Outline of Final Research Achievements

The present research aims to analyze which types of evacuation triggers worked among coastal residents based on the published results of post field surveys conducted after recent tsunami events. First the actual evacuation triggers were classified into categories and then the main triggers in each area were identified. The results of this analysis show that the types of triggers that worked during these events depended on the levels of tsunami awareness in each area. These results clearly indicate that efforts to achieve and retain a high level of tsunami awareness are required in tsunami-prone coastal areas in order for residents to successfully evacuate.
