Mokuyo Seamount is one of the Shichiyo Seamounts, named for the 7 days of the week. Mokuyo ("Thursday") is 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 and 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.

The Global Volcanism Program is not aware of any Holocene eruptions from Mokuyo Seamount. If this volcano has had large eruptions (VEI >= 4) prior to 10,000 years ago, information might be found on the Mokuyo Seamount page in the LaMEVE (Large Magnitude Explosive Volcanic Eruptions) database, a part of the Volcano Global Risk Identification and Analysis Project (VOGRIPA).

The Global Volcanism Program has no synonyms or subfeatures listed for Mokuyo Seamount.

The Global Volcanism Program has no photographs available for Mokuyo Seamount.

The following references have all been used during the compilation of data for this volcano, it is not a comprehensive bibliography. Discussion of another volcano or eruption (sometimes far from the one that is the subject of the manuscript) may produce a citation that is not at all apparent from the title.
