Eurasia's highest volcano on the Kamchatka Peninsula in Russia's Far East has shown again signs of intensified activity throwing clouds of smoke and ash into the air to a height of 2.5 kilometers.
The Klyuchevskoy, which lies 220 miles north of Petropavlovsk-Kamchatsky, is one of the largest active volcanoes in the world and reaches an altitude of 15,584 feet. It erupts about every 2-3 years.
Local seismologists said on Monday there was no immediate threat to the residents or tourists in the area, but issued an ash emission warning for air traffic in the vicinity of the volcano.
The Klyuchevskoy started a new active cycle with an eruption in August 2009.
There are more than 150 volcanoes on Kamchatka, 29 of them active.
Another volcano in the area, the Bezymyanny, erupted on May 31, sending clouds of ash to the height of 10 kilometers for about 20 minutes.
Experts say that ash from volcanic eruptions pose a threat to aircraft engine turbines and could also cause problems as it settles on aircraft wings.
The eruption on the Eyjafjallajokull Glacier in Iceland, which began April 14, paralyzed air traffic throughout central and northern Europe, leaving thousands of travelers stranded and forcing more than 20 European countries to close their airspace.
