The northernmost active volcano of Kamchatka — Shiveluch — throws ash column to a height of 6 km, told RIA Novosti the Kamchatka branch of the Geophysical Service RAS.
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.
"Emissions of ash to a height of 6 km and a cable, which runs to the east, was observed on the last day of Klyuchevskaya vulkanostantsii specialists, located in the village of Keys 40 kilometers from the giant" — the source said.
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, seismograph recorded increased activity in the bowels of giants.
