Regarding "Mt. Shirane" of Mt. Kusatsu-Shirane in Gunma Prefecture, the Japan Meteorological Agency canceled the warning around the crater this morning and lowered the eruption alert level from level 2 to level 1 "Note that it is an active volcano".
On top of that, we are calling for attention to the small-scale eruption of volcanic ash near the Yugama crater.
At "Mt. Shirane" on Mt. Kusatsu-Shirane in Gunma Prefecture, the Japan Meteorological Agency has set the eruption alert level from "1" as volcanic activity is increasing, such as an increase in volcanic earthquakes near Yugama three years ago in September (2018). I raised it to "2" and called for caution within a range of about 1 km from the Yugama crater.
Since then, ▽ volcanic earthquakes have been in a low state since late January, and ▽ volcanic tremors, which are thought to indicate the movement of underground hot water and volcanic gas, have been observed since December last year. It means that it is not.
For this reason, the Japan Meteorological Agency considers that the possibility of an eruption affecting a range of approximately 1 km is low, and today at 11:00 am, it is an "active volcano" with an eruption alert level of "2" to "1". Keep in mind ”.
On top of that, we are careful about small-scale volcanic ash eruptions and high-concentration volcanic gas within a range of about 500 meters from the crater, and we are urging people not to enter dangerous areas according to the instructions of the local government.
Regarding Mt. Kusatsu-Shirane, the Japan Meteorological Agency operates the eruption alert level by dividing it into "near the Yugama of Mt. Shirane" and "Mt. Motoshirane", and the eruption alert level of "Mt. Motoshirane" is currently "1". It has become.
