[1]. Table I and Table II show the
questionnaire results. In Table I, they asked the behaviors when
people knew evacuation instructions or evacuation directives.
The answer “Remained in their houses” was the first place. In
Table II, top reasons for this were “They thought evacuation
was dangerous because of heavy rain during the night” and
“They did not think that they suffer from the disaster”. Thus, it
is obvious that the current information delivery method is not
suitable to residents. In particular, the current evacuation
advices and instructions do not inform risk enough, because the
scope of these advices and instructions are too wide.
