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.

• 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.
