Tsunami evacuation plannings have been built on "alert-evacuation" model, which assumes "tsunami alert -transmission -evacuation behavior" connection. Analyzing the data on the behavior of residents (n=1,710) in coastal area of Aichi prefecture after the tsunami warning on September 5, 2004, the results indicated that only a few residents evacuated despite their strong concerns on tsunami. This behavioral pattern results from the "empirical knowledge" which was gained by their past experience of not evacuating after a tsunami alert. In order to transform this knowledge, we need to build a new evacuation model based on the understandings of ambiguity which people face in disasters.
