Abstract
After the 2011 Tohoku Earthquake tsunami, the disaster mitigation guarding human-life as the first object has become the most important issue. In this paper we carried out tsunami evacuation simulations for the Kesennuma city under two tsunami levels, by changing the evacuate operating method and the time of starting to evacuate. Through the simulations, it was recognized the difficulty of evacuation on elderly people safety, if they start to evaculate within 30min. As increasing cars more than 1000, the successful evacuation ratio becomes less than 40%, which is more danger than by walking evacuation due to the inceasing car traffic jams.
