NW Eifuku is a small submarine volcano that pales in size in comparison to its larger neighbors, but displays vigorous thermal activity. The summit of the basaltic-to-andesitic Northwest Eifuku volcano lies 1535 m below the sea surface; the seamount lies at the NW end of a chain of submarine volcanoes that includes Eifuku and Daikoko, at the SE end. Hydrothermal fluid emission at NW Eifuku includes liquid carbon dioxide bubbles venting from "white smokers," one of only two places where natural liquid carbon dioxide emission has been observed. The hydrothermal field, named Champagne, was discovered during a 2003 NOAA expedition and lies in the steep headwall of a slope-failure scarp that cuts the summit and SW side of the volcano.
The Global Volcanism Program is not aware of any Holocene eruptions from NW Eifuku. If this volcano has had large eruptions (VEI >= 4) prior to 10,000 years ago, information might be found on the NW Eifuku page in the LaMEVE (Large Magnitude Explosive Volcanic Eruptions) database, a part of the Volcano Global Risk Identification and Analysis Project (VOGRIPA).
This compilation of synonyms and subsidiary features may not be comprehensive. Features are organized into four major categories: Cones, Craters, Domes, and Thermal Features. Synonyms of features appear indented below the primary name. In some cases additional feature type, elevation, or location details are provided.

|White smokers rise above chimneys at NW Eifuku submarine volcano, as photographed by a NOAA expedition in 2006. The bubbles are liquid carbon dioxide; Northwest Eifuku is one of two places where natural liquid carbon dioxide emission has been observed. NW Eifuku is a small submarine volcano that pales in size in comparison to its larger neighbors, but displays vigorous thermal activity. The summit of the basaltic Northwest Eifuku volcano lies 1551 m below the sea surface.

The following references have all been used during the compilation of data for this volcano, it is not a comprehensive bibliography. Discussion of another volcano or eruption (sometimes far from the one that is the subject of the manuscript) may produce a citation that is not at all apparent from the title.
