Diastrophism is ongoing under Lake Biwa, from the research of prof. Kumagai of Ritsumeikan university.
5 years ago Kumagai’s researching group found out the sediment is blown up with bubbles from the lake bottom.
From the follow-up investigation implemented this October, approximately 10 sources of bubble were confirmed about 20m below the surface of the lake.
This place is assumed to have been the slope of a mountain over 400,000 years ago.
Lake Biwa is known to be shrunk from the eastern end and western end. The researching group states the old mountain ground is being pressured from the both sides of east and west to blow out the bubbles.
Selon les recherches du Pr. Kumagai de l’université de Ritsumeikan, un diastrophisme (déformation de la croute terrestre) est en cours sous le lac Biwa.
Il y a 5 ans, le groupe de recherche de Kumagai avait découvert que les sédiments du lac étaient soulevés par des bulles au fond du lac.
Les recherches suivantes, effectuées en octobre dernier, environ 10 sources de bulles ont été confirmée à environ 20 m sous la surface du lac.
Cet endroit est supposé avoir constitué la pente d’une montagne il y a plus de 400 000 ans.
Le lac Biwa est célèbre pour être rétréci à son extrémité Est et à son extrémité Ouest. Le groupe de recherche affirme que le sol de l’ancienne montagne est écrasé par les deux côtés, Est et Ouest, ce qui provoque les bulles.
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.
