A new island at the Fukutoku-Okanoba submarine volcano on 28 January 1986. It was first seen on 20 January, four days after fishing boats first observed an eruption plume rising from the sea. The island reached a maximum size of 400 x 600 m, with a height of 15 m. By 22 January explosive activity had ceased, and the island was completely eroded away by the sea by 8 March. Photo by G.
