Photo Gallery

The submarine topography of the 6-7 km wide Myojin Knoll caldera is seen in this Sea-Beam image viewed from the SW. The white line marks the E-W track of the survey vessel. A voluminous blanket of coarse rhyolitic 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. An active hydrothermal vent field lies on the eastern caldera floor and has produced a polymetallic sulfide deposit extraordinarily rich in gold and silver.
