Mushroom cloud western offshore of Japan

In the morning of 5/21/2014, explosive sound and a mushroom cloud were observed in Japanese western offshore.

The location was the north of Kumejima island. The residents felt the ground shaken with an explosive sound to find the mushroom cloud offshore.


There is Tori Shima Range of United States Air Force in 28 km north of Kumajima. The US armed forces states they held an air force training from 10:00 to 11:00 of 5/21/2014, but none of the details were announced.



You read this now because we’ve been surviving until today.

Un champignon dans le ciel au large du Japon


Au matin du 21 mai 2014, un bruit d’explosion et un nuage en champignon ont été remarqués au large des côtes ouest du Japon.
C’était au nord de l’île de Kumejima. Les habitants ont ressenti un tremblement du sol en même temps qu’ils entendaient l’explosion puis voyaient le nuage en champignon au large.

Il y a la base de Tori Shima Range des forces aériennes américaines à 28 km au nord de Kumajima. Les forces armées américaines affirment qu’elles ont procédé à un entraînement entre 10:00 et 11:00 ce 21 mai 2014 mais aucun détail n’en a été précisé.

Vous pouvez lire ceci parce que nous avons survécu jusqu’à aujourd’hui.

  1. The kind of effects strongly suggest a nuclear explosion, I fear, be it of weaponry or reactor (on board of some ship). 28 km is a very remote distance for ground-shaking effects by a conventional explosion, much more with all the buffering by the sea.

    1. Oh gods sake. The sea doesn’t ‘buffer’ explosions, water is almost incompressable and so is an excellent way to transmit shockwaves.

      Reactors do not produce nuclear explosions. They might experience a prompt-critical explosion where the reactivity creates a positive feedback chain reaction. In this case however, the energy released tends to make the reactor blow apart in a standard (non-nuclear) pressure-temperature explosion. In fact, it is extremely difficult to keep the fuel material together long enough for a substantial amount of the fuel to be converted to energy. This was the main objective of the manhatten project. You n ed to set off conventional explosive material in precisely shaped charges around the fuel so the shockwave from that holds the exploding fuel together long enough to cause a nuclear detonation. It simply does not happen by accident.

      Also, the fact that there is a mushroom shaped cloud doesn’t mean squat either. Most large explosions produce a mushroom cloud. Most nuclear explosions produce an emp which is detectable at long range, and someone probably would have noticed in this case.

      Most likely explanation is some kind of weapon test (non nuclear), or possibly an accident but they’d probably make h public statement if that were the case.

      1. The suggestion that the cloud could be from an explosion on a shipborne reactor is reasonable given its similarity to the mushroom cloud that went up from FD Reactor 3. However at this stage there are several more likely possibilities including conventional ordnance and volcanic eruption.

      2. Quote: “Reactors do not produce nuclear explosions.”

        Nice try. They can experience moderated prompt criticalities. We may have witnessed one such event.

  2. No radioactivity reported, in initial accounts

About this site

This website updates the latest news about the Fukushima nuclear plant and also archives the past news from 2011. Because it's always updated and added live, articles, categories and the tags are not necessarily fitted in the latest format.
I am the writer of this website. About page remains in 2014. This is because my memory about 311 was clearer than now, 2023, and I think it can have a historical value. Now I'm living in Romania with 3 cats as an independent data scientist.
Actually, nothing has progressed in the plant since 2011. We still don't even know what is going on inside. They must keep cooling the crippled reactors by water, but additionally groundwater keeps flowing into the reactor buildings from the broken parts. This is why highly contaminated water is always produced more than it can circulate. Tepco is planning to officially discharge this water to the Pacific but Tritium is still remaining in it. They dilute this with seawater so that it is legally safe, but scientifically the same amount of radioactive tritium is contained. They say it is safe to discharge, but none of them have drunk it.
