Undersea Volcano Creates Ephemeral New Island near Japan

An undersea volcano off the coast of Japan has erupted, resulting in the formation of a new island. The island, located near Iwo Jima, emerged within 10 days and reached a diameter of 100 meters and a height of 20 meters. However, experts believe that the island may not last long due to its crumbly formation, which is easily eroded by waves. The volcanic activity has subsided, and further analysis is being conducted to determine the island's composition. Japan, situated on the Pacific "ring of fire," has 111 active volcanoes.
