"Lolobau volcano sits astride the western rim of a 6-km-wide caldera, which formed about 12,000 years ago. The 8 x 13 km, oval-shaped Lolobau 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 that is breached to the NE. Flank cones are found along the coast of the largely submerged volcano. Several vents within the caldera along an E-W-trending line on the eastern flank of Mount Lolobau have been active during historical time. The latest eruptions took place during the early-20th century."  -Smithsonian Volcano Archive
