In the Great East Japan Earthquake, a large number of residents lost their lives because they were unable to take appropriate evacuation actions despite the fact that there was spare time before the arrival of the tsunami and despite the fact that calls for evacuation had been issued by local governments and broadcasting stations.
In order to overcome this problem, since the Great East Japan Earthquake, broadcasters have been taking measures to improve their "methods of calling for evacuation" (caster comments, announcement methods, screen display design, etc.), but there has been little empirical analysis of how they have been received by the public.
In this study, we conducted a qualitative survey (depth interviews) of people who experienced tsunami evacuation during the Great East Japan Earthquake in order to find out how people evaluate the new caster comments and announcement methods.
As a result, it was found that there were a variety of perceptions depending on local conditions and individual experiences, but there was a certain trend in the evaluation of suitability.
Based on these results, it was suggested that open discussion of the evacuation call itself with the audience may lead to increased sensitivity to information and enhanced effectiveness of the call.
