Crustal change is heating the bottom of Biwa lake.

Sediment is blasted actively on the bottom of Biwako, the largest lake in Japan.
Mr. Kumagai ,the chairman of Lake Biwa environmental research institute talks, the environment of the late bottom is rapidly changing.

Since 2000, they have been investigating the bottom of the lake, 80~100 m deep by using submarine robot with video camera.
They have been checking the ground for longer than 10km from South to North.
In December of 2007,there were no sediment blasting observed but in December of 2009, they found 2 points every 1km. It increased to 9 points in December of 2010.
In January of 2012, it decreased to 7 points but the size of the blasting area increased from 1~2 m to 2~5 m.

Since 2008, the temperature of the water at 1.5m deep have became hotter than 1.0m. The bottom of the lake is heated.
Mr. Tsukuda Tameshige, the former assistant professor of Tokyo University earthquake research institute talks, the crustal change raised the pressure of underground, water underground or gas may be coming up from the cracks of the ground. The crust is highly distorted from Niigata to Kobe. Biwako is in the area.




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.
