Increased activity of Shiveluch volcano, whose height is about 3.3 thousand meters above sea level, was launched in May 2009. Its dome is a normal eruption fissure cut through a depth of about 30 meters.
"Video surveillance of the volcano are difficult because of the weather, but the seismic station within 36 minutes of recorded surface seismic event, which was accompanied by powerful ash-gas explosions and gathering glowing avalanche" — a spokesman said.
He added that in satellite images can also be seen dense ash plume, stretching 80 kilometers in the north-west, and the ash cloud 70 kilometers to the north-east.
According to experts, for the settlements of the Kamchatka region, the closest of which — the settlement Keys, 40 kilometers from Shiveluch Volcano is currently no danger. However, there is a possibility ash falls: Volcanic Ash — particles of magmatic material with a diameter of up to two millimeters — can cause poisoning in humans and animals due to the complex chemical composition. Aerosol and ash plume can be hazardous to aviation.
Apart from Shiveluch, the risk to aviation are currently two volcanoes of Kamchatka — Karymsky and Kizimen. Over their craters periodically raise a column of ash, seismic record increased activity in the bowels of giants. All three volcanoes assigned an "orange" code, which informs about the need to comply with security measures.
