Fukutoku-Oka-no-ba is a submarine volcano located 5 km NE of Minami-Iwojima island (right). Water discoloration is frequently observed near the volcano and several ephemeral islands formed in the 20th century. The first of these created Shin-Iwojima in 1904, and the island seen in this 21 January 1986 photo; wave erosion removed the island by 8 March.
