National ( ) A smouldering islet created by undersea volcanic eruptions off Japan’s Pacific coast has melded to a nearby island, the Japanese coast guard said Thursday. Officials overflying the new landmass said it had merged at two points with Nishino-shima, an uninhabited volcanic island in the Ogasawara (Bonin) chain, some 1,000 kilometers south of Tokyo.
Two craters on the islet have been erupting “at an interval of 30 seconds to one minute,” spewing brown smoke about 100 meters high, a coast guard statement said. Pale volcanic gas and ash-grey smoke are also oozing out. The islet was first spotted on Nov 20, some 200 meters from Nishino-shima. It is now sized about 450 meters from east to west and 500 meters from north to south, with ground space measuring about 0.15 square kilometers, the statement said. “The amount of volcanic smoke has apparently grown with a continuous flow of lava,” Tokyo Institute of Technology geology professor Kenji Nogami reported from the plane.

The treeline ecotone is the region between the continuous forest and the tundra. This ecotone is typically known for being composed of gymnosperms, thus these angiosperm treelines are intriguing.
Climatic, topographic and anthropogenic interactions along with disturbance regimes all play a role in the formation and persistence of treelines. The UN Seahorse in Japan! Geography and Map of Japan. Japan Geography. Carte du Japon.
