Two large cones have been constructed on the NW and NE rims of a roughly 3-km-wide submarine caldera at Nikko. The caldera rim is prominently displayed on the southern side and is largely buried to the north. A smaller cone fomed on the SE caldera floor. Discolored water has frequently been observed above the seamount and hydrothermal venting was documented at the main cone during a NOAA expedition.
