23:17 on August 7 to protect yourself from a cinder
To protect yourself from cinders, it is important to evacuate to a sturdy building as far as possible from the crater.
Within a few kilometers from the crater, a “large cinder” with a diameter of 50 cm or more may fly, and in some cases, it may be as large as a car.
These cinders fly away from the crater without being affected by the wind, so they have the destructive power of breaking the roofs and walls of the building.
According to the Japan Meteorological Agency, the damage caused by these large cinders is limited to the range of 2 to 4 km from the crater.
On the other hand, even at a location about 10 km away from the crater, “small cinder” with a diameter of 2 mm or more is thrown on the wind, so care must be taken on the lee side.
In some cases, a fist size as large as a fist may fly, and if hit directly, there is a risk of injury.In addition, if the glass of a house or car is broken, or if it is a plastic roof, it will penetrate. There is also a possibility of end.
If you notice an eruption, it is important to evacuate inside the building or under a sturdy roof. Also, in order to make the glass difficult to break, measures such as putting blankets on the windshield and rear glass of cars are also effective.
