The Dakataua Caldera is located at the northern tip of the Willaumez Peninsula, New Britain, Papua New Guinea. The peninsula includes the 350 m high andesitic Mount Makalia stratovolcano.{{cite gvp|name=Dakataua|vn=252040|access-date=2021-06-25}} The last major collapse of Dakataua was during the Holocene around 800 CE.{{cite web|url=https://www.sciencedirect.com/science/article/abs/pii/1040618295000704|title=Holocene explosive eruptions of Witori and Dakataua caldera volcanoes in West New Britain, Papua New Guinea|access-date=August 19, 2020}} The most recent eruption on the caldera's rim was Mount Makalia in 1890, producing lava flows and cinder cones.{{cite web|url=http://volcano.oregonstate.edu/dakataua|title=Dakataua Volcano World|access-date=August 19, 2020}}
Caldera lake
Dakataua's caldera lake is about 76 m above sea level; it has a total surface area of {{convert|48|km2|abbr=on}} and a maximum depth of approximately 120 m.E. BALL, J. GLUCKSMAN A limnological survey of Lake Dakataua, a large calderalake on West New Britain, Papua New Guinea, with comparisons to Lake Wisdom, a younger nearby caldera lake. Freshwater Biology (10)73, 1980 It is horseshoe shaped, roughly bisected by a peninsula. It is a freshwater lake that is alkaline with a pH of up to 8.2. It is presumed to be formed by rainwater gradually filling in the caldera.{{cite web|url=http://www.jimmyod.com/lake-dakataua/|title=Lake Dakataua|access-date=August 19, 2020}} While the lake supports various kinds of life, it does not support any species of fish.{{cite journal|url=https://onlinelibrary.wiley.com/doi/abs/10.1111/j.1365-2427.1980.tb01182.x|title=A liminological survey of Lake Dakataua|doi=10.1111/j.1365-2427.1980.tb01182.x |access-date=August 19, 2020|url-access=subscription}}
Migo the Lake Monster
There is a folk legend that a monster called the migo (or masali) inhabits the lake. In 1993 a Japanese film crew led by Tetsuo Nagata captured what they claimed to be the migo on film. It is presumed that the creature in the video is actually a saltwater crocodile from the ocean surrounding the lake.{{cite web|url=https://scienceblogs.com/tetrapodzoology/2008/10/27/filming-migo-the-monster|title=Filming Migo the Monster|access-date=August 19, 2020}}
