Japan: A new volcanic island that recently emerged in the Ogasawara chain far south of Tokyo has grown 10-fold during the past two months. The 3D stereoscopic images of Nishinoshima Island show that the volume of added rock above sea level has grown to 7.9 million cubic meters, about six times as large as the Tokyo Dome. The images were released by the Geospatial Information Authority of Japan (GSI). The GSI estimated the combined island landmass at 0.72 square kilometer, currently. The images are based on aerial photographs taken this year. The uninhabited isle, about 1,000 kilometers south of Tokyo, has merged with a new body of volcanic rock that was first spotted rising above the Pacific, last year. The rock has a maximum elevation of 66 meters up from 39 meters. Interactive stereoscopic images of Nishinoshima and its surrounding areas have been made available for view on GSI’s website.
