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 centers 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 August 11 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 western parts of the island due to the ash cloud blowing in that direction.
