Russia's Kamchatka volcano sends ash 9Km into sky

An active volcano on Russia's Kamchatka Peninsula is currently spewing plumes of ash at a height of up to 9 kilometers about (5.6 miles), Russian scientists reported on Tuesday. Scientists have registered two strong eruptions in the last 24 hours, according to Russian (RIA Novosti) News Agency. The 3,283-meter about (10,771-foot) Shiveluch volcano increased activity in May 2009 and periodically spews ash from three to eight kilometers. Clouds of volcanic ash could pose threat to air traffic because the tiny particles can cause problems with aircraft engine turbines. There are more than 150 volcanoes on Kamchatka, and 29 of them are active.
