Fukutoku-Okanoba on 3 July 2005 from the NE shows a plume of debris and discoloration extending from the arrow. On the previous day a white plume was observed at Fukutoku-Okanoba, which later was observed to have reached ~1 km above the sea surface. Numerous large and steaming blocks were seen floating on the ocean surface at mid-day on 3 July. The island in the background is Shin-Iwojima.
