National institute “Mt. Fuji can erupt in next mega earthquake / same state as just before the last eruption in 1707”

According to the researching team of National Institute of Advanced Industrial Science and Technology (belongs to Ministry of Economy, Trade and Industry), Mt. Fuji can erupt in the next large earthquake.

They described Mt. Fuji as “a balloon ” full of magma and gas. The potential major earthquake can cause diastrophism so the stocked magma and gas may splash from the cracks of the dike inside of the mountain body.

They stated it’s in the same state as just before the last eruption called Houei great eruption in 1707.

In Houei great eruption, M8 level of an earthquake hit in 1703. 4 years later, M 8.6 ~ 8.7 level of another earthquake occurred and Mt. Fuji erupted 49 days later. The second earthquake had two epicenters in Tokai offshore and Kii offshore.

Rumbles in the ground was observed since 1 month after the earthquake, and M4~5 level of the earthquakes happened several times one day before the eruption.

It is recorded the eruption last for 2 weeks, Tokyo (Edo) had the sky covered with volcanic ash to cause the serious shortage of food and respiratory illness. It’s also recorded that Mt. Fuji was in the relatively stable state until the M8.6 ~ 8.7 earthquake. [Wikipedia]


National Institute of Advanced Industrial Science and Technology comments Mt. Fuji has been stocking magma for 300 years since Houei great eruption.

L’institut national  : “Le Mt. Fuji pourrait entrer en éruption au prochain grand séisme / Exactement comme juste avant la dernière éruption de 1707”


Selon l’équipe de recherche du National Institute of Advanced Industrial Science and Technology (qui dépend du ministère de l’Economie, du Travail et de l’Industrie), le Mt. Fuji peut entrer en éruption au prochain grand séisme.

Ils décrivent le Mt. Fuji comme “un ballon ” rempli de magma et de gaz. Le prochain grand séisme provoquera probablement un diastrophisme qui fera jaillir le magma et les gas par les fracture du dike contenu dans le corps de la montagne.
Ils affirment qu’il est dans le même état que celui qu’il avait juste avant sa dernière éruption nommée la grande éruption de Houei en 1707.
Lors de la grande éruption de Houei, un séisme de magnitude 8 avait frappé en 1703. 4 ans plus tard, un autre de M 8.6 ~ 8.7 a frappé aussi et le Mt. Fuji est entré en éruption 49 jours après. Le second séisme avait deux épicentres au large de Tokai et de Kii.
Des grondements dans le sol avaient été entendus à partir d’un mois après le séisme  et des séismes de M4~5 sont survenus la veille de l’éruption.
L’éruption a été enregistrée pendant 2 semaines, le ciel de Tokyo (Edo) était rempli de cendres volcaniques qui ont provoqué des pénuries de nourriture et des maladies respiratoires. Il est également écrit que le Mt. Fuji avait été dans un état relativement stable jusqu’au séisme M8.6 ~ 8.7. [Wikipedia-en] (ndt: en anglais, moins détaillé que la version japonaise donnée par Iori ci-dessus et il n’en existe pas de version française)

Le National Institute of Advanced Industrial Science and Technology déclare que le Mt. Fuji accumule du magma depuis 300 ans , depuis la grande éruption de Houei.

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.
