Details for: Minami-Hiyoshi
Minami-Hiyoshi submarine volcano (center) is seen in this Japan Coast Guard bathymetric image with north to the right. Periodic water discoloration and water-spouting have been reported over this submarine volcano since 1975, when detonations and an explosion were also reported. Minami-Hiyoshi lies near the SE end of a coalescing chain of youthful seamounts and is the only historically active vent. The morphologically youthful seamount Naka-Hiyoshi (upper right) lies to the NW and Ko-Hiyoshi seamount (left) to the SSE.
