IN SEPTEMBER 1990, THE TYPHOON 19TH LARGELY CAUSED PEOPLE TO INCURE A GREAT LOSS OF LIFE AND PROPERTY IN WESTERN JAPAN. THE AIM OF THIS PAPER IS TO GIVE AN OUTLINE OF THE ACTUAL CONDITION OF A FLOOD DISASTER. IN THIS STUDY, WE CLASSIFY RESIDENTS' BEHAVIOR INTO THREE CATEGORIES, 1) A SAFEGUARD BEHAVIOR AGAINST A DISASTER, 2) AN EVACUATION BEHAVIOR TO SHELTERS, 3) A BEHAVIOR FOR KEEPING THEIR DAIRY LIFE. WE CLEAR MAIN FACTORS THAT PROMOTE OR BLOCK EACH BEHAVIOR. WE WILL HAVE A CLEAR GRASP OF ACTUAL SITUATIONS OF VICTIMS' LIVING IN SHELTERS AND FIND THE CONDITIONS THAT SHELTERS SHOULD HAVE.
