The simulator of disaster range prediction by the diffusion of the noxious gas has been promoted in the various fields as the system combined with air flow diffusion analysis. However, in order to apply them right after the accident-generation, the time is required for decision of the input condition (type, quantity, positi.on of the emission quality, etc) and for calculation of the gas flow field, etc., and it is difficult to predict the extension of the disaster range immediately after the generation. In this paper, the method for quickly estimating disaster range extension from uncertain ano fragmental field information (only the initial range of the victim) gathered within a few minutes after the generation is shown.
