The video discusses the top 10 most powerful explosions in human history, with a focus on nuclear tests. The ranking includes:
1. Tsar Bomb (USSR, 1961): 50-55 megatons
2. Test 219 (USSR, 1962): 24.2 megatons
3. Tests 173, 174, and 147 (USSR, 1962): 20 megatons each
4. Castle Bravo (USA, 1954): 15 megatons
5. Castle Romeo (USA, 1954): 13.5 megatons
6. Test 123 (USSR, 1961): 12.5 megatons
7. Castle Romeo (USA, 1954): 11 megatons
8. Mike (USA, 1952): 10.4 megatons
9. Tests 158 and 168 (USSR, 1962): 10 megatons each
10. Hardtack I (USA, 1958): 9.3 megatons
These tests were conducted by the United States and the Soviet Union during the Cold War era, and most of them took place in remote locations such as the Bikini Atoll and the Novaya Zemlya archipelago. The video also mentions that due to international treaties, these types of tests are now largely extinct, with North Korea being the only country that still conducts nuclear tests.
Here are the key facts extracted from the text:
1. The most powerful American nuclear test, Operation Hardtack I, was carried out on July 12, 1958.
2. The test released an energy of 9.3 megatons, equivalent to 9.3 million tons of TNT or 465 atomic bombs like those of Hiroshima and Nagasaki.
3. The test was carried out from a barge located on the Bikini Atoll of the Marshall Islands.
4. The Bikini Atoll was declared permanently uninhabitable by human beings in 1997 due to its radiological condition.
5. The US military carried out 23 nuclear tests in the Bikini Atoll between 1946 and 1958.
6. The Soviet Union carried out nuclear tests on the Novaya Zemlya archipelago in 1962.
7. The tests, numbers 158 and 168, released an energy of 10 megatons each.
8. The first hydrogen bomb was detonated on October 31, 1952, in the Enewetak Atoll by the United States.
9. The bomb, named "Mike," had a total power of 10.4 megatons and vaporized the small island of Elugelab.
10. The Castle Romeo test, carried out on March 27, 1954, had a power of 11 megatons and incinerated everything within a radius of 1.26 kilometers.
11. The test was carried out on the Bikini Atoll using a thermonuclear bomb.
12. Test 123, carried out by the Soviet Union on October 23, 1961, had a power of 12.5 megatons and incinerated any object within a radius of 1.32 kilometers.
13. The test was carried out on the Novaya Zemlya archipelago.
14. The Castle Bravo test, carried out on March 1, 1954, had a power of 15 megatons and released a cloud more than 35 kilometers high.
15. The test was carried out on the Bikini Atoll and spread radioactive waste over an area of 11,000 square kilometers.
16. The radioactive waste accidentally reached inhabited areas near the Bikini Atoll and was detected in Australia, India, Japan, Europe, and the USA.
17. The Soviet Union carried out tests 173, 174, and 147 on the uninhabited archipelago of Nuevas Femas from August 5 to September 27, 1962.
18. Each test had a power of 20 megatons and incinerated any object within a radius of 1.57 kilometers.
19. Test 219, carried out by the Soviet Union on December 24, 1962, had a power of 24.2 megatons and incinerated any object within a radius of 1.7 kilometers.
20. The test was carried out on the Nuevas Femas archipelago and is the most powerful detonation of a nuclear missile in history.
21. The Tsar Bomb, detonated on October 30, 1961, had a power of 50-55 megatons and is the largest explosion of human origin in history.
22. The bomb was originally designed to release 100 megatons of energy but was modified to reduce nuclear contamination.
23. The explosion was equivalent to detonating 3,000 atomic bombs at the same time and generated a cloud more than 65 kilometers high.
24. The explosion caused third-degree burns to any human being within 100 km of the explosion and broke windows at a distance of more than 900 kilometers.
25. The Soviet Union finished its nuclear tests in 1990, the United States in 1992, China and France in 1996, and India and Pakistan in 1998.
26. North Korea is the only country that still tests its nuclear weapons, with the last one exploding in 2017.
