Alaskan Volcano May Become Threat to Air Traffic

Feb. 1 (Bloomberg) -- Scientists are watching Alaska’s Mount Cleveland on the Aleutian Islands because it may become a threat to air traffic, said John Power, scientist in charge at the Alaska Volcano Observatory. Mount Cleveland, about 5,600 feet high, has exploded almost every year since 2005 and was particularly active in the last half of 2011, Power said. Its last blast was five weeks ago. Earlier this week, scientists detected a new lava dome forming at the top of the mountain, an indication it may explode again. The Volcano Observatory issued an orange warning, the second highest on its four-step scale for aviation alerts.
