"Even if Mt. Fuji erupts, you have to stay at home."

Even if Mount Fuji erupts on a large scale, the Japanese government has established guidelines for behavior that basically recommend staying at home or in a safe place unless there is much volcanic ash falling.

The Japanese government decided on these guidelines because it is unlikely to become dangerous immediately even if volcanic ash falls, and many residents find it difficult to evacuate at the same time.

However, if there is a lot of volcanic ash falling on the ground, we decided to recommend evacuation.

Specifically, the thickness of volcanic ash accumulated on the ground is 3 to 30 cm, and if volcanic ash is expected to increase further, we will evacuate to a safe place depending on the situation.

In addition, if the thickness of the volcanic ash exceeds 30 cm, wooden houses could collapse, so we tried to get out of the area.

Mount Fuji, which is 3,776 m high, has erupted more than 180 times in the past 5,600 years, 96% of which were not large, with the last confirmed eruption in 1707.
