Tavui is a large, mostly submerged caldera offshore from east New Britain, Papua New Guinea. It has impressive 1000 m cliffs at a location called Submarime Base, a popular diving spot in New Britain.
The volcano was last active about 7000 years ago and might still be considered active.

Beschreibung
From Smithsonian / GVP volcano information:The spectacular mostly submarine Tavui caldera lies off the NE tip of the Gazelle Peninsula north of Rabaul caldera. The caldera was first discovered during a bathymetric cruise in 1985. The SW wall of the roughly 10 x 12 km wide Tavui caldera cuts the NE tip of the peninsula and extends from Tavui Point at the northern tip of the peninsula SE to Laweo Point.
The 7100-year-old Raluan Ignimbrite, initially thought to have originated from Rabaul caldera, is now thought to have been produced by an eruption of Tavui caldera. A basaltic scoria layer immediately underlies the rhyolitic ignimbrite, and the introduction of basaltic magma was considered to have triggered the rhyolitic eruption. The lack of a major low-velocity region detectable beneath the caldera during a seismic tomography survey suggests that it is not currently active.
