An undersea eruption occurred at Fukutoku-Okanoba volcano in the volcano islands, SE of Japan. A column of steam rose 1000 m above the volcano. Observations from a helicopter flyover showed rock and mud rising to the surface. A one-kilometer area of water has turned brown-orange. Eruptions of Fukutoku-Okanoba volcano have previously formed a temporary island, but it is unknown if an island will form this time.
