The aim of the present paper is to assess earthquake hazard to human life from major active fault systems distributed across the Japanese archipelago and propose the way of evaluating grade of risk which caused by each active fault system. Firstly, the authors estimate "potential disaster area" where a ground shaking(acceleration) of PGA≥400(cm/s^2) will endanger human life from anticipated earthquakes in each major active fault system. Secondly, "presumed damage population" are estimated from "potential disaster area" and population data. We fix grade of risk from "presumed damage population". Finally, we examine stability of obtained grade of risk and relation between "presumed damage population" and length of each active fault system to show efficacy of proposed grade.
