MOSCOW, Russia: The Kamchatka Volcanic Eruption Response Team has reported that the Shiveluch volcano on the Kamchatka Peninsula in Russia's Far East has become extremely active and could erupt.
"A growth of the lava dome continues, a strong fumaroles activity, an incandescence of the lava dome, explosions, and hot avalanches accompanies this process," the observatory said on its website.
"Ash explosions up to 10 to 15 kilometres could occur at any time. Ongoing activity could affect international and low-flying aircraft," it added.
Russia's state RIA news agency reported that Alexei Ozerov, director of the Institute of Volcanology and Seismology of the Far East Branch of the Russian Academy of Sciences, stated that the dome of the volcano has become very hot.
"At night, the dome glows almost over its entire surface. Hot avalanches with a temperature of 1000 degrees Celsius roll down the slopes, pyroclastic flows descend. This state of the dome is observed, as a rule, before a powerful eruption," he said.
One of Kamchatka's largest volcanoes, Shiveluch, which has a summit reaching 3,283 meters, has had an estimated 60 substantial eruptions in the past 10,000 years.
According to NASA, the volcano's last most powerful eruption took place in 2007.
