The violent and continuous explosions on Krakatoa as the Batavia Queen steams from Krakatoa to Palembang and then to the vicinity of Anjer late in the movie appear to depict the final, cataclysmic eruption of the volcano on 26-27 August 1883. The huge tsunami that engulfs Anjer and its lighthouse in the film's climactic sequence is consistent with the wave that struck the west coast of Java on the morning of 27 August 1883, rising to a height of 40 meters (135 feet) at Merak and destroying both Anjer - where it was 10 meters (33 feet) tall - and the Fourth Point Lighthouse.
