The 10.5 x 13.5 km Dakataua caldera, anchoring the northern tip of the Willaumez Peninsula, is one of New Britain's most dramatic volcanoes. A major submarine debris-avalanche deposit NE of the volcano may represent edifice collapse prior to caldera formation. The latest episode of caldera formation occurred as recently as about 1150 years ago, and was followed by at least 5 subplinian or vulcanian eruptions. A 12-km-wide, freshwater lake whose surface is only about 50 m above sea level occupies the caldera. Two vertical fault-bounded blocks form topographic highs at the western and eastern sides of the caldera. A N-S-trending line of post-caldera cones, explosion craters, and part of an arcuate inner caldera rim form a large peninsula that nearly bisects the horseshoe-shaped caldera lake. The peninsula includes the 350-m-high andesitic Mount Makalia stratovolcano, the largest of the post-caldera cones, which last erupted during the late-19th century. Thermal areas occur at several locations along the central peninsula.

This compilation of synonyms and subsidiary features may not be comprehensive. Features are organized into four major categories: Cones, Craters, Domes, and Thermal Features. Synonyms of features appear indented below the primary name. In some cases additional feature type, elevation, or location details are provided.

The youngest-known eruption of Dakataua caldera produced these cones on Mount Makalia, probably during the 1890's. The right-hand vent produced a lava flow, still only partly vegetated, that descends the eastern flank of Mount Makalia. The cones are located along a N-S-trending chain of cinder cones and maars that cuts across the 12-km-wide caldera lake.

This sparsely vegetated lava flow appears to be the youngest within Dakataua caldera. It may have been emplaced at the time of the latest known eruption, which took place during the 1890's from Mount Makalia, a post-caldera cone. Mount Makalia is one of several young volcanic features occupying a 7-km-long peninsula that nearly bisects the caldera lake.

The 10.5 x 13.5 km Dakataua caldera anchoring the northern tip of the Willaumez Peninsula is one of New Britain's most dramatic volcanoes. The latest episode of caldera formation occurred as recently as about 1150 years ago. A 12-km-wide, crocodile-infested freshwater lake (foreground), whose surface is only about 50 m above sea level, occupies the caldera. This view from the west shows two maars (right center) and Mount Makalia (upper left), which are located along a N-S-trending peninsula that nearly bisects the caldera lake.
