Mokuyo volcano is an active seamount belonging to the 7 Shichiyo Seamounts, named for the 7 days of the week. Mokuyo ("Thursday") contains a basaltic-andesite submarine caldera that rises 1780 m from the sea floor to within 920 m of the sea surface. The summit caldera is 3 x 2.3 km wide and about 450 m deep. It contains a 180-m-high lava dome in its center. Major hydrothermal activity was observed in July 1990, and the volcano was reclassified as active by the Japan Meteorological Agency.
