"Undersea Volcanic Eruption Forms Temporary New Island off Japan's Coast"

An undersea volcano off the coast of Iwo Jima, Japan, erupted three weeks ago, resulting in the formation of a new island. The island, about 100 meters in diameter and 20 meters high, was created by volcanic ash and rocks piling up on the seabed. However, experts believe the island may not last long due to its crumbly formation, which is easily eroded by waves. Japan, located in the Pacific Ring of Fire, has 111 active volcanoes.
