Japan has released a report outlining safety measures for a possible eruption of Mount Fuji. While no eruption is imminent, scientists warn of serious risks.
According to experts, 490 million cubic meters of ash might be released during an eruption. The debris from the 2011 earthquake and tsunami is almost ten times this amount. The ash would primarily fall east of Mount Fuji, according to wind patterns. About 60 kilometers away, Sagamihara could observe 30 centimeters of ash. About 3 cm could be sent to Tokyo, Yokohama, and Kawasaki, with lower quantities perhaps making up to Fukushima.
Heavy ash fallouts may create difficulties in everyday life. Heavier layers can damage electrical networks, halt transportation, and topple buildings. Even 10 cm may make a vehicle immovable. Volcanic dust can infiltrate circuits and damage electronic devices. Experts also warn that ash can cause engine failure, posing risks to airplanes.
Historical Lessons
In 1707, after two years of earthquakes, Mount Fuji last erupted. Edo, which is now Tokyo, was covered in thick ash from the 16-day eruption. Famine resulted from the destruction of farmland. The debris caused several traditional wooden buildings to fall.
Authorities are nonetheless wary even though Mount Fuji is not active. Plans for evacuation and disaster maps have been made by local governments. It is recommended that residents accumulate necessities, such as food and medical supplies.
Takeshi Sagiya, a professor at Nagoya University, emphasized the difficulties in cleaning up. Volcanic ash cannot be easily disposed of like snow can. "Transport networks will be badly affected," he stated. Officials emphasize that reducing future dangers requires readiness.
