Krakatoa

Krakatoa (/ˌkrɑːkəˈtə, ˌkræk-/), also transcribed Krakatau (/-ˈt/), is a caldera in the Sunda Strait between the islands of Java and Sumatra in the Indonesian province of Lampung. The caldera is part of a volcanic island group (Krakatoa archipelago) comprising four islands. Two, Lang and Verlaten, are remnants of a previous volcanic edifice destroyed in eruptions long before the infamous 1883 eruption; another, Rakata, is the remnant of a much larger island destroyed in the 1883 eruption.

In 1927, a fourth island, Anak Krakatoa, or "Child of Krakatoa", emerged from the caldera formed in 1883. There has been new eruptive activity since the late 20th century, with a large collapse causing a deadly tsunami in December 2018.
