The ~14 minute-long video here-below gives us a visualized overview of all known nuclear explosions on our planet from 1945 onward to 2015. The indicator colors represent the nature of the explosion, i.e.
= atmospheric detonation
= subterranean detonation
= underwater detonation
Two things really stand out here...:
- Most of the nuclear detonations are conducted by -- and take place inside -- the United States of America.
- The Russian Tsar bomb, which was the most powerful human-contrived detonation ever on Earth since the beginning of nuclear weapons testing.
