Back in 1973, a volcanic eruption in the western Pacific ocean caused the formation of a new island named Nishino-shima. Four months ago, a nearby eruption caused the formation of a new island named Niijima. The Niijima eruption has continued and the island has been growing and has now consumed Nishino-shima and it is continuing to grow larger.
It’s quite a look at the birth of an island. From the NASA Earth Observatory site:
The Niijima portion of the island is now larger than the original Nishino-shima, and the merged island is slightly more than 1,000 meters across. Two cones have formed around the main vents and stand more than 60 meters above sea level, triple the highest point of the island in December. Volcanic lava flows are reported to be most active now on the south end of the island.
