A new island created by a continuing volcanic eruption off the coast of Iwo Jima in the Ogasawara Islands is seen in aerial footage taken by NHK to be expanding and approaching Iwo Jima. Experts accompanying the team pointed out that an interesting phenomenon is occurring where the deposition of erupted material and erosion by waves are competing, causing the shape of the island to change rapidly in a short period of time.
