Tsunami Trace survey

The terrible tsunami attacked the Tohoku region. Fortunately,  the damage of Hokkaido was very limited. We were very lackey.

We started to survey the Hokkaido coastal line and rivers in Hokkaido.







I was in charge of between Oshamannbe and Hakodate.
There were several traces of the Tsunami in rivers and towns.

The trace of inundation in the downtown of Hakodate city was the biggest about 60cm depth.
