and tourists had to literally flee. Among other things, the eruption led to forest fires on the slopes of the volcano.
Naples at night reminded the images of hell on the paintings of medieval artists.
Danger represents not only the burning forest, but also a volcano himself, capable of pouring the surroundings of a lava at any time or cover the large territory with a layer of hot ashes.

The picture is frightening also because in the spread of forest fires on the slopes of Vesuvia accused the mafia or pyrography. In some media, even appeared reports that the fire is distributed with the help of adjacent animals.
Organized crime, as stated, distributes the flames in the Vesuvius National Park to burn garbage on illegal landfills or prevent the construction of individual buildings in the area.
It is worth noting that while Vesuvius is not erupted, but smoke and fire around the volcano look like a real eruption.
The World Wildlife Foundation (WWF) issued a special statement that thousands of people, animals and the territory of the natural reserve around the volcano are in the risk area. "The situation is extremal, so it is necessary to take extraordinary measures," the WWF statement said.

In 79, our era, Vesuviya eruption destroyed three cities - Pompey, Herculaneum and Staby. The precursor of the eruption was the strong earthquake described in the "annals" of Tacitus and "letters" of Plinia Jr.. Pompeii city is now - an open-air museum.
In Italy, the eruption of the ethna volcano - the largest of the three existing in the country began. Evacuation in connection with the activity was not announced. In 2017, ten people suffered as a result of the eruption.
The eruption of the volcano began on the island of Sicily on Monday, December 24th. It was provoked by a small earthquake. The volcano thrown into the sky a huge column of ash and dust. But at the same time, the situation is not dangerous, all tourists are evacuated from the nearest zone.
Ethna volcanic eruption in Italy - consequences and victims
According to RIA-News, the seismologists registered more than 150 underground jokes in the zone of the famous volcano on the east coast of the Italian Island of Sicily, near the city of Catania. The most powerful of them from the magnitude of 4.0 occurred at 20:26 (22:26 Moscow time) on Monday. The epicenter of the earthquake was at a depth of about two kilometers, just seven kilometers from the Ralyna commune.
According to volcanologists, a new crack formed on the southeastern slope of the volcano, from which the black ashes cloud rose. Because of this, the authorities suspended the work of the Fontanarossa International Airport and the movement of trains along the route Messina to Syracuse.
In addition, volcanic ashes pounded many cities and villages in Catania, employees of public services quickly remove the streets and squares there.
According to experts, there are no reasons for concern, since this eruption does not pose a threat to anyone or for material objects.
Etna is the highest active volcano of Europe, in June 2013 he was listed as a UNESCO World Heritage Site.
The authorities closed the airport in Sicily
From the highest and most active volcano of Europe, the smoke and a huge number of ashes began to go out. Due to the eruptions, I had to forced to suspend the work of the airport of Catania.
There is no information about the victims yet. There is no information. Etna, which reaches 3 thousand 300 meters in height, can throw ashes, smoke and dust several times a year.
The last time the powerful eruption occurred in 1992.
Geologists assure that Etna's volcano is a big geyser
The famous Mount Etna in Sicily may be a giant geyser, not a volcano, which indicates an unusually large amount of steam and other volatile substances in its emissions, declares a scientist in an article published in the Earth-Science Reviews magazine.
"This volcano looks like the principles of his work on a giant geyser or, in a sense, on the exhaust pipe. A narrow system of "laurels" is the role of this pipe, through which millions of tons of hot water and gas rise to the surface of the Earth. If it is "clogged" with a relatively dense lava, then the gas emissions stop and the volcano "spits" this solid cork, and when she is cleaned, it throws mainly gas and steam, "writes Carmelo Ferlito from Catania University (Italy ).
Etna volcano is one of the most restless geological objects on Earth - it almost constantly hesitates Lava, couples and manifests other signs of activity, and Herlo is never standing in place and constantly changes its position. According to the current estimates of scientists, its position has changed at least three times over the past 40 years, and every year Etna spells several tens of millions of tons of lava.
Another unusual feature of the main mountain of Sicily is that it throws huge amounts of dust, steam and various volatile substances into the atmosphere, whose mass today is estimated at about 7 million tons. Most geologists believe that this is due to the special chemical composition of the magma in the depths of ethn, and the unusual device of its magmatic chamber.
Ferlito believes that there is a much simpler explanation and the other strange feature of Etna - in fact, this mountain is not a real volcano, but a huge hot source that pumps up millions of tons of water and other bat elements, most of whom leave The volcano is not through the zhero, but through numerous cracks on its slopes.
It was obscured by strangeness in the chemical composition of the lava and emissions of Etna. As the researcher notes, lava samples from the depths of the mountain contain approximately 3.5% water, which is a high, but not a record indicator. On the other hand, the volcano himself throws about 1.5 times more than water and other volatile substances than basalt and other solid rocks, which is about 10 times more than theoretical calculations show.
Accordingly, if you believe in such measurements, "Lava" ethna should consist of 70% of water, carbon dioxide, sulfur dioxide and other volatile substances in an intermediate state between liquid and gas, and only 30% of its mass falls on solid rocks.
Such an exotic composition of Lava, as a scientist notes, is not characteristic of any other volcano, and therefore he had to actually calculate how its behavior changes as it rises to the surface of the Earth. These calculations showed that Etna is actually a geyser, the clogging of which leads to the eruptions of basalts and other breeds.
When this lava rises to a mark of about 2-3 kilometers from the surface of the Earth, the mixture of rocks and volatile substances is sharply divided and the gas rushes into the atmosphere, moving through the cracks and the main thing in Etna. Heavy breeds begin to accumulate inside the "laurels" and after a while they block the movement of the gas, which leads to a sharp increase in pressure in the depths of the volcano.
At a certain point in time, the gas "embroodbles" these stone stoppers and pushes the lava to the surface, causing explosively eruptions that often occur on Etna. Similarly, according to Ferlito, it is possible to explain the high level of activity of the main volcano of Sicily, and the unusual composition of its emissions.
