SOFAR signals resembling those produced at known submarine eruptions were recorded in January 1972 at a location in the central Bismarck Sea (Johnson et al, 1981). The source of the signals was at the junction of two segments of the northern margin of the South Bismarck plate. The more easterly of these segments is a transform fault, whereas the more westerly is an area of oblique active seafloor spreading. The signals were detected at a seismic station on nearby Manus Island, as well as at hydrophone stations on Wake and Midway Islands in the central Pacific.

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.
