New eruption with strongly discolored water during August 2022-January 2023

Kaitoku Seamount is a three-peaked submarine volcano located about 1 km S of Tokyo, Japan. The base of the seamount has a diameter of 40 km and a height of 2.5 km above the ocean floor. The two peaks in the south are called Tokai Tokuba and Nishi Tokuba (figure 2). The most recent previous confirmed eruption was in 1984, when discolored water, gas-and-steam plumes, and floating pumice was reported (SEAN 09:10). Water discoloration was observed in December 1984 and June 1986, and the Japan Coast Guard (JCG) described activity in July 2001 which mainly consisted of bubbles. This report covers a new eruption that was characterized by strongly discolored water during August 2022 through January 2023 based on information from the Japan Meteorological Agency (JMA), Japan Coast Guard (JCG), and satellite data.

The JCG received a report on 19 August that discolored water was observed near the volcano on 18 and 19 August. This was also visible in a Sentinel-2 satellite image (figure 3). According to aerial observations by the JCG on 23 and 28 August, both discolored water and floating material were observed. The discolored water was yellow-white, approximately 100 m in diameter, and located near the Tokai Tokuba peak. On 28 August multiple zones of white discolored water were observed directly above the volcano and floating material covered an area approximately 200-m-wide and 6-km-long to the SE (figure 4).

Courtesy of JMA (monthly report of activity at Kaitoku Seamount, August 2022).

Discolored water observations continued during September and October, which was interpreted as ongoing volcanic activity. Sentinel-2 satellite images showed small blue-white discolored plumes on 3, 8, 23, and 28 September that drifted SE, S, SW, and N from a single point. On 16 September an aerial observation conducted by JCG showed blue-white discolored water approximately 20 m wide and 30 m long (figure 5). Strong yellow-blue discolored water was visible on 28 September that mainly occurred around a single point, but a faint plume extended to the N. Though weather clouds sometimes prevented clear views of the vent area, discolored water plumes appeared more frequently in October. On 12 October there was a zone of dense yellow-white discolored water approximately 200 m in diameter; no floating material was observed (figure 6). Sentinel-2 satellite images captured discolored plumes on 3, 8, 13, 18, and 23 October, that mainly encompassed a single area. Part of the plumes extended SW, NW, E, and NE (figure 7).

During November 2022 through January 2023 occasional strongly discolored plumes persisted. Sentinel-2 satellite images captured green-yellow discolored plumes on 22 and 27 November that drifted several kilometers SW and SE (figure 8). An aerial observation conducted by JCG on 25 November showed a yellow-white circular shape of discolored water approximately 300 m in diameter (figure 9). Additionally, blue-white discolored water was observed extending 1 km SW from the volcano and was about 10 km in length. Strong green-yellow discolored plumes were visible in Sentinel-2 satellite images on 17 and 27 December that drifted SE and S as far as 10 km from the vent area (figure 10). Frequent strongly discolored plumes were captured in satellite imagery on 1, 6, 11, 16, and 26 January 2023 that drifted in different directions for several kilometers. On 1 and 16 January white bubbles were also visible around the vent area (figure 11).

After JMA first reported new activity around the Kaitoku Seamount in August, discolored water continued to be periodically visible in Sentinel satellite images through 27 December. Though weather clouds sometimes prevented views of the vent area, and on occasion no activity was visible in clear images, plumes of discolored water drifting away from the vent area appeared to become more frequent in October. Images from 18 October, and 22 and 27 November possibly captured material at the surface or an eruption plume rising above the water. The Japan Coast Guard posted pictures of disturbed water around the vent in November. Recent Sentinel images on 17 and 27 December captured plumes of discolored water drifting as far as 10 km from the vent area.

Large area of discolored water; small plumes

On 7 March at 1230, the crew of a Japan Maritime Self-Defense Force (JMSDF) transport plane flying about 130 km N of Iwo-Jima observed a fan-shaped zone of discolored sea water that extended about [28] km WSW from a submarine vent. The maximum width of the discolored zone was about 9 km. A helicopter flew over the area shortly thereafter and its crew estimated that the extent of the reddish-brown water was roughly as large as Iwo Jima Island (about 5 x 8 km).

The next morning, JMSA personnel observed continuous submarine eruptive activity. Gray or yellowish brown water was ejected every 10 minutes and waves spread outward from the vents. The sea colors included gray, white, yellowish brown, and reddish brown. JMSA observers saw neither plumes nor floating ejecta, although small white plumes and rocks or reefs were seen during a flight by the JMSDF at about noon the same day. On 12 March, personnel aboard a JMSDF patrol plane again saw floating material, and a plume about 100 m above sea level. Only discoloration was found during a JMSA flight 13 March. As of the 13th, no new island had been observed at the eruption site.

The activity was located near the site of an eruption reported in 1543 at 26.00°N, 140.77°E.

Acoustic waves recorded in French Polynesia

RSP stations on Rangiroa, Tubuai, and Rikitéa recorded acoustic waves (T-phase) from a strong submarine volcanic eruption in the vicinity of the Izu Islands. Between 25 March and 30 April, more than 500 signals were received, 300 between 2 and 9 April. Most of the events were impulsive and of short duration, indicating explosive volcanic activity at a shallow depth. Some of the events were emergent and of longer duration indicating quiet emission of lava. J.M. Talandier noted that these events appear to be correlated with the submarine activity reported in 9:2.

Discolored water; floating lapilli; formal name

JMSA observations beginning 7 March indicated that eruptive activity was at its highest level in mid to late March, when floating ejecta and vapor plumes were nearly always seen. Beginning in April, activity subsided gradually. The area of discolored water decreased from 13 x 30 km in early March to 300 m in diameter in early May (table 1).

On either side of the submarine vent are two shallow areas, at 26.13°N, 141.10°E, and 26.05°N, 140.93°E (figure 1). JMSA has formally named the feature Kaitoku Kaizan (Kaitoku Seamount).

Discolored water after 3 months of quiet

JMSA reconnaissance revealed few signs of activity since the March eruption. Pumice was observed only around the eruption site; none washed up on shore.

Activity gradually declined. To the crew that overflew the area at noon on 9 April, the water discoloration was barely distinguishable, and no ejecta or plume was seen (table 1). JMSA and JMSDF saw no discolored water or other activity on 10 and 31 July, 1 August, and 6 and 26 September. However, the crew of the MV Emblem reported a 3.5-5-km area of upwelling and water discoloration on 15 October.

New eruption with strongly discolored water during August 2022-January 2023

Kaitoku Seamount is a three-peaked submarine volcano located about 1 km S of Tokyo, Japan. The base of the seamount has a diameter of 40 km and a height of 2.5 km above the ocean floor.
