All times are local (unless otherwise noted)

Discolored water around the Kaitoku Seamount was visible in 1 and 6 January Sentinel satellite images. Concentric circles of discolored water radiated out from the vent area and a plume drifted W. The plume of discolored water extended S in the 6 January image.

Geological Summary. Submarine eruption have been observed during March 1984 and August 2022-January 2023 from Kaitoku Seamount (Kaitoku Kaizan), a three-peaked submarine volcano 80 km NNW of Kita-Ioto. The type of activity related to other observations of discolored water or bubbling, including an observation from 1543 CE, is uncertain.
