The bottom of the sea rising up in Hokkaido / Land showed up overnight

In Shiretoko peninsula of Hokkaido, the bottom of the sea has been rising since 4/24/2015.

It’s the coastal line of Rausu town.

According to a local resident, she noticed the coastal line is slightly higher than usual when she was picking seaweed in the morning of 4/24/2015.

It already became higher than her when she came back home.

It kept on rising and it became 300 〜 500m wide, 30m long and 10 〜 15m high by the morning of 4/25/2015.

It is seen still rising.

Land subsidence is seen in the surroundings but no sound or quake were observed. Because the rising land has marine organisms attached, it is assumed not to be a landslide.

Sapporo Regional Headquarters of Japan Meteorological Agency commented there has not been earthquakes observed in this week. No significant volcanic activities are not seen either. The cause of rising sea bottom is not known.

Les fonds marins remontent dans Hokkaido : la terre s’est soulevée en une nuit


Dans la péninsule de Shiretoko le bord de mer se soulève depuis le 24 avril 2015.

Ça se passe sur la frange côtière de la commune de Rausu.
Alors qu’elle ramassait des algues au matin du 24 avril, une habitante a remarqué que le rivage était plus haut que d’habitude. Quand elle est rentrée chez elle, c’était monté sur plus que sa taille.

La subsidence a continué et au matin du 25 avril 2015 elle était visible sur une surface de 300 à 500 m par 30 m pour une montée de 10 à 15 m de haut.

C’est toujours en train de se soulever.

C’est visible des alentours. Le phénomène reste silencieux et sans séisme. On ne pense pas que ce soit un glissement de terrain puisque les organismes marins sont restés sur la zone en subsidence.

Le centre régional de Sapporo de la Japan Meteorological Agency a déclaré ne pas avoir observé de séisme cette semaine. Aucune activité volcanique n’a été remarquée non plus.
La raison de ce soulèvement de terrain reste inconnue.

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.
