Volcanic Activity at Krakatau
This page contains archived content and is no longer being updated. At the time of publication, it represented the best available science. However, more recent observations and studies may have rendered some content obsolete.
Indonesia’s Anak Krakatau Volcano released a small steam plume on July 7, 2009, as the Advanced Land Imager (ALI) on NASA’s Earth Observing-1 satellite passed overhead. This true-color image shows the volcanic island, largely devoid of vegetation except along the coast, and neighboring green Krakatau Kitjil. A white plume blows away from the summit and toward the southwest. The plume’s light color suggests that it consists primarily of steam.
Anak Krakatau means “Child of Krakatau” and the volcanic island formed in the caldera of Krakatau Island, which erupted spectacularly in 1883, completely destroying nearby Danan and Perbuwatan Volcanoes, spawning tsunamis, and claiming more than 36,000 lives. Anak Krakatau has experienced frequent eruptions since 1927.
Krakatau is sometimes misstated as Krakatoa.
