Kamchatkan Shiveluch Volcano spews ash 9 km high
"The volcanic event occurred on Tuesday afternoon. The ash cloud stretched northwest, bypassing populated areas," the report said.
No ashfall has been reported from towns nearby, it added.
Nevertheless, rescuers advised tour operators to avoid paths around the volcano, for which a red alert has been issued.
Shiveluch is the northernmost active volcano of Kamchatka situated 45 kilometers away from the town of Klyuchi in the Ust-Kamchatsky district with a population of approximately 5,000.
It is also one of the largest Kamchatkan volcanoes. Shiveluch became active in May 2009 and got a fissure that is almost 30 meters deep in its dome.
