A hydrophone signal was detected in 1963 from a submarine eruption near the Norfold Island Ridge in the SW Pacific about 450 km SSE of New Caledonia. A ship shortly thereafter observed large amounts of floating pumice from an area consistent with the hydrophone signal source. The Norfolk Island Ridge rises at least 1100 m from a typical basin depth of 3500 m in this area. The location listed here is that of the floating pumice observation. Pumice has been also been observed previously at this location (Kibblewhite, 1966).

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.
