Introduction
The submarine voldano is basaltic-to-andesitic in composition and lies at the NW end of a chain of submarine volcanoes that includes Eifuku and Daikoko at the SE end. The "white smokers" of NW Eifuku emit hydrothermal fluids including liquid carbon dioxide bubbles. It is one of only 2 places where this has been observed. The hydrothermal field was discovered during a 2003 NOAA expedition and named "Champagne". It is located in the steep headwall of a slope-failure scarp that cuts the summit and SW side of the volcano.(Smithsonian / GVP volcano information)
