Because the words Rakata and Krakatau are the same in Indonesian, both names are used interchangeably, leading to confusion in languages which distinguish between the two words. In geological usage, Krakatau is the island and Rakata is the main volcanic cone on that island. But Krakatau is also used for the volcanic edifice as a whole, including all four islands (Krakatau, Anak Krakatau, Verlaten and Lang) of the Krakatoa Archipelago. Before 1883 (and in many of the eruption reports), Rakata was just referred to as the Peak (of Krakatau).
