On the occasion of Volcano Disaster Prevention Day, the Japanese government distributed a video that emphasizes the need for advance preparation by showing the damage situation with computer graphics (CG) assuming the eruption of Mount Fuji on the 26th.
The Japanese Cabinet Office estimated the extent of the damage by substituting the magnitude of the 1707 eruption in a video that lasted about 10 minutes.
According to the video, 20cm of volcanic ash was estimated to accumulate two days after the eruption in Sagamihara City, Kanagawa Prefecture, about 60km from Mount Fuji.
In Shinjuku Ward, Tokyo, 100 kilometers away, volcanic ash is expected to accumulate more than 5 centimeters in two days.
In the case of wooden houses, the house collapsed, saying that if volcanic ash builds up on the roof more than 30cm, it becomes dangerous due to its weight. He also introduced that it would be difficult to drive a car if it rained with more than 3cm of volcanic ash piled up.
Mount Fuji has erupted once every 30 years on average in the past, but it has been quiet for more than 300 years, said Toshitsu Fujii, an honorary professor at the University of Tokyo, a geoscientist, in a video.

This is not the first time experts have warned that Mount Fuji could explode immediately.
Earlier in 2022, Nagao Toshiyasu, a visiting professor at Tokai University’s Ocean Research Institute, said, “Earthquake activity has been active around Mount Fuji since December last year.
Mount Fuji has not erupted for 300 years, so there is a strong accumulation of power inside, he said. “100 out of 100 volcanologists agreed that it will erupt in the near future.”
Shimamura Hideki, a special professor at Musashinogakuin University, an expert in volcanology, said in December 2021, “The earthquake in eastern Yamanashi Prefecture on the morning of the 3rd was caused by the flow of magma from Mount Fuji. We can think of a volcanic eruption as approaching.”
He also added, “Even if only 0.5mm of volcanic ash accumulates in the metropolitan area, severe traffic will occur because the subway cannot move.”
Other experts also warned that Mt. Fuji will surely explode one day.
“The Fujisan observation system can detect precursors before the volcano erupts,” said Wada Tamakasa, disaster crisis management advisor. “We can determine the actual intensity of the eruption after the eruption.”
He warned, “It’s foolish to wait for the authorities to announce it,” adding, “It’s the way to live to run away unconditionally.”
Meanwhile, Mount Fuji’s recent eruption was on December 16, 1707, when volcanic ash began to fall in Tokyo two hours after the eruption and piled up to a thickness of 2cm over about two weeks.
