Dramatic footage of eruption of Indonesia's Anak Krakatau volcano

A volcano erupted in Indonesia early Sunday, prompting the cancellation of all flights at Jakarta's Soekarno-Hatta International Airport and disrupting other domestic airports as ash drifted across western parts of the country. The volcanic island of Anak Krakatau, located in Indonesia's Sunda Strait between the main Java and Sumatra islands, had showed signs of activity since Friday before erupting for 30 seconds at 3:53 a.m. Sunday and for 16 seconds about three hours later, Indonesia's Geological Agency said. Closed-circuit camera footage showed lava flares from the volcano.
