Rakata or Greater Krakatau ( ) is a partially collapsed stratovolcano on the Indonesian island of Krakatoa ( ) in the Sunda Strait between the islands of Sumatra and Java . Standing tall , it was the largest and southernmost of three volcanoes that formed the island Krakatoa ( the others being Danan and Perboewatan ) and the only one not totally destroyed in the eruption of 1883 . Rakata is the last remnant of the original island prior to its destruction . However , Rakata did lose its northern half in that eruption , leaving just its southern half . The exposed cliff is quite striking visually , partially of a large exposed dike terminating in a large lenticular extrusion at the middle of the almost vertical cliff . The feature has been called " the Eye of Krakatoa . " 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 ) . " Rakata is a volcanic cone with its northern face being a vertical cliff , exposing much of its eruptive history . More than 25 extrusion dikes have been counted ; the largest at the center runs from sea level to 320 meters above and terminates in a large ( about 6 meters in diameter ) , convex form . It is not known if the two are actually related in origin or just coincidental
