越えるようなことはなく，船も人もまったく無事とのことです．
岸壁の高さは測りました．
* Hokkaido [#p848e76f]
2011/03/11: Here is a damage survey for the southern coast of Hokkaido Island along the Sea of Japan (ports of Yoichi, Iwanai, Setana, and Esashi). A Tsunami Alert* was temporarily announced in these regions after the main earthquake. Water level rises were observed in these ports early in the evening, but the tsunami did not surge over the quays. There were no victims, nor any damage reported to vessels. The heights of the quays are known.

Similar situation with gas stations, but fuel is scarce. Conducting damage surveys are very difficult. National Route 4 is congested but passable. However, the access from National Route 4 to coastal areas is very poor.

2011/03/12 (reported by Dr. Koshimura, Tohoku University):
- The area between the southern bank of the Natori River and the northern part of Sendai Airport was surveyed. This area is a flat plain, and the tsunami invaded it through an underpass of the Sendai-Tobu Road. The tsunami reached 3 to 4 km inland. The plain was still flooded by muddy water, with the depth being about 1 meter at approximately 3 km from the coast (the only measurement made in this survey). Approaching the coast through this water is impossible.

However, we returned to the university after hearing reports of an increase in radiation at the Onagawa Nuclear Plant.

- 研究室・自宅はひどい状況．当分は片付けに追われる．
- ガソリンなどの物資が極端に不足している．緊急車両優先で給油は困難．
