History
The earliest recorded eruption of Fukutoku-Okanoba in 1904 formed an ephemeral island named Shin-Iwo-jima (New Sulfur Island). Other ephemeral islands have also formed, the most recent of which formed in 1986.[1] The most recent eruption of Fukutoku-Okanoba was in 2010, when the Japanese coast guard spotted steam rising one kilometer above the ocean and water discoloration of the surrounding area.[2]
