Rumble II West Seamount

Rumble II West

成層火山 · New Zealand · 1200m (海底)

A bathymetric map was made during a 2009 voyage on the research vessel R/V Thompson of Rumble II West submarine volcano. Located NW of Rumble II East, Rumble II West, with a summit depth of 1,200 m, is the deepest of the Rumble group of seamounts, but displays evidence of hydrothermal activity. It contains a 2.5-3 km wide summit caldera about 200 m deep with a central cone. Recent lava flows originating from near the caldera rim with little or no sediment cover are on the S flanks.

地質学的概要

Rumble II West, about 12 km NW of Rumble II East, rises 1,800 m from the ocean floor to within 1,200 m of the surface. Bathymetry shows a 2.5-3 km summit caldera about 200 m deep with a central cone. There is evidence of hydrothermal activity, and cones are present on the flanks. Some lava flows on the western flanks originating from near the caldera rim have little or no sediment cover.
