Ash clouds from the eruption of Shiveluch volcano on Kamchatka drift at heights of 3 to 8,000 miles, according to RIA Novosti, the representative of 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 pose a threat to aviation.
"The clouds are clearly visible on satellite images, drift at about 30 kilometers from the volcano," — said the source.
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.
