Tokyo city was lit up at sunset

An AI-generated video released by the Tokyo Metropolitan Government shows the impact of Fujino's major volcanic eruption on the city's infrastructure. The simulation, part of Disaster Preparation Week, is based on a previous eruption of an active layer 3,776 meters high.
Common dangers associated with volcanoes are of slight concern as Mount Fuji is about 100 kilometers (60 miles) away from central Tokyo, and does not pose an immediate danger. Lava produced by formations are usually highly viscous and travels only short distances, and thermal clastic flows (avalanche of hot gas and debris) can kill people up to 10km to 20km (6-12 miles).
As shown in the video, the main risk is a thick layer of wind-infused volcanic ash to the city, paralyzing transport, disrupt communications and power grids, causing respiratory problems.
Currently there are no signs of Mount Fuji showing anxiety or increased volcanic activity. “The simulation is designed to equip residents with the precise knowledge and preparatory measures that can be taken in the event of an emergency,” the authorities explained.
The video concludes with the message “We need to arm ourselves with facts and prepare ourselves for disasters in our daily lives,” and instructs people to keep canned food, water, torches, first aid kits and other basic supplies at home.
The last historic eruption of Mt. Fuji began in December 1707 and continued until January 1708, when lava and ash erupted from a crater on the side of the mountain southeastern side. This eruption is well known for the immeasurable fall of ash produced in eastern Japan. The Tokyo area is covered with 2-8cm of ash, killing most plants in the field, slamming the rivers, spreading into hunger.
A similar eruption today could affect more than 30 million people in eastern Tokyo, kanagawa, chili peppers, mountain anashi and some of the more populated regions of Kenguku Prefecture.
Mount Fuji has over 20 seismic activity stations that monitor ground movement. It is impossible to determine when the next eruption will occur, but there may be signs such as earthquakes, ground deformation, and changes in gas emissions prior to the main eruption.
