The evacuation environment from the tsunami was changed significantly along Sanriku coastal region because of reconstructions of land use, transportation infrastructure and tsunami evacuation facilities. The evacuation to the nearest evacuation place does not necessarily mean that you can escape the tsunami flooded area quickly. Rather than the evacuation to the nearest evacuation place, the evacuation to the outside of the tsunami flooded area by use of the shortest distance route is effective to evacuate from tsunami. In this study, we analyzed the applicability of the procedure of evacuation to the outside of tsunami flooded area at fast. Through the analysis of the tsunami evacuation route before the Great East Japan Earthquake and also after the completion of the reconstruction project, we clarified the applicability of the procedure of escaping from the tsunami flooded area and evacuate to the evacuation place.
