東日本大震災後の大槌町における避難所へのアクセスに関する研究

－スモールインフラストラクチャーとしての山道－

抄録

By analyzing the situation of the villages in Otsuchi-Town soon after the earthquake, the following three conclusions are drawn. After the tsunami, those who escaped to the higher places were isolated, because roads had been occupied by the rubble. But some people got the access to the neighboring villages by using the mountain paths. After the construction of the seaside road, some mountain paths gradually began to be rarely used, then disappeared around 1970's. In order to take precautions against the next earthquake, the relationship between sea and mountains along the Sanriku caostal area should be improved.
