The Top 10 Largest Nuclear Explosions, Visualized
Just how powerful are nuclear explosions?
The U.S.’ Trinity test in 1945, the first-ever nuclear detonation, released around 19 kilotons of explosive energy. The explosion instantly vaporized the tower it stood on and turned the surrounding sand into green glass, before sending a powerful heatwave across the desert.
As the Cold War escalated in the years after WWII, the U.S. and the Soviet Union tested bombs that were at least 500 times greater in explosive power. This infographic visually compares the 10 largest nuclear explosions in history.
The Anatomy of a Nuclear Explosion
After exploding, nuclear bombs create giant fireballs that generate a blinding flash and a searing heatwave. The fireball engulfs the surrounding air, getting larger as it rises like a hot air balloon.
As the fireball and heated air rise, they are flattened by cooler, denser air high up in the atmosphere, creating the mushroom “cap” structure. At the base of the cloud, the fireball causes physical destruction by sending a shockwave moving outwards at thousands of miles an hour.
A strong updraft of air and dirt particles through the center of the cloud forms the “stem” of the mushroom cloud. In most atomic explosions, changing atmospheric pressure and water condensation create rings that surround the cloud, also known as Wilson clouds.
Over time, the mushroom cloud dissipates. However, it leaves behind radioactive fallout in the form of nuclear particles, debris, dust, and ash, causing lasting damage to the local environment. Because the particles are lightweight, global wind patterns often distribute them far beyond the place of detonation.
With this context in mind, here’s a look at the 10 largest nuclear explosions.
#10: Ivy Mike (1952)
In 1952, the U.S. detonated the Mike device—the first-ever hydrogen bomb—as part of Operation Ivy. Hydrogen bombs rely on nuclear fusion to amplify their explosions, producing much more explosive energy than atomic bombs that use nuclear fission.
Weighing 140,000 pounds (63,500kg), the Ivy Mike test generated a yield of 10,400 kilotons, equivalent to the explosive power of 10.4 million tons of TNT. The explosion was 700 times more powerful than Little Boy, the bomb dropped on Hiroshima in 1945.
#9: Castle Romeo (1954)
Castle Romeo was part of the Operation Castle series of U.S. nuclear tests taking place on the Marshall Islands. Shockingly, the U.S. was running out of islands to conduct tests, making Romeo the first-ever test conducted on a barge in the ocean.
At 11,000 kilotons, the test produced more than double its predicted explosive energy of 4,000 kilotons. Its fireball, as seen below, is one of the most iconic images ever captured of a nuclear explosion.
#8: Soviet Test #123 (1961)
Test #123 was one of the 57 tests conducted by the Soviet Union in 1961. Most of these tests were conducted on the Novaya Zemlya archipelago in Northwestern Russia. The bomb yielded 12,500 kilotons of explosive energy, enough to vaporize everything within a 2.1 mile (3.5km) radius.
#7: Castle Yankee (1954)
Castle Yankee was the fifth test in Operation Castle. The explosion marked the second-most powerful nuclear test by the U.S.
It yielded 13,500 kilotons, much higher than the predicted yield of up to 10,000 kilotons. Within four days of the blast, its fallout reached Mexico City, roughly 7,100 miles (11,400km) away.
#6: Castle Bravo (1954)
Castle Bravo, the first of the Castle Operation series, accidentally became the most powerful nuclear bomb tested by the U.S.
Due to a design error, the explosive energy from the bomb reached 15,000 kilotons, two and a half times what was expected. The mushroom cloud climbed up to roughly 25 miles (40km).
As a result of the test, an area of 7,000 square miles was contaminated, and inhabitants of nearby atolls were exposed to high levels of radioactive fallout. Traces of the blast were found in Australia, India, Japan, and Europe.
#5, #4, #3: Soviet Tests #173, #174, #147 (1962)
In 1962, the Soviet Union conducted 78 nuclear tests, three of which produced the fifth, fourth, and third-most powerful explosions in history. Tests #173, #174, and #147 each yielded around 20,000 kilotons. Due to the absolute secrecy of these tests, no photos or videos have been released.
#2: Soviet Test #219 (1962)
Test #219 was an atmospheric nuclear test carried out using an intercontinental ballistic missile (ICBM), with the bomb exploding at a height of 2.3 miles (3.8km) above sea level. It was the second-most powerful nuclear explosion, with a yield of 24,200 kilotons and a destructive radius of ~25 miles (41km).
#1: Tsar Bomba (1961)
Tsar Bomba, also called Big Ivan, needed a specially designed plane because it was too heavy to carry on conventional aircraft. The bomb was attached to a giant parachute to give the plane time to fly away.
The explosion, yielding 50,000 kilotons, obliterated an abandoned village 34 miles (55km) away and generated a 5.0-5.25 magnitude earthquake in the surrounding region. Initially, it was designed as a 100,000 kiloton bomb, but its yield was cut to half its potential by the Soviet Union. Tsar Bomba’s mushroom cloud breached through the stratosphere to reach a height of over 37 miles (60km), roughly six times the flying height of commercial aircraft.
The two bombs dropped on Hiroshima and Nagasaki had devastating consequences, and their explosive yields were only a fraction of the 10 largest explosions. The power of modern nuclear weapons makes their scale of destruction truly unfathomable, and as history suggests, the outcomes can be unpredictable.

This chart shows the top ten best selling video games, ranked by software units sold. Six of them have been released in the last 12 years.
Ranked: The Best Selling Video Games in History
It’s a good time to be a video game fan. Not only is the gaming industry booming and projected to grow to $320 billion by 2026, but every year is bringing new evolutions in the medium.
2022 saw massive launches in both games (Elden Ring and God of War Ragnarök) and media based on games (the films Uncharted and Sonic the Hedgehog 2). 2023 has already seen the release of major flagship TV series based on a game, HBO’s The Last of Us, and the much-anticipated The Super Mario Bros. Movie is slated to release in April.
But which game is the best, or most successful? That debate may never end, but from company reports and sales data aggregated by Wikipedia, Samuel Parker’s chart of the most-sold video games as of March 3, 2023 can at least tell us which ones have been the most popular.
Top Ten Video Games Sold in History
The best selling video game didn’t need multimillion dollar budgets, sixty-hour narratives, or celebrity voice actors and ad spots. The independently-developed (indie) Minecraft, with its pixelated blocks, takes the top spot on this list.
|Rank||Game||Sales (units)||Year Released||Developer|
|3||Tetris (EA)||100.0M||2006||EA Mobile|
|5||PUBG: Battlegrounds||75.0M||2017||PUBG Corp|
|6||Mario Kart 8||60.5M||2014||Nintendo|
|7||Super Mario Bros.||58.0M||1985||Nintendo|
|8||Read Dead Redemption 2||50.0M||2018||Rockstar|
Minecraft sold more units than the combined forces of Grand Theft Auto 5 (#2) and Red Dead Redemption 2 (#8), both made by industry giant Rockstar. Its immense popularity has been credited to its simple gameplay (no goals), creative structure (build anything), and engaged community with player-run servers and additional feature creations (known as mods).
Another simple favorite, Tetris, comes in at third place with 100 million units sold of its 2006 re-release. Millennials continue to make up a large chunk of the video game playing demographic which might explain Tetris’ sales.
But newer games are making up the majority of sales records. PUBG: Battlegrounds, a battle-royale shooter game which helped popularize the genre (and eventually its competitor Fortnite) asserts its popularity at #5. That puts it well ahead of the better-known shooter Call of Duty, even despite PUBG being banned in a number of countries for the alleged impact on the mental health of gamers.
The oldest game to make the list is Super Mario Bros. (#7), apt considering it is credited with reviving the video game industry after it crashed in 1983. The original staple side-scroller has sold 58 million copies worldwide.
Though the top selling games span various series of games, a few developers managed to repeatedly find success.
|Developer||Top 20 Best-Selling Games|
Japanese video game titan Nintendo developed three games (Super Mario Bros., Mario Kart, Wii Sport/Fitness) in the top 10 and another eight in the top 20. That’s not including its co-ownership of Pokémon, the world’s highest-grossing media franchise.
American publisher Rockstar Games also managed to score multiple hits, though its longer development cycle necessary to create cinematic games gives it fewer potential candidates. That might change with the much-anticipated GTA 6 reportedly in production.
Best Selling Genres
The most popular genres in the top 10 give players the freedom to impose their will upon the world and pursue objectives at their leisure:
Two games (Minecraft, Terraria) are classic sandbox games, where worlds are procedurally generated and there are no gameplay goals. Another two (GTA 5, Red Dead Redemption 2) are in the adjacent open-world genre, with a combination of sandbox elements and a narrative structure.
However, with new games launching and selling millions of units every year, new entrants to the top 10 list of best selling video games of all-time seems likely. How will these developers, genres, and games fare over time?
