Nuclear Blast Scenarios
200 pre-computed bomb-on-city impact calculations. Each scenario page shows the fireball, blast zones, thermal radiation, and estimated casualties for a specific weapon over a specific city, using local population density and validated scaling-law formulas.
How this section is organized
Each scenario combines one of 10 featured nuclear weapons with one of 20 major cities. Below the table, you can also browse by weapon (every weapon's scenarios on every city) or by city (every weapon detonated on a single city).
For a more flexible experience use the interactive simulator — you can choose any weapon and any location worldwide and the calculations update live.
