Abstract
<p> In the 2011 off the Pacific Coast of Tohoku Earthquake Tsunami, embankments proved effectiveness in increasing evacuation time. On the other hand, a couple of researches pointed out that the residents' trust on embankments and sense of safety might influence the decision making of evacuation from the tsunami. The occurrence probability of the Nankai Trough earthquake within 30 years is expected to be 80%, disaster prevention measures against earthquakes and tsunamis are an urgent issue. This study conducted questionnaire survey in coastal area of Hamanatsu concerning on residents' awareness of tsunami disaster and tsunami embankment under construction. The covariance structure analysis of evacuation decision was conducted that took into account the recognision to embankment. The results show that although decreasing the risk perception of tsunami increases residents' trust on embankment and feeling of well protected, the perception of embankment has less direct impact on the evacuation decision making.</p>
