MOSCOW, July 3 (UPI) -- Two of the active volcanoes on Russia's Kamchatka Peninsula have been sending plumes of ash as much as 5 miles into the air, scientists said Saturday.
No warnings had yet been issued about air traffic in the area, RIA Novosti reported. Volcanic ash can damage aircraft engines, and an eruption in Iceland earlier this year caused chaos for air traffic in Europe and on trans-Atlantic routes.
