A new island has just been formed in the Pacific after a volcanic eruption in the waters of the island nation of Tonga.
A small island appeared in Japan's territorial waters after the volcano erupted, marking the first time this special phenomenon occurred after 30 years.
The Japanese Navy saw smoke rising about 1000km south of Tokyo on November 20 and the coast guard then confirmed a new island was born around Ogasawara Islands.
