A volcanic eruption occurred at 9:08 pm on August 7 at the junction of Nagano Prefecture and Gunma Prefecture in Japan. The Meteorological Agency announced that it would raise the volcanic alert level within a 4km radius of the crater to a level 3 alert level, alerting the public that there may be a large risk of blasting and volcanic debris flow.
The Japan Meteorological Agency pointed out that the volcanic eruption was more than 1,800 meters, and the volcanic ash was drifting to the north. It was the second time since June 2015 that the shallow mountain broke out.
The Japan Meteorological Agency has called for attention to future volcanic activity. The footage recorded by the Japan Broadcasting Association (NHK) shows that the crater area emits red light when the volcano erupts, and a large amount of ash rushes into the sky.
In addition, the authorities have released the “Gray Reduction Forecast” for the Gunma Prefecture, Nogawaramachi, Yuki-mura, Nagano Karuizawa, and Oyado-machi. It is expected that there will be a small amount of volcanic ash falling in the early morning of the 8th.
