The new island emerged from the Pacific Ocean on 21st November 2013, south of the island of Nishino, in the Ogasawara archipelago, more than 1,000 km south of Tokyo.
The volcanic activity and expansion of this new territory were regularly monitored by the Pléiades satellites. The Geo-Intelligence experts at Airbus Defence and Space measured the growth of the island on three images taken over a two month period.
On the first image, taken on 30th November 2013, the island measured 35,200 m² just 9 days after it first appeared on the ocean’s surface. The crater is clearly visible, as is the turbidity in the surrounding waters.
The second image taken on 24th December 2013, shows the island had quadrupled in size in less than a month. With a surface area of now 155,652m² and was approaching the neighbouring island’s size of 223,402 m². The lava was only tens of metres from the southern beaches of the first island.
