* 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.

The tsunami reached Rokuchonome-higashi on Prefectural Route 23 (4.5 km from the coast).  Water depths were measured along the road (about 1 m at 3 km from the coast).  However, we returned to the university after hearing reports of an increase in radiation at the Onagawa Nuclear Plant.
