Revetment of No.2 Sea Fort of today Taken on 19th Sept. Reiwa 1 (2019)

Due to large-scale earthquakes such as the Tokyo Metropolitan Earthquake and the Tokai-Tonankai-Nankai Earthquake, it was predicted that the ground would be liquefied and the revetment would collapse, causing sediment to flow out into the channel. As “preventive maintenance”, we are working on improvement of the revetment of the No.2 Sea Fort.

Sediment flows into the water way due to an earthquake.
