Nuclear blast radius by city

Last updated

These pages freeze one educational scenario over the dense core of a city. The rings and casualty counts are the same simplified model the globe uses. Open the simulator to move the burst, change weapons, or add fallout.

Educational estimate only. Blast and heat rings use simplified yield scaling. They ignore terrain, weather, shielding, and weapon design. Casualty counts use WorldPop 2020 residents on an approximately 1 km grid and ignore time of day, commuting, shelter, and evacuation. This is not a targeting or civil-defense tool. About the model.
