Abstract
The paper proposes a model to describe the technical effectiveness of rescue activities in case of large-scale earthquakes in order to suggest the efficient equipment for quicker response. The model employs two factors which represent the speed of searching victims captured in the destroyed structures and the accuracy of detecting them. The model was applied to the data of relieved victims of the Hanshin Great Earthquake. And provided a reasonable reproduction of the data. Parametric studies concerning to the two factors suggested that increasing the accuracy of detection may be more effective than increasing the speed of search if the two are as given for the Hanshin earthquake.
