Recently, structural damage caused by the middle-scale earthquake were reported. These damage were not so serious, but middle-scale earthquake is often generated. It is important that study of the source modeling the middle-scale earthquake. In this study, we attempted to make a source model of middle-scale earthquake by the empirical Green’s function method. The target earthquake is inland crustal earthquake with Mj5.6 which occurred in southern Nagano prefecture in Japan on 25th June 2017. Resultantly, we proposed source model with single strong motion generation areas located in near hypocenter.
