Codename #CastleBravo: Vor 70 Jahren explodierte auf dem Bikini-Atoll auf den #Marshallinseln eine thermonukleare Waffe - die Sprengkraft war 1000 Mal stärker als die der #Hiroshima-Bombe:  www.greenpeace.org/internationa... (1/4)

At this moment in 1954 at Bikini Atoll (6:45 AM March 1, local time), the US conducted its largest H-bomb test, Castle BRAVO (15 Megatons), which blasted a crater 1.23 miles wide and 250 feet deep.

Per @wellerstein.bsky.social, it was “the greatest single radiological disaster in American history.”
A screenshot from an official film showing an aerial view of the first milliseconds of the BRAVO explosion, an orange-red sphere of fire, the interior of which is almost impossibly bright (like the Sun). The shockwave on the surface of Bikini Lagoon as well as part of Namu Island itself is also visible.

Enfin, il s’inspire de l’affaire réelle du 01/03/1954, survenue dans le cadre d'une nouvelle série de tests américains d’armes atomiques (nom de code #CastleBravo) au cœur de l’atoll de Bikini du Pacifique Sud. À 145 km de l’explosion voguait le Dai-go Fukuryû Maru, un chalutier de pêche japonais..

It's Bikini Atoll vs. Bikini Bottom.

On the 1 March we mark #Nuclear #Victims Remembrance Day. The 1954 CastleBravo US nuclear test at Bikini Atoll in the #MarshallIslands didn't end in 1954. This day it is now marked by affected communities across the #Pacific and around the world. 👉 nucleartruthproject.org/nuclear-viol...
At the top of the image is black text on a cream background that says: This 1 March, We Remember Nuclear Victims Remembrance Day. Below the text is a photograph of the Runit Dome in Marshall Islands which is a repository for atomic waste that the U.S. produced during Cold War weapons testing. Below the photos the black text on cream reads: Nuclear Violence Has No Expiry Date. On 1 March we mark Nuclear Victims Remembrance Day (NVRD). The 1954 Castle Bravo test at Bikini Atoll didn't end in 1954. For the Marshallese people, the fallout - displacement, illness, contamination - continues today. NVRD is now observed by affected communities across Oceania and globally, a growing chorus of voices demanding accountability, truth, and justice for nuclear-affected peoples everywhere.

Today is the anniversary of the #CastleBravo #thermonuclear weapon test at #BikiniAtoll. The bomb was bigger than expected and the fishing vessel #DaigoFukuryumaru was caught up in its #fallout.

Can't be angry with people when no matter what we do, we can't effect change.

The system we have doesn't serve us. It only serves the 1%.
It's why we've passed climate tipping points and we're looking at cascades. We don't have the power to stop it as things stand.

CastleBravo @GraniteState19 I am at least heartened by the fact they were fooled by talk of peace. They voted thinking they were voting for peace but got war. Had they voted for war and got war then fuck them. But people wanting peace are still wanting that even if they were misguided and burned last time 2:57 AM · Jun 18, 2025 · 31 Views Babs 💙🐝⌛️🦋 @babs05.bsky.social Da’an (Earth Final Conflict) @p2tjzthwsq · 17h What is the chance of an actual candidate for peace of getting elected in the US?

1954: Castle Bravo—a miscalculation unleashes a 15-megaton blast, 1,000 times Hiroshima's. Radioactive ash descends like snow on inhabited islands, searing children playing outside. #CastleBravo #Fallout #NuclearDisaster

Der Film #Godzilla (1954) ist mehr als nur ein Monsterfilm – er ist eine Metapher für die atomare Bedrohung, inspiriert durch den Atomtest #CastleBravo und die Atombombenabwürfe auf #Hiroshima und #Nagasaki. Vor 70 Jahre war der Film in japanischen Kinos #OTD

In another act of colonial #EthnicCleansing/#genocide, the US forcibly displaced all #BikiniIslanders so their home could be used for #NuclearWeapons tests. On #ThisDayInHistory in 1954 the #CastleBravo test at #BikiniAtoll created America's worst radioactive contamination event.
