According to JMA (Japan Meteorological Agency), Mt. Hakone erupted around the noon of 7/21/2015.

The newly created crater emitted gray volcanic fumes up to 50m height above the ground to contain volcanic ash.

JMA announced “it was a very short phenomenon and a little bit of volcanic ash was contained”, but did not report any quantitative data. The emitted volcanic ash was not officially collected to measure how far it flew. They did not explain why either.

No official announcement on this eruption is posted on the front page of their website.

They state it was an eruption but they don’t find it appropriate to call it an eruption otherwise it may inflame public anxiety.


It is only 80km from Mt. Hakone to the center of Tokyo.

Éruption du Mt. Hakone / JMA : “ne pas dire éruption pour ne pas affoler” / c’est à 80 km de Tokyo

Photo : Le Mt. Hakone enregistré par la caméra de direct de la JMA. La vue n’est absolument pas claire et on n’y voit pas la montagne. L’objectif est maculé de cendres blanches mais la JMA n’affirme pas officiellement qu’il s’agit de cendres volcaniques.

Selon la JMA (Japan Meteorological Agency), le Mt. Hakone est entré en éruption le 21 juillet 2015 vers midi.

Le nouveau cratère formé a émis des fumées de cendres volcaniques grises jusqu’à 50 m de haut.
La JMA a déclaré “le phénomène a été très court et quelques cendres volcaniques ont été émises” mais ils ne précisent aucune donnée quantitative. Les cendres volcaniques émises n’ont pas officiellement été échantillonnées pour évaluer leur distance de parcours. Ils n’expliquent pas non plus pourquoi.
Aucun communiqué officiel sur cette éruption n’est publié sur la page d’accueil de leur site.
Ils affirment qu’il s’agit d’une éruption mais ils ne trouvent pas approprié de la qualifier ainsi pour ne pas paniquer les gens.

Il n’y a que 80 km entre le Mt. Hakone et le centre de Tokyo.

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.
