The object of this paper is to propose a stochastic method for evaluating the magnitude of future earthquakes taking account of the nonstationariness in earthquake occurrence. For this purpose, the strain energy accumulation in a focal region was estimated by means of earthquake data of the past 100 years in Japan. Furthermore, distributions of maximum ground acceleration were derived by means of the attenuation law. As a result, we found that the distibutions of maximum ground acceleration fit type III extreme value distributions and that the expected values of those distributions depend on the strain energy accumulation significantly. Finally, it is pointed out that the nonstationariness in earthquake occurrence should be taken into consideration in order to evaluate the earthquake load in design. キーワード（英）： - 記事区分： - 区分 　　　　論文集
