Rumble III Seamount

Rumble III

Estratovolcán · New Zealand · 220 m (submarino)

The Rumble III seamount, the largest of the Rumbles group along the South Kermadec Ridge, rises 2,300 m from the sea floor to within about 200 m of the sea surface. Edifice collapse has left a large horseshoe-shaped scar breached to the W. Fresh-looking andesitic rocks have been dredged from its summit and basaltic lava from its flanks. Rumble III has been the source of several submarine eruptions detected by hydrophone signals.

Resumen geológico

Rumble III seamount, the largest of the Rumbles group of submarine volcanoes along the South Kermadec Ridge, rises 2,300 m from the seafloor to within about 200 m of the surface. Collapse of the edifice produced a scarp open to the west and a large debris-avalanche deposit. Fresh-looking andesitic rocks have been dredged from the summit and basaltic lava from its flanks. It has been the source of several submarine eruptions detected by hydrophone signals.
