Tangaroa submarine volcano in the southern Kermadec Arc is elongated in a NW-SE direction with a summit that rises to within 600 m of the sea surface. It lies between the Clark and Rumble V submarine volcanoes near the southern end of the Kermadec arc. It is one of more than a half dozen volcanoes in this part of the arc showing evidence for active hydrothermal vent fields. Smaller cones lie on the SE flank, and a larger edifice is located further SE. Courtesy of Ian Wright (National Institute of Water and Atmospheric Research (NIWA), Wellington, New Zealand).
