The Japanese Cabinet Office has released a computer-generated video simulating the potential effects of a large-scale eruption of Mount Fuji. The simulation depicts extensive volcanic ash fallout reaching as far as Shinjuku, Tokyo, approximately 100 kilometers from the volcano, where ash accumulation could reach up to 10 centimeters, significantly reducing visibility and disrupting infrastructure including roads and railways. The video aims to raise public awareness about the risks and emphasize the importance of preparedness, including stockpiling essential supplies for at least two weeks and prioritizing home evacuation. The simulation also shows that lava could reach local communities near Mount Fuji within 45 minutes, highlighting the urgency of evacuation measures. This release coincides with Japan's Volcanic Disaster Prevention Day, underscoring the need for readiness against volcanic hazards. Separately, Mount Shinmoe in southwestern Japan erupted recently, producing a volcanic plume rising 5,500 meters above the crater, with authorities maintaining an alert level 3 due to risks of large volcanic bombs and ash fallout reaching areas including Minamikyushu City, Kagoshima Prefecture.
