Satellite images from Himawari confirmed a steam and gas plume that extended to the west of the volcano. The height of the plume is unknown and was not reported yet, but from available imagery seems to be of tens-to-hundreds meters above sea level.
Fukutoku-Okanoba is a submarine volcano 5 km NE of the small pyramidal island Minami-iwo-jima in the Japanese Volcano Island chain. Eruptions and submarine hydrothermal activity often cause water discoloration in the area, and during eruptions, the volcano has built several temporary new islands. The first observation of a new island was in 1904-05 when it formed Shin-Iwo-jima ("New Sulfur Island"). Small new islands were also formed during the eruptions in 1914 and 1986.
