A stratovolcanic island in the Sunda Strait between the Indonesian islands of Sumatra and Java. Prior to its massive 1883 eruption, there were three separate volcanic peaks: Perboewatan (completely destroyed by the eruption), Rakata (extant), and Danan (almost completely destroyed). The 1883 eruption of Krakatoa killed more than 35,000 people and is believed to have produced the loudest sound ever. Krakatoa is one of the largest volcanoes in the Pacific Ring of Fire. The continued activity of Krakatoa formed a new island, Anak Krakatau (or 'Child of Krakatoa') in 1927.
