A new land area created from volcanic activity in the Pacific Ocean has increased in size to about 0.7 square kilometers, equivalent to the grounds of Meiji Jingu shrine in the capital, the Japan Coast Guard has announced.
The new land area first formed as a tiny separate island and later merged with Nishinoshima island of the Ogasawara Islands, Tokyo. It has since grown to about 70 times its size since it was discovered about four months ago.
The volcanic activity there is still strong, and the island will continue to grow, the JCG said Tuesday.
The JCG found in an aerial survey Monday that the new part of Nishinoshima island has grown to measure 1,150 meters from east to west and 850 meters from north to south. It was about 100 meters from east to west and 200 meters from north to south when it was found as a separate island on Nov. 20.
Nishinoshima now has a land area about 15 times the size of Tokyo Dome.
