The Japan Meteorological Agency (JMA) reported that no signs of eruptive activity at the Kaitoku Seamount have been observed since discolored water and floating material were identified in January 2023. At 1100 on 14 February the “eruption warning” status was lowered to “eruption forecast” based on a two-level scale used for underwater volcanoes.
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.
