The author conducted questionnaire survey on evacuation in the city and collected 324 cases. This study examined statistical data of human casualty and analyzed the questionnaire data to clarify affecting factors for evacuation. The findings are as follows. Considering day time population, fatality rate distribution vs age groups is estimated. As for travel means, automobiles share majority of 65% and traffic jam became severer due to delay.
