Water discoloration, sulfur odor, possible boiling water, and possible minor floating pumice were observed 60 km NW of the tip of Oahu on 22 May 1956. There is a seamount at that location at a depth of about 1200 m at the end of the Kaena Ridge. 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.
