Krakatoa

Krakatoa, also transcribed Krakatau, 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 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.
