Kikuchi method is applied for teleseismic body-waveform modeling
154 teleseismic body- waveforms (only P) is used. Magnitude 6.4 Strike/dip/rake: 168/53/130 The fault is dipping W-SW 2 main peaks in the source- time-function (STF), about 7 and 13 seconds after the rupture initiation. Total STF about 16 seconds. Kikuchi method is applied for teleseismic body-waveform modeling
Max slip about 90 cm. 2 different fault segments moved during the earthquake. That is why the GCMT solution shows substantial non-double-couple (NDC) component; better to say CLVD component. Segment 1 (between -6 and 10km along strike) was almost pure reverse. The slip contours of the first segment was deeper compared to that of segment 2. This is equivalent to the first peak (at 7 seconds) in the STF. Segment 2 (between 10km and 30km along strike) was behind the main energy release. It was a shallow reverse subevent with substantial strike-slip component.
Slip contours of 0.1 m The slip-distribution is very dependent on the epicenter location. It can be shifted based on the correct epicenter location.
Slip contours of 0.2 m.
Slip contours of 0.1 m with aftershocks recorded by IGTU.
