A new island has emerged off the coast of Iwo Jima, a volcanic island in the Pacific Ocean, making it the newest island in the world. According to the Japan Maritime Self-Defense Force, the island has not yet been named. The Japan Meteorological Agency explained to CNN that it was formed by an underwater volcanic eruption. The appearance of the island on the sea was captured in photographs taken by the Japan Maritime Self-Defense Force on the 1st of this month.

The series of photos show the eruption of a small-scale volcanic activity, with black smoke rising. The island is currently part of the Ogasawara Islands. Satsuya Nakata, a professor emeritus at the University of Tokyo, suggested to the Japan Times this week that magma that had accumulated underwater erupted to the surface.

The newly formed island is located approximately 1,200 kilometers south of mainland Japan, with a distance of about 1 kilometer from Iwo Jima. Iwo Jima was a major battleground during World War II, with US Marines engaging in combat with Japanese soldiers stationed on the island, resulting in over 7,000 American and more than 22,000 Japanese casualties.

On October 30th, Associate Professor Fukai Maeno from the University of Tokyo’s Earthquake Research Institute conducted an aerial observation of Iwo Jima and confirmed the occurrence of black smoke, containing rocks, rising to a height of over 50 meters at intervals of a few minutes, about 1 kilometer south of the island. The ejected rocks, some several meters in size, are believed to be a result of the “magma-water steam explosion” caused by the direct interaction of high-temperature magma with seawater.

Furthermore, it has been observed that a new island, approximately 100 meters in diameter and with a dark color, has formed just north of the smoke. According to Associate Professor Maeno, the surface of the new island is covered with rough rocks, indicating that it is likely formed by the accumulation of ejected rocks during the eruption. Although no crater has been confirmed on the new island, the presence of floating pumice and discolored seawater in the vicinity suggests the eruption of magma from this location. Associate Professor Maeno believes that at least two eruption points are occurring.

Experts suggest that the island may not last long as its crumbly formation is easily washed away by waves. However, they also point out that as long as the eruption continues, there is a possibility of the island expanding.

This new island off the coast of Iwo Jima is a reminder of the power of nature and the ever-changing landscape of our world. It is a reminder of the fragility of our planet and the importance of understanding and respecting the environment. It is also a reminder of the resilience of the human spirit, as Iwo Jima was a major battleground during World War II and a testament to the courage and strength of those who fought there.
