Underwater volcanic eruption generates island

MONDAY, August 23, 2021 10:04 a.m. – The eruption of the Fukutoku-Okanoba submarine volcano has caused the formation of a new island on August 13.


Japan is an archipelago consisting of more than 6,800 islands. However, since August 13, an island of land has recently been added to the list, following the eruption of the submarine volcano Fukutoku-Okanoba. It is located about 1,200 kilometers south of Tokyo, near the volcanic island of Iwo Jima. Very small, the diameter of the island is only one kilometer.

It was the new land mass She was revealed by the Japanese Coast Guard two days after her training. After the explosion, they reported seeing plumes of steam and gas stretching 15 kilometers into the sky. In addition, they also said that they saw pieces of pumice from the volcanic eruption floating 60 kilometers into the ocean. Then they discovered the new island in the form of a crescent.

according to Forbes, authorities suspect that the entire Fukutoku Okanoba caldera may rise above the water’s surface.

It will not stay…

However, the new discovery may not always be… In the past, other Japanese islands that came into existence in the same way eventually vanished due to erosion. Among other things, all the new islands that appeared in 1904, 1914 and 1986 all disappeared soon after, and the newest ones disappeared about two months after their creation due to erosion by waves and currents.

Scientists say that Get out of the new island It will be determined by its configuration. If they turn out to be ash and rock fragments, there’s a good chance they won’t survive the oceanic elements. But since the country’s meteorological agency suspects the eruption is still ongoing, it may then generate enough lava flow to create a more permanent land mass.
