タイトル（英）：	DETAILED SOURCE PROCESS OF THE 1995 HYOGOKEN NANBU (KOBE) EARTHQUAKE USING NEAR-SOURCE STRONG GROUND MOTION DATA
抄録（英）：	We investigated the source process of the 1995 Hyogo-ken Nanbu earthquake by the waveform inversion assuming a fault branching at the northeastern part of the fault model. Possibility of the fault branching was suggested by the static displacements and comparison between the “damage belt” distribution and strong ground motion simulation. We found relatively large slips at the deep part of the branch. Total variance reduction is larger and waveform fitting is better when we assumed the branch than those when we did not. Resolution checks showed that our data set can discriminate the slip on branching two segments, and that the slips on the branch is caused neither by random noise contained in the data nor by synthetic errors of the Green's function due to mis-estimation of shallow velocity structures. We conclude that possibility of the branching could be high.
