The Dakataua Caldera is located at the northern tip of the Willaumez Peninsula, New Britain, Papua New Guinea.

[2] The most recent eruption on the caldera's rim was Mount Makalia in 1890, producing lava flows and cinder cones.

[3] Dakataua's caldera lake is about 76 m above sea level; it has a total surface area of 48 km2 (19 sq mi) and a maximum depth of approximately 120 m.[4] It is horseshoe shaped, roughly bisected by a peninsula.

[6] There is a folk legend that a monster called the migo (or masali) inhabits the lake.

It is presumed that the creature in the video is actually a saltwater crocodile from the ocean surrounding the lake.
