Fukutoku-Oka-no-Ba volcano (Volcano Islands, Japan) - Smithsonian / USGS Weekly Volcanic Activity Report for 29 June-5 July 2005 (New Activity / Unrest)
On the evening of 2 July, members of the Japan Coast Guard observed a steam plume rising ~1 km above the sea near the island of Minami-Iwo-jima. On 3 July, JMA confirmed that a small-scale eruption had occurred at the submarine volcano Fukutoku-Okanoba, prompting the Japan Coast Guard to issue a warning against sailing in the area. Observers saw rock and mud rising to the sea's surface near the volcano and a ~1-square-km area of water that had turned orange-brown.
