What is Krakatoa?

Krakatoa is a volcanic complex in the Sunda Strait between the Indonesian islands of Java and Sumatra. It is best known for its catastrophic eruption in 1883, which destroyed much of the original island of Krakatoa and generated deadly tsunamis that killed over 36,000 people. The active volcanic island Anak Krakatau (“Child of Krakatoa”) later emerged within the resulting caldera.
