Abstract

After the Great East Japan Earthquake, importance of evacuation from tsunami is increasingly acknowledged. The authors conducted two types of questionnaire surveys of residents' evacuation in Onjuku, Chiba focusing on an estimated tsunami in 2008, and on the event in 2011. Then acquired evacuation spatial data are compared in terms of altitude, distance from the coastal line, and the number of people in the inundated area. As a result, the actual evacuation activities in comparison with the estimated showed (1) diversity, (2) numerous uses of cars, (3) longer distance, and (4) more people in the inundation area.
