Two volcanos are also becoming active in surrounding area of Tokyo.

(cf, Mt. Hakone keeps expanding / Land rose up by 4 cm again in the north of crater from 5 days ago [URL])

(cf, Very shallow volcanic quake occurred the most often since 311 in Mt. Asamasan [URL 2])

Japan Meteorological Agency has not mentioned the potential relationship with those volcanic activities and recurring quakes.

La Japan Meteorological Agency rapporte que le 25 mai 2015 à 14:28 (JST), un séisme M5,6 a frappé le nord de Tokyo.

Son épicentre était au nord de la préfecture de Saitama. Cependant, le maximum de son intensité sismique (5-) a été relevé dans la préfecture d’Ibaraki.
Le 22 mai 2015, un M5.1 avait frappé l’île d’Amami-oshima avec une intensité sismique maximale de 5- également.
Deux volcans sont en train de devenir actifs dans la région entourant Tokyo.
(cf. Le Mt. Hakone continue de gonfler : Le sol est encore monté de 4 cm en 5 jours au nord du cratère)
(cf. Le nombre de séismes superficiels du Mt. Asama est au plus haut depuis le 11-3)

La Japan Meteorological Agency ne fait mention de lien possible entre ces réveils de volcans et ces séismes récurrents.

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.
