Geological Summary

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 caldera cuts the NE end 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, is now thought to have been produced by an eruption of Tavui. 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.

The mostly submarine Tavui caldera at the NE end of New Britain lies off the tip of the Gazelle Peninsula. The SW wall of the roughly 10 x 12 km wide caldera, its margins crudely shown on this image, cuts the NE tip of the peninsula. Tavui caldera, much less known than its prominent neighbor to the south, Rabaul caldera, was first discovered during a bathymetric cruise in 1985. Light ash-covered areas from the 1994 Rabaul eruption can be seen at the western and NE margins of Rabaul caldera in this 1999 NASA Space Shuttle image.

The following references have all been used during the compilation of data for this volcano, it is not a comprehensive bibliography. Discussion of another volcano or eruption (sometimes far from the one that is the subject of the manuscript) may produce a citation that is not at all apparent from the title.
