The active Kizimen Volcano on Russia's Kamchatka Peninsula continues spewing plumes of ash at a height of up to six kilometers (3.72 miles), a representative for the Russian Academy of Sciences' Institute of Volcanology and Seismology said on Thursday.
"Seismologists registered about 200 local tremors in the vicinity of the volcano over the past 24 hours," the spokesman said.
According to him, bad weather satellites cannot track the direction or the distance of the ash plume which has repeatedly caused falling ash in populated areas on the peninsula, including Petropavlovsk, where 60% of the Kamchatka Peninsula residents live.
However, the ash could affect the operations of aircraft. Particles of ash may get into the mechanisms of airliners and provoke an accident.
There are more than 150 volcanoes on Kamchatka, 29 of them active.
The Kizimen Volcano is located 265 kilometers from Petropavlovsk Kamchatsky. Kizimen's last eruption with lava flows occurred at the end of the 1920s. The volcano again became active last June and a new eruption began in December. Scientists have not ruled out the volcano may produce lava flows in this latest eruption.
