Lolobau volcano has grown over the W rim of a 6-km-wide caldera which formed about 12,000 years ago. The 8 x 13 km island is located just off the coast of eastern New Britain. A small lake occupies the SW part of the caldera. A small lava dome (Hulu) caps Mount Lolobau, which has a 0.8 x 1.1 km summit crater breached to the NE. Flank cones are found along the coast of the largely submerged volcano. Several vents within the caldera, on the E flank of the main edifice, have been active during historical time. The latest eruptions took place during the early 20th century.
