タイトル(英): SOURCE MODEL OF THE 1997 KAGOSHIMA-KEN HOKUSEIBU EARTHQUAKE FOR THE INTERMEDIATE PERIOD RANGE
抄録(英): To evaluate source model of the March,1997 Kagoshima-ken Hokuseibu earthquake for the intermediate period range around 1s, we estimate underground structure models separately for five stations based on the forward waveform modeling of aftershock records in that period range. Asperity area is extracted from the slip model with following the criterion by Somerville et al.(1999). The asperity area obtained by this study is consistent with that by long-period (>2s) waveform inversion (Miyakoshi et al., 2000).
