Abstract

This study examines elementary school students’ perceptions of a tsunami risk after an earthquake occurrence. Following the earthquake that occurred on February 6, 2015 in the southern region of Tokushima Prefecture, Japan, some elementary schools experienced relatively strong ground motions. A questionnaire survey was administered to the students of an elementary school in this area. This school is located in an estimated tsunami inundation area of the Nankai Trough earthquake. The results showed that many students experienced anxiety after the earthquake. It was revealed that these states arose from the students’ perceptions of the ground motions and tsunami hazard. The perception of the possible tsunami attack was strongly associated with that of evacuation necessity. In contrast, students who perceived that ground motions were strong did not tend to recognize the possible tsunami attack and evacuation necessity. These results indicate that, even if students have learned disaster risk reduction activities before massive earthquake, strong ground motions may disturb their perceptions of evacuation necessity. Therefore, the consideration of students’ anxiety states after earthquake is crucial in the emergency response management and tsunami warning system.
