Rabaul, the former provincial capital, has quite a remarkable location. The town is inside the flooded caldera of a giant volcano and several sub-vents are still quite active today! The fumes of the volcano Tavurvur can be seen continually and the town suffered greatly during the last major eruption of 1994 when some 80% of the houses collapsed due to the ash raining down onto their roofs. Rabaul has a Volcano Observatory sitting atop the town’s center, monitoring the 14 active and 23 dormant volcanoes in Papua New Guinea. A small museum opposite the bunker used by Yamamoto during World War II shows exhibits relating to Rabaul’s local, German, Australian and Japanese past from the 19th century to Papua New Guinea’s independence in the 1970s.
