On 6 August 2010, Hiroshima was bombed with the first war-time used nuclear weapon. On 15 August 2010, Nagasaki was hit.
The 65th anniversary went by with very little mention in the world press. It is interesting that it wasn't mentioned more... It is an important date to remember. Just how many people can be killed by one bomb in just ms. But it is even more important to think of the size of the blast compared to what is possible today.
Just to give an idea of the modern day weapons (average 50 Megaton) v. 13 kiloton for Nagasaki. Although both sides state that the warheads are smaller, they were 50 MT for the most of the cold war and could still be that size. The only blast that large was the "Tsar Bomba" which was detonated at 50% yield. It was actually about 57 Megatons of TNT equivalent...
There's a website created by CarlosLabs which can show the areas damaged by different weapons.
