We propose an improved fault model of the Hyogo-ken Nanbu Earthquake for which an asperity is placed on the branch fault (branch fault model). The branch fault model is based on the result of source inversion which suggests that the rupture of the fault propagated also to the branch fault on the way. The result of the ground motion simulation by using the branch fault model agree better with observed motions than the results by using the previous fault model, for the sites located east of the fault for which the branch fault contributes much.
