Japan's government released an AI-generated video simulating a Mount Fuji eruption, warning Tokyo's 20 million residents of potential consequences. The video depicts volcanic ash blanketing the city within two hours, disrupting transport, power, and food supplies. While an eruption isn't imminent, Fuji is an active volcano, last erupting 318 years ago. The simulation highlights the potential for widespread chaos and significant economic losses, estimated at $16.6 billion. Authorities aim to increase preparedness, although some residents and experts express concerns about the alarmist tone.
