A new island about 1,000 km south of Tokyo has joined the neighboring island of Nishinoshima, the Japan Coast Guard said Thursday.
The distance between the two islets narrowed to some 10 meters as of Tuesday. The new islet, which first emerged as a spewing volcanic cone, is unlikely to be given a name as it will be regarded as part of Nishinoshima in the Ogasawara chain.
Aerial observations by the Coast Guard have revealed that the northwestern side of the new islet has joined with the south side of the Nishinoshima at two points. Between the points is a pool of murky seawater, according to the Coast Guard.
Volcanic fumes some 100 meters high are being emitted by a crater on the island. Kenji Nogami, a professor at Tokyo Institute of Technology’s Volcanic Fluid Research Center who took part in the observation, said the volcano is highly active, with fumes and lava continuing to increase in amount.
The Coast Guard confirmed the existence of the new islet on Nov. 20. Due to flowing lava, it had grown to 150,000 sq. meters of Tuesday from some 10,000 sq. meters on Nov. 21.
