A viral video created with artificial intelligence (AI) shows the catastrophic impact that a volcanic eruption at Mount Fuji could have on Tokyo, Japan, and its 37 million inhabitants. Fortunately, the informational video is not timed to any increased risk of an eruption — it's merely a public service announcement tied to Japan’s Volcanic Disaster Preparedness Day 2025.
The AI-generated video, released Aug. 22 by the Tokyo Metropolitan Government, warns of the speed with which volcanic ash could travel from the volcano to Japan's capital city before raining down on its roads, buildings, railways and other infrastructure. Clouds of debris from Mount Fuji could reach Tokyo in just one to two hours, subtitles beneath the video read, paralyzing the city's transport networks, cutting power supplies and affecting the respiratory health of millions of people.
