A professor emeritus Kasahara from Tokyo university points out the possibility that it might have been a volcanic earthquake.

He comments there was a continuous “earthquakes” in that location on 2/24/2013, which can’t be separated into individual quakes.

On 2/26/2013, 3.3 cm of diastrophism to North West was detected at the monitoring posts near the epicentral area.

By 14:00 of 2/26/2013, 54 of afteshocks over scale1 have been detected but Japan meteorological agency states they don’t think it was a volcanic earthquake.

M. Kasahara, professeur émérite de l’université de Tokyo fait remarquer que la possibilité que ce séisme soit d’origine volcanique.

Il précise qu’il y a eu un séisme continu à cet endroit le 24 février 2013, ce qui ne peut pas être découpé en séismes individualisés.

Le 26 février 2013, 3,3 cm de diastrophisme vers le Nord-Ouest a été détecté par les bornes de surveillance près de la région de l’épicentre.

Le 26 février 2013 vers 14:00, 54 répliques d’intensité supérieure à 1 ont été relevés mais la Japan Meteorological Agency affirme qu’ils ne pensent pas que ce soit un séisme volcanique.

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.
