P3017747 Rabaul volcano chart

Rabaul has volcanoes on its volcanoes with three main groups which vary in age over thousands of years. Even the volcanoes located in close proximity around the old town, earlier seen as part of the harbor caldera wall, are separate from the active Tavurvur and Vulcan which are part of the harbor complex. A massive underwater caldera off Tavui north of Rabaul town was identified only as recently as the 1980s. Its precipitous descent into the depths provided the Japanese navy with a deep water port submarines used to bring supplies to the beleaguered Rabaul garrison during World War II. P3017747
