• Japan releases AI simulations warning of potential hazards from a Mount Fuji eruption.
• Videos highlight risks to health, transportation, power supply, and logistics in Tokyo.
• The last eruption occurred in 1707, but Mount Fuji remains an active volcano.
• Authorities emphasize building public awareness and emergency preparedness plans.
• Critics describe the simulations as alarmist, while supporters call for preparedness.

The Japanese government has launched a series of AI-generated simulations depicting a catastrophic eruption of Mount Fuji, aiming to enhance disaster preparedness among the populace. Released to coincide with Volcano Disaster Preparedness Day, the videos illustrate a dramatic scenario where volcanic ash could cover Tokyo within hours, leading to severe disruptions in health, transportation, and power supplies for the city's 37 million residents. Despite the alarming visuals, officials emphasize that there are currently no indications of an imminent eruption, according to South China Morning Post, India Times, and Channel News Asia.

The simulation showcases scenarios where ash clouds could lead to significant health risks, such as respiratory issues among the population, and logistical breakdowns affecting food and basic supplies. Notably, the video dramatically portrays how just 3 cm of ash could paralyze Tokyo, impacting transportation and leading to widespread power outages. This proactive approach is part of Japan's broader strategy to prepare its citizens for potential disasters given its position on the Pacific Ring of Fire, which houses many active volcanoes, according to South China Morning Post and India Times.
