About Doha

The capital and largest city of Qatar.

Below are four scenario calculations using historical and modern nuclear weapons. Each row shows the radius of an effect zone in kilometers for an air burst at optimum height[2, 3]. Radii are scaling-law estimates — see the methodology page for the underlying relations. Casualty and fallout estimates are not shown pending a verified population and fallout model.

Tsar Bomba on Doha (50 Mt)

USSR · 1961 · Largest nuclear weapon ever tested

Effect zoneRadius (air burst)
Fireball4.62 km
Severe blast (20 psi)8.64 km
Moderate blast (5 psi)23.1 km
Light blast (1 psi)64.1 km
3rd-degree thermal burns54.1 km
2nd-degree thermal burns61.2 km

Limitations

These radii assume an idealized air burst at optimum height over the city center. The real extent of each effect depends on:

  • Burst height and whether the detonation is an air or surface burst
  • Terrain, building construction, and line of sight
  • Weather and atmospheric conditions
  • Distance from the detonation point within each zone

Casualty counts, fallout plumes, and radiation doses are not modeled on this page.

FAQ

What would happen if a nuclear bomb hit Doha?

Doha has a population of about 1,186,023 (2020, city proper) and an urban density around 8,985 per km². A Hiroshima-yield warhead (15 kt Little Boy), air-burst at optimum height, would produce a 5 psi moderate-blast radius of about 1.54 km — the zone in which typical homes and lightly built commercial buildings are destroyed. A modern strategic warhead (W76, 90 kt) would extend that moderate-damage zone to roughly 2.80 km, with 3rd-degree thermal burns reaching 4.57 km. Run the interactive simulator above to see the exact zones overlaid on the map.

What is the blast radius of a nuclear bomb over Doha?

For a 100 kt strategic warhead air-burst over Doha: fireball radius 0.37 km, severe blast (20 psi) 1.02 km, moderate blast (5 psi) 2.80 km, light blast (1 psi) 7.70 km, and 3rd-degree thermal burns 4.57 km. All radii assume an air burst at optimum height and scale with weapon yield.

How do different nuclear weapons compare over Doha?

The 1 psi light-blast radius — roughly the limit of shattered windows and light injuries — runs about 4.26 km for a 15 kt Little Boy versus about 64.1 km for the 50 Mt Tsar Bomba. Blast radius scales roughly with the cube root of yield, so a 3,000× larger weapon extends the radius only about 14×.

Is Doha a likely nuclear target?

This is an educational simulator and does not assess threat probability. Doha is one of the world's most prominent cities in Middle East, which is why we feature it as a scenario. The purpose of these visualizations is to convey the physical scale of nuclear weapons — not to make any operational claim.
