The submarine topography of the 6-7 km Myojin Knoll caldera is seen in this SeaBeam image viewed from the SW. The white line marks the E-W track of the survey vessel. A voluminous deposit of coarse pumice from the caldera-forming eruption mantles the caldera rim and its outer flanks. A post-caldera lava dome rises 250 m above the caldera floor. · Foto: Image by Fumitoshi Murakami (Geological Survey of Japan, courtesy of Richard Fiske, Smithsonian Institution).
