Background:

Water discoloration, sulfur odor, possible boiling water, and possible minor floating pumice were observed 60 km NW of the tip of Oahu on May 22, 1956. The depth at this location is about 3000 m. Macdonald (1959) suggested that a submarine eruption may have occurred, but noted that evidence is less certain than that for the 1955 report of a submarine eruption near Necker Island.
