Hydrophones detected signals in 1972 interpreted to be from a submarine eruption in the Kuriles, probably between Simushir and Urup Island (Smithsonian Institution Center for Short-Lived Phenomena). Three seamounts have been located between Urup and Simushir Islands, east and NE of Chirpoi Island (Tsvetkov 1991, pers. comm.), but the hydrophone signal is not accurately enough located to determine its precise origin. The location given here is arbitrarily that of the seamount most centrally located between Urup and Simushir Islands.
