Rumble V Seamount

Rumble V

Stratovulcano · New Zealand · 400 m (sottomarino)

A bathymetric map view shows Rumble V submarine volcano at the southern end of the South Kermadec volcano group. A large plume of gas bubbles was acoustically detected rising from the summit in 1992. Rumble V, the southernmost of a group of seamounts on the southern Kermadec Ridge known as the Rumbles, rises more than 2,000 m to about 400 m below the sea surface.

Sintesi geologica

Rumble V was discovered in 1992 at the southernmost end of the Rumble seamounts on the southern Kermadec Ridge, 17 km ESE of Rumble IV. Andesitic and basaltic andesite rocks have been dredged from this volcano, which rises more than 2,000 m to nearly 400 m below the ocean surface and shows a pristine morphology. A large plume of gas bubbles was acoustically detected rising from the summit in 1992, and subsequent expeditions detected evidence of vigorous hydrothermal activity.
