BackgroundA previously unknown submarine volcano was discovered in 1992 at the southern end of the South Kermadec Ridge. Rumble V volcano, the southernmost of a group of seamounts on the southern Kermadec Ridge, known as the Rumbles, rises more than 2000 m to nearly 400 m below the sea surface and shows a pristine morphology. Andesitic and basaltic-andesite rocks have been dredged from Rumble V, which lies 17 km ESE of Rumble IV. A large plume of gas bubbles was acoustically detected rising from the summit of Rumble V in 1992, and subsequent expeditions detected evidence of vigorous hydrothermal activity.
