On August 13, 2021, there was an eruption of Fukutoku-Oka-no-Ba submarine volcano, located between Iwo Jima and Minami Iwo Jima in the southernmost part of the Ogasawara Islands, approximately 1,300 km from Tokyo. The volcanic plume reached a height of 16 km and ejected a large amount of pumice, which floated over the Pacific Ocean.Some of the floating pumice drifted to the Ryukyu Islands, reaching the main island of Okinawa and Amami-Oshima in early October 2021. As of June 2022, floating pumice was still affecting marine traffic, fishing, and tourism in the area. This article presents satellite images of the eruption and the drifting floating pumice stone.
