Japan’s government has recently issued a new set of guidelines for the Tokyo metropolitan area in response to the possible eruption of Mount Fuji. The iconic volcano, which has been dormant for over 300 years, could soon pose a serious threat to millions of residents living near Japan’s capital. With Mount Fuji’s eruption a real possibility, the government has urged Tokyo residents to prepare for potential volcanic ashfall that could disrupt daily life on an unprecedented scale.
A Long-Awaited Warning: What to Expect in Case of Eruption
The guidelines, developed by an expert panel, categorize the expected severity of the eruption’s fallout into four stages. Ashfall could range from mild dustings to dangerous accumulations exceeding 30 centimeters in some areas.
Should the ashfall reach the highest stage, the Tokyo metropolitan area may face significant disruption. In the event of such a severe eruption, residents living in wooden houses, or near buildings that could collapse under the weight of ash, are advised to evacuate, particularly if the ash accumulation exceeds 30 centimeters.
Health and Safety Risks: How to Stay Protected
For those who remain indoors, the guidelines emphasize taking precautions against the health risks posed by volcanic ash. Prolonged exposure can lead to eye irritation, breathing difficulties, and throat discomfort.
Residents are strongly encouraged to stay inside, avoid unnecessary travel, and wear masks and goggles if they must leave their homes. People with respiratory conditions, such as asthma, are advised to take even greater care to limit exposure to the harmful effects of ash.
Driving in these conditions is strongly discouraged due to the reduced visibility caused by falling ash. Additionally, residents are encouraged to stockpile emergency supplies, including food, water, and essential medications, in preparation for potential service disruptions, which could last for extended periods, as seen in the eruption of 1707.
Disaster Preparedness: A Key Focus for the Government
The Japanese government’s response plan also addresses the need for preparedness beyond immediate safety measures. The expert panel warns that a major eruption could result in interruptions to vital services, such as electricity, water, and mobile communication.
The government is already planning the logistics for ash removal and disposal, exploring methods such as using the ash as a construction resource or safely disposing of it in landfills or the ocean. These efforts aim to prevent overwhelming the city’s infrastructure in the event of a significant eruption.
Ahead of any potential eruption, the government stresses the importance of educating the public about the risks of volcanic ashfall and how to respond effectively. The panel also recommends further training for disaster relief specialists who will be critical in managing the aftermath of such an event.
