The largest volcano in Europe — Elbrus can wake up again. The last time he poured lava into the I-II century AD, but the climbers and now meet at the top of its jets of hot gas — fumaroles. By analogy with the volcanoes of Kamchatka, which can settle on one and a half to two thousand years, and then "as zhahnut", scientists are worried that Elbrus is inspect your last dream. According to geophysicists, at a depth of 1-3 km beneath the volcano is "live" magmatic center, filled with melt. The magma heats the rocks, so mineral water getting hotter as you get closer to Elbrus. For geologists are signs of recent activity of the volcano, so they offer a comprehensive set of him watching.

Even a small eruption of Mount Elbrus would be disastrous for the people living at the foot of it as the top and slopes of the mountains are covered with six cubic kilometers of ice. When the glacier melted, then floods and lahars (mud flows hot) desolate area in a matter of minutes. This happened in 1985 in Colombia during the eruption of the volcano Ruiz, when the city of Armero with a population of 23 thousand people was cemented with mud boiling for 40 minutes. According to the Kamchatka volcanologists and lahars moving at a speed of 40-50 km / h, the height of its waves inside the valley is 20 m

Ash (particles of volcanic glass) — is also a very dangerous weapon volcano. With a large increase can be seen that each particle sharp jagged edges. Sprinkle ashes on his head this, it will not wash off, he firmly adheres to the soft surfaces of him dying vegetation and animals. In 1991, the Chilean volcano ash fell asleep Hudson valley where large herds peacefully grazing livestock. Inhaling polluted air, and after eating grass with broken glass, killing 100 thousand.

The last hundred years, the Caucasus, as well as the neighboring mountainous area rocked by a strong earthquake. This area is one of the collision of two continental blocks and still is compressed at a rate of 12 mm per year. Simply put, the mountain continues to grow, so it is possible that at some point Elbrus again wake up. Resumption of tectonic activity in the Caucasus coincided with the recent increase in the level of the Caspian Sea, changed the economic infrastructure of coastal areas to the extent that we can talk about the environmental disaster — the sinking of communications, oil wells, buildings, salinity and flooding of vast lands. However, the relationship between these two phenomena is still a hypothesis.
