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 serious threat to aviation.
“The height of the most powerful of the ash emissions registered on Tuesday reached 7.8 kilometers,” – said the source.
According to him, Shiveluch assigned an “orange” code, indicating the high risk to aviation. Particles of volcanic ash in contact with the mechanisms of planes and helicopters can cause them to malfunction.
In the vicinity of 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.
