Every nuclear explosion since 1945, on the map
The 2,057 nuclear explosions from 1945 to 2017: 2,055 tests by 8 states, and the 2 bombs of Hiroshima and Nagasaki, the only ones used in war. Sources: SIPRI (1945-1998) and USGS (North Korea).
Remember this
The peak came in 1962: 178 explosions. After the 1963 treaty, tests moved underground: 1,527 in all. The most powerful, Tsar Bomba (50 Mt, 1961), was over 3,000 times Hiroshima. Since 1998, only one country has tested, last in 2017.
