The northernmost active volcano of Kamchatka — Shiveluch — throws ash column to a height of 9 km, told RIA Novosti the Institute of Volcanology and Seismology.
Increased activity of Shiveluch volcano, whose height is about 3.3 thousand meters above sea level, was launched in May 2009. In the dome of the volcano is a normal eruption formed cleft depth of about 30 meters. For settlements eruption no danger, but plumes threaten aircraft.
"Experts Klyuchevskoy vulkanostantsii 40 kilometers from the giant saw the last day of two strong emission from the crater of Shiveluch. Ash columns reached a height of 8 and 9 kilometers," — said the source.
According to him, in the area of seismic Shiveluch recorded dozens of seismic events, the length of some of them up to 20 minutes. To the south-east from the volcano stretched 58-kilometer ash plume, and at a distance of 186 kilometers drifting particles rich magmatic material cloud.
In the nearby villages to the volcano ash falls are likely.
Volcanic ash — magmatic material particles 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.
