Suiyo Seamount, one of the Shichiyo Seamounts, named for the 7 days of the week, lies south of Sofugan volcano. Suiyo ("Wednesday") is an basaltic-to-dacitic submarine caldera and lava dome that rises abaout 1400 m from the sea floor to within 1418 m of the sea surface. The summit caldera is 1.5 km wide and about 500 m deep. Major hydrothermal activity was observed in July 1991, with temperatures reaching more the 290 degrees Centigrade, and the volcano was reclassified as active by the Japan Meteorological Agency.
The Global Volcanism Program is not aware of any Holocene eruptions from Suiyo Seamount. If this volcano has had large eruptions (VEI >= 4) prior to 10,000 years ago, information might be found on the Suiyo 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 Suiyo Seamount.
The Global Volcanism Program has no photographs available for Suiyo 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.
