🌋⚠️ MOUNT FUJI ERUPTION SCENARIO — JAPAN’S NEW SIMULATIONS ⚠️🌋
Japan has released new official simulations of what a major eruption of Mount Fuji could look like.
👉 Important: This is NOT a prediction.
Mt. Fuji remains at Alert Level 1 — the lowest.
The release marks Volcano Disaster Prevention Day (Aug 26).
📊 What the Simulations Show
🔹 Ashfall — 2–10 cm may blanket Tokyo & the wider Kanto region.
🔹 Clean-up crisis — ~120 million m³ ash in Tokyo, ~4.9 billion m³ total — over 10× the disaster waste from the 2011 Great East Japan Earthquake.
🔹 Infrastructure hit — Power, water, telecoms, roadways & rail transport could be paralyzed. Airports & Shinkansen likely shut down.
🔹 Health impact — Fine ash dangerous for lungs, eyes & machinery.
🧭 Govt Guidance
— 🚪 Stay home in most areas.
— 🏚️ Evacuate only if ash >30 cm (roof collapse risk).
— 😷 Stockpile masks, food, water for days of disruption.
— 🌐 Tokyo Gov has launched a special “Fuji Ashfall” site (English available).
📌 Fuji’s Current Status
✅ Alert Level 1 — “Active volcano: be aware” (Japan Meteorological Agency).
✅ No abnormal seismic or volcanic activity reported.
✅ Last eruption: 1707 (Hōei eruption).
🌍 Why Now?
Tokyo = 37 million people. Even a small eruption could paralyze the world’s largest urban area.
These simulations are about awareness & preparedness — not alarm.
⚠️ Bottom Line:
There’s no current eruption warning.
Japan is preparing so people understand the potential scale of impacts.
