Macdonald Seamount rises to within 27 m of sealevel (Rubin and Macdougall, 1989) and has had several eruptions since it was first observed in 1969 (see Johnson, 1970; Johnson and Malahof, 1971). Our choice of its track starts at Macdonald, The evolution of volcano-seismie activity, as evidenced by the various surveys made at seven-year intervals, suggests that the searnount's emergence could occur relatively rapidly.
