The "child" of the legendary Indonesian volcano Krakatau erupted on Thursday, spewing a plume of ash high into the sky as molten lava streamed down from its summit.
Anak Krakatau - a small volcanic island that emerged from the ocean a half century after Krakatau's deadly 1883 eruption - has rumbled back to life in recent weeks, spitting flaming rocks and ash from its crater.
No one lives on Krakatau, which forms a small island in the Sunda Strait between Java and Sumatra, but the peak is a popular tourist spot.
Indonesia's geological agency has not raised the alert level for the mountain. However, there is a 1km no-go zone around its summit.
