Indonesia's Krakatau roars, dazzles with fireworks

Indonesia's Anak Krakatau volcano lets out a massive roar as it blasts a gigantic cloud of smoke and flaming red rocks hundreds of metres into the night sky.

A few hours later, a river of lava and stones glowing like embers glide down the slopes of Mount Anak Krakatau as the muted light of the rising sun tries to break through thick clouds settled above the mountain.

The volcano, whose name means "Child of Krakatau", formed in the Sunda Strait close to Java island after Mount Krakatau's legendary eruption in 1883. It rumbled to life about two weeks ago and since then has been dazzling scientists and visitors with its amazing pyrotechnics.
