Abstract

Evacuation activity in early stage of the flood disaster is a matter of importance from the viewpoint of the mitigation of injury. The timing for the decision making in which the inhabitant starts the evacuation activity is based on the disaster consciousness of the inhabitant, and the disaster consciousness is formed by flood experience of the inhabitant himself legend on the flood damage in the past and social education, etc..

Main conclusions are as follows. First, the atrophy of disaster consciousness delay the evacuation activity.
