Surtseyan activity near Nishima-Shima Island where a new island was formed (Japanese Coast Guard via Blog Culture Volcan)A new island was born today in the Pacific Ocean in Japan's Izu (or Volcano) island chain. It is produced by a new submarine eruption which is currently taking place about 500 m southeast of Nishino-Shima island.
The eruption was first spotted by Japanese navy this morning at 10:20 (local time) who documented surtseyan activity at the eruption site (explosive interaction of sea-water and lava, generating violent jets of steam and ash). It appears that the eruption has already built an island of about 200 m diameter in size, which suggests that the vent was already located in very shallow waters.
A small steam and ash plume rising to about 2000 ft (600 m) was reported by VAAC Tokyo. The last known eruption of the volcano occurred in 1973 .
