Background
The Rumble III seamount, the largest of the Rumbles group of submarine volcanoes along the South Kermadec Ridge, rises 2300 m from the sea floor to within about 200 m of the sea surface. Collapse of the edifice produced a horseshoe-shaped caldera breached to the west and a large debris-avalanche deposit. Fresh-looking andesitic rocks have been dredged from the summit of Rumble III and basaltic lava from its flanks. Rumble III has been the source of several submarine eruptions detected by hydrophone signals. Early surveys placed its depth at 117 m, and later depths of about 200 m, 140 m, and 220 m were determined.---
