The ongoing eruption had started as a submarine eruption almost one year ago, when it built a second island to the SE of the existing one. In early January this year, the growing new island had merged with the old one, and has been growing in size ever since.
Culture Volcan Blog posted the attached Landsat 8 photo from 8 Oct which shows that the old Nishino-Shima island has now disappeared under fresh lava flows.
Since late June-early July, the lava flows had been spreading northwards, covering more and more of the older land.
The surface of Japan's newest land is approximately 6 square km.
