Fukutoku-Oka-no-Ba, seen here in 1986, is a submarine volcano located 5 km NE of Minami-Ioto island (right). Water discoloration is frequently observed near the volcano and several ephemeral islands have formed in the 20th century. The first of these formed Shin-Iwojima in 1904, and the most recent island is seen in this 21 January 1986 photo. Wave erosion removed the island by 8 March. The volcano is part of an elongated edifice with two major topographic highs trending NNW-SSE. Photo by G. Iwashita, 1986 (Japan Meteorological Agency).
