Located on the coast of a natural harbor on the eastern coast of New Britain, an island in the Southwest Pacific, Rabaul was a German colony in the 1900s that was captured by the Australians in World War I. Two nearby volcanoes, Vulcan and Tavurvur, erupted violently in 1937, destroying most of the city. After World War II started, it was captured by the Japanese in January 1942, after which it was transformed into a major stronghold with approximately 97,000 troops that would easily fend off Allied attacks until October and November 1943. While the Allies continued to advance towards Japan, they cut off Japanese supply routes to Rabaul and continued to bomb the city and surrounding area. It was officially surrendered at the end of the war. After the war was over, the city became a trading hub until Tavurvur erupted in 1994, once again destroying a large part of the city. Developments closest to the volcano were never rebuilt.
