A viral video created with synthetic intelligence (AI) reveals the catastrophic impression {that a} volcanic eruption at Mount Fuji may have on Tokyo, Japan, and its 37 million inhabitants. Happily, the informational video is just not timed to any elevated threat of an eruption — it is merely a public service announcement tied to Japan’s Volcanic Catastrophe Preparedness Day 2025.
The AI-generated video, launched Aug. 22 by the Tokyo Metropolitan Authorities, warns of the pace with which volcanic ash may journey from the volcano to Japan’s capital metropolis earlier than raining down on its roads, buildings, railways and different infrastructure. Clouds of particles from Mount Fuji may attain Tokyo in only one to 2 hours, subtitles beneath the video learn, paralyzing the town’s transport networks, reducing energy provides and affecting the respiratory well being of hundreds of thousands of individuals.
“The second might arrive with none warning,” the subtitles, translating the video’s narration from Japanese to English, say. “If Mt. Fuji erupted, volcanic ash might fall on Tokyo and impression us in all kinds of the way.”
Within the video, a lady receives an alert on her telephone warning of an eruption at Mount Fuji, which is situated 60 miles (100 kilometers) southwest of Tokyo’s metropolis middle. The clip then takes the viewer on an AI-generated tour of the potential impacts of volcanic ash on Tokyo’s transport hyperlinks, energy traces, water provides, residential buildings and inhabitants.
“It solely takes a minimal accumulation of ash on runways and rails to render planes and trains unusable,” the subtitles within the part of the video about transport infrastructure say. “A small quantity of ash on roads might impression the operation of 2WD [two-wheel drive] autos, because the ash fall limits visibility and will increase the chance of slippage, creating hazardous driving circumstances.”
Giant quantities of ash might block Tokyo’s sewers, contaminate freshwater provides, crush energy traces and collapse wood roofs, in accordance with the video. Town is also plunged into darkness as ash particles block the solar, and entry to meals and different necessities could also be briefly suspended. Moreover, folks may endure antagonistic well being results from inhaling the particles, with pre-exiting respiratory circumstances worsening with publicity.

Mount Fuji is Japan’s highest peak, measuring 12,389 ft (3,776 meters) tall. The final time the volcano erupted was in 1707, and the next ashfall lasted for 2 weeks, in accordance with the video. Whereas Mount Fuji used to erupt about each 30 years, it has now been dormant for 318 years, however some consultants assume that it may blow at any second.
Nonetheless, the timing of the video is unrelated to any indicators of an eruption, and there’s no suggestion that Mount Fuji is near exploding, the Tokyo Metropolitan Authorities stated in an announcement seen by CNN. “The simulation is designed to equip residents with correct information and preparedness measures they’ll soak up case of an emergency,” authorities officers wrote within the assertion.
Preparedness measures embody stocking up on meals and first help provides. Within the video, mother and father present their youngster a pantry full of canned meals, water and medicines prepared in case of an emergency.
The video was launched for Volcanic Catastrophe Preparedness Day 2025, however this is not the primary time Tokyo’s authorities has warned of the chance from Mount Fuji, in accordance with CNN. In March, officers printed pointers recommending that individuals inventory two weeks’ value of important provides of their houses always.
The Japanese authorities has been modeling earthquake and volcanic eruption eventualities for years, but these investigations don’t coincide with particular dangers from Mount Fuji or different geological options, Naoya Sekiya, a professor and threat communication skilled on the College of Tokyo, instructed NBC Information.
“There is no specific significance to the timing,” Sekiya confirmed.
Japan is dwelling to 111 energetic volcanoes — about one-tenth of the world’s whole — as a consequence of its place on the Pacific Ring of Hearth, a horseshoe-shaped belt of volcanoes across the Pacific Ocean. The nation is situated on the border between 4 tectonic plates that grind in opposition to one another and sometimes collide, triggering swarms of earthquakes and volcanic eruptions.
Maybe the perfect recognized pure catastrophe to strike Japan was the Tohoku earthquake and tsunami in 2011. The magnitude 9 earthquake was the strongest in Japan’s recorded historical past, with warnings going out to Tokyo residents only one minute earlier than the shaking started.
