Japan's Maritime Self-Defense Force documented the event, and the eruption has been linked to ongoing volcanic activity in the region.
Nature is beyond the understanding of humans. Every time people make the mistake of thinking they are the masters of the world, nature jolts them down and brings them to the ground. Recently, Japan shocked the world when its sea formed a new island, per CNN. The visual of the new island was a sight to behold and captured the entire world's attention. Till now, the authorities have not concluded the name of the island. They are focused on understanding its origin from the sea and its further development in the location.
Already aware of its eruption, the country's Maritime Self-Defense Force was on site to document the island's rise on November 1. The eruption occurred on the Japanese island of Iwoto. The photos feature a small eruption, with a dark ash cloud, right above the island. As per Japan's Meteorological Agency (JMA), the island has become a part of the Ogasawara Islands chain. Even prior to the eruption, the area witnessed a lot of volcanic activity for the entire last year. Though there were a lot of speculations, the confirmation about the island only came on October 30.
The island is just a kilometer apart from Iwoto, per The Guardian. It hosts an active volcano and holds a lot of historical importance for Japan. It is where one of the bloodiest battles in the country's history happened. According to the National WWII Museum, 6,821 Japanese soldiers were killed in the Pacific War. In the past, the location was known as Iwo Jima, but the authorities renamed it in 2007. Volcanic activity is not unknown in this area. Similar eruptions were noticed between July and December of last year and in June this year.
The island was formed due to an undersea volcanic eruption. As per the experts, the eruption started in October around Iwoto island, part of the Ogasawara island chain in the western Pacific. It attracted the attention of Fukashi Maeno, an associate professor at Tokyo University's earthquake research institute. He analyzed the eruption and concluded that the eruptions were photomagnetic. It meant that they came into being because of the interaction between magma and water. This eruption then led to a landmass measuring 100 meters in diameter.
Maeno himself monitored the volcano when the island came out of the sea. He informed the Kyodo news agency that smoke and ash were on full display during the process. Large rocks were also hurling out of the air and bands of brown pumice stones floating in the sea. Maeno shared that this island proves that magmatic activity has returned to this area. As far as the future of the island is concerned, he believes that as of now, there is no definite path for it.
It can end up growing larger and changing shape due to the eruptions or it could also disappear within the waves. This site has witnessed islands being formed in such a way in 1904, 1914, and 1986, and all of them suffered the same fate. They all disappeared as a result of erosion. New islands just have ash and rock fragments in their structure, which struggle against waves. It needs constant volcanic activity to become harder and more resistant.
