There is a new island eruption, magma overflows, and an undersea volcano erupts to form a new island
The newly popped islands can be seen from the coastline of Iwo Jima, about 1,000 kilometers (621 miles) south of the Ogasawara Islands in Japan's southern Pacific Ocean, the Shanghai Port Daily reported.
It was formed by an unnamed submarine volcano that began to erupt on October 21. By October 30, the magma reached the surface of the sea and accumulated in the form of a new island
"In the early stages, vertical jets of black jets, solidified magma, and water erupt upward. Since November 3, the state of the eruption has changed, and the volcanic ash has continued to erupt violently," Yukiya Nakata, professor emeritus of volcanology at the University of Tokyo, told the newspaper.
"Those areas where there is no magma can be wiped clean. If more magma gushes out and covers the area, that part will stay there forever. ”
With the eruption of underground submarine volcanoes, new islands often form in the world's oceans. Underwater volcanoes erupt molten material, which is quickly cooled by the seawater and solidified to form small hills that can jut out of the sea.
For example, another new island appeared as a result of a volcanic eruption under Fukutookanoba near Japan in August 2021.
Japan is part of the Ring of Fire Seismic Zone, a 40,000-kilometer (24,900-mile) region of the world that surrounds the Pacific Ocean and is home to two-thirds of the volcanoes that have been active since the last ice age.
This is one of the geological and geographical factors that explain why Japan has so many islands. Before 2023, it was thought that Japan had 6,852 islands. However, a recount carried out earlier this year showed that the total could be more than double that number, with a total of about 14,125 islands.
Maybe now they'd better change that number to 14,126
