Japan’s geographical narrative has been enriched once again with the emergence of a new island, adding to its already extensive archipelago. This natural phenomenon, a result of an underwater volcanic eruption near the Ogasawara island chain, occurred in late October 2023. The eruption led to the formation of a new island, roughly 100 meters in diameter, through a process known as phreatomagmatic eruptions. These eruptions, characterized by the interaction of magma with seawater, produce explosive releases of ash and steam, creating new landmasses in the process. The phenomenon started near Iwoto Island, an area steeped in historical significance due to its role in World War II, and known historically as Iwo Jima. The island’s formation process was marked by a series of eruptions that lasted for about ten days, leading to the accumulation of volcanic material above the sea level.
