Japan Discovers New Island 10 Days After Undersea Volcano Eruption
Just 10 days after an undersea volcano erupted off the coast of Japan, a newly formed island has been discovered. The world’s newest island has appeared off the coast of Japan’s southern island chain, known as ‘Iwo Jima’ or ‘Island of Ioto’, behind an unnamed submarine volcano. The volcano began to erupt continuously on October 21, 2023, causing ash and volcanic rocks to gradually accumulate under the shallow seabed until it emerged as a new island.
Uncertainty Surrounds the Longevity of the New Island
Experts, including Mr. Yuji Usui from the Volcanology Division of the Japan Meteorological Agency (JMA), have revealed that the new island may not last very long. Usui stated that volcanic ash and rocks had piled up on the shallow sea floor, with the peak of the island appearing above the sea surface in early November. The island is approximately 100 meters in diameter and 20 meters above the sea.
Furthermore, Usui highlighted that volcanic activity near the new island is increasing, signaling a significant development in the area. Despite this, volcanic activity has subsided and the new island has begun to shrink in size. The easily eroded newly formed rock layers could lead to a shorter lifespan for the island, unlike volcanic rock deposits which could help it last longer.
History of New Island Formations from Volcanic Activity
This is not the first time a new island has emerged from undersea volcanic activity. In 2013, a new island called Nishinoshima emerged in the Pacific Ocean south of Tokyo. Similarly, in 2015, a new island appeared from a month-long underwater volcanic eruption off the coast of Tonga. These instances highlight the dynamic nature of volcanic activity.
The Global Perspective on Volcanic Activity
The Japan Meteorological Agency notes that there are approximately 1,500 active volcanoes worldwide, with 111 of them located in Japan. The country’s position on the boundary of the tectonic plates in the Ring of Fire contributes to the high concentration of active volcanoes in the region.
Japan has discovered a newly formed island, just 10 days after an undersea volcano erupted off the coast of the country 3 weeks ago.
CNN reports that the world’s newest island has appeared off the coast of Japan’s southern island chain. ‘Iwo Jima’, also known as ‘Island of Ioto’ behindAn unnamed submarine volcano It began to erupt continuously on October 21, 2023, causing after 10 days the ash and volcanic rocks to gradually disappear.

At the same time, experts revealed that this islandIt may not last very long. byMr. Yuji Usui, an analyst from the Volcanology Division of the Japan Meteorological Agency (JMA). He said volcanic ash and rocks had piled up on the shallow sea floor. Its peak appeared above the sea surface in early November. This created a new island about 100 meters in diameter and 20 meters above the sea.

Usui Mr Will detail that further Volcanic activity is increasing near Iwo Jima. And similar undersea volcanic eruptions have occurred over the past few years, but the establishment of new islands is like this.This is a significant development.

However, Usui said volcanic activity in the area has now subsided. And the new island began to shrink in size. Some fell becauseNewly formed rock layers are easily eroded by waves. They can last longer if they form from lava deposits. This is not volcanic rock.

In addition, in the past, in 2013, there was a case of a new island emerging from the eruption of an undersea volcano.Nishinoshima in the Pacific Ocean, south of Tokyo. There is also a small island. emerged from the seabed after a magnitude 7.7 earthquake struck Pakistan, and in 2015 a new island emerged from a month-long underwater volcanic eruption off the coast of Tonga.
