Submarine eruption from unknown source detected acoustically

Card 1393 (19 May 1972) Submarine eruption from unknown source detected acoustically

"Seismic-type drum recordings of sound-power level at deep-ocean sound channel (SOFAR) hydrophones at Wake, Midway, and Oahu islands show a signal which I interpret to be from a shallow submarine eruption in the Kuril Islands, probably between Simushir Island and Urup Island. (The acoustic record is similar to that of the . . . Myojinsho eruption of 1970.) It began at 29 April 0830 UT and the major activity was over by 1930 UT although scattered events may have occurred for another day."
