Nishinoshima in the Ogasawara Islands where active eruption continues. Satellite observations revealed that the south side of the island had expanded by up to 150 meters in two weeks until the 3rd.

On Nishinoshima, active eruption activity continued after mid June, and the observation by the Japan Coast Guard on June 29 confirmed that hot magma was continuously ejected.

The Geospatial Information Authority of Japan used the observation data of the Earth observation satellite "Daichi 2" to compare the state of 3 days and the state of June 19 which is two weeks ago, and the south side of the island expanded by up to 150 meters. I understood that it was.

Furthermore, it was found that the diameter of the "pyroclastic cone" in the central part of the island, which was covered with volcanic ash, was about 1.5 times larger, and the slope on the south side collapsed significantly.

Kenji Nogami of Tokyo Institute of Technology, who is familiar with the volcanic activity of Nishinoshima, says, "In Nishinoshima, it seems that a large amount of magma is supplied from underground, and there is a possibility that lava will continue to flow in the future." ..
