This visualization shows all nuclear weapon explosions from 1945 to 1998. Astonishingly there were more than 2000 explosions. The huge scale of nuclear weapon tests is unknown to most people, but nevertheless has health and environment effects until today. Having awareness about these events might be important to prevent further tests on this scale. This prompted Isao Hashimoto to make an amazing video . This visualization aims to present the data in a more interactive form. So have fun exploring the data of nuclear weapon testing.

The data shows some interesting events in the history of the cold war. For example the Bilateral testing ban between 1958 and 1961, marked by no nuclear weapon explosions initiated by the USA or USSR. The explosion of the biggest nuclear weapon tested: the Zar Bomb in 1961. Also from the sixties onwards, countries seem to use mostly standardized bomb sizes for tests.
