Rakata ( ), also called 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 (volcano) and Perboewatan) and the only one not totally destroyed in the 1883 eruption. 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." Etymology 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)." Physical features 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. The 1883 eruption Rakata seems to have played a comparatively minor role in the 1883 eruption of Krakatoa. Some reports seem to indicate it started erupting ("venting") in late July, compared to Perboewatan starting in May and Danan in June. (Furneaux mentions an unsourced report that the Peak had collapsed sometime in July.) All eruptive centres of Krakatau have a common source, meaning that they are different vents of a single volcano. The map made by Capt. Ferzaneer from his visit on 11 August shows no eruptive "foci" from Rakata or its slopes (although there are several from the southern part of Danan), but he was not able to investigate the southern or
