Twin submarine volcanoes, known informally as Volcano W, were discovered during a New Zealand-American submarine vent mapping expedition to the Kermadec arc in 2004. The two deep-water basaltic volcanoes lie SW of Curtis Island. The summits of both volcanoes are cut by small calderas, and evidence of diffuse hydrothermal venting was observed on the SE volcano in 2005. The SE volcano rises to within about 900 m of the sea surface and contains a cone in its summit caldera. The caldera walls expose pillow lavas, pillow tubes, localized sheet flows, and pillow breccias, with higher proportions of volcaniclastic breccias in the upper portion.

The Global Volcanism Program is not aware of any Holocene eruptions from Volcano W. If this volcano has had large eruptions (VEI >= 4) prior to 10,000 years ago, information might be found on the Volcano W page in the LaMEVE (Large Magnitude Explosive Volcanic Eruptions) database, a part of the Volcano Global Risk Identification and Analysis Project (VOGRIPA).

The Global Volcanism Program has no synonyms or subfeatures listed for Volcano W.

This map view shows the twin submarine volcanoes known informally as Volcano W. The Pisces V dive area during a 2005 New Zealand-American expedition is indicated on the SE caldera. The contour interval is 100 meters. The resolution of the bathymetry data is 25 meters.

Twin submarine volcanoes, known informally as Volcano W, were discovered during a New Zealand-American mapping expedition in 2004. This view taken at the SE volcano from a submersible vehicle during a 2005 expedition shows toothpaste-like lava at Volcano W that oozed from this tube before it solidified in place. The SE volcano rises to within about 900 m of the sea surface and contains a cone in its summit caldera.

An anemone clings to relatively young lava flows at Volcano W. This view was taken on the SE volcano of the twin submarine volcanoes known as Volcano W on a 2005 New Zealand-American expedition to study submarine vents in the Kermadec arc.

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.
