The largest nuclear explosion was the great âTsar Bombaâ. The bomb was tested on October 30, 1961, in Novaya Zemlya, an archipelago in the Arctic Sea. Originally planned to be 100 megatons, it was actually scaled down to 50 megatons due to technical problems with detonation and due to concerns with fallout.he explosion was equal to 1,400 times the combined power of the two atomic bombs used in WW2. It would have caused 3rd degree burns 62 miles away and the mushroom cloud was 7 times higher than Mount Everest. The explosion could be seen and felt in Finland.
