16 Maps That Show The Blast Radius Of Nuclear Bombs On Major Cities

When people think back on the devastating effect of dropping two atomic bombs on Japan in 1945, it’s hard to relate that to our own lives. The destructive forces unleashed are things we’ve never experienced with our own eyes and dramatizations of the effects are often met with skepticism. It’s just not something many of us can emotionally connect with properly, despite understanding the graveness of the attack. In Hiroshima and Nagasaki, the effects of the attacks were unprecedented.

  • Between 130,000-250,000 people were killed, including over 100,000 civilians.
  • Close to 40% of the cities’ structures were destroyed or severely damaged.

The bombs that were dropped in 1945 were called Fat Man and Little Boy”, and had a blast yield of 20 and 15-kilotons respectively. For comparison, the largest nuclear warhead ever tested was the Tsar Bomba in 1961, a 57-megaton yield (1570 times larger than the combined energy of FM and LB).

In an interactive map by Alex Wellerstein we may be able to gain a little bit of perspective over the destructive nature of these weapons. In the photos below, we’ve used a 50-megaton explosion. 

1. New York City, New York – When dropped in Lower Manhattan, the fireball radius alone stretches from Jersey City to Brooklyn. Third-degree radiation burns would affect people more than 37 miles away. Estimated fatalities would be well over 7 million.

2. Washington, DC – If the bomb was detonated on the White House, the building damage would almost reach Fairfax. With fatalities estimated over 2 million, the fireball would encompass everything from the Pentagon to Howard University.

3. London, England – Detonated over parliament, the blast would affect people all the way in Reading. With almost 6 million estimated fatalities, it would wipe out more than 10% of the English population.

4. Paris, France – A country that has been hit with several terrorist attacks in the last few years would see close to 7 million fatalities if Paris was hit. In comparison, France lost 210,000 soldiers in World War II.
