Detailed source rupture propagation for case B. a Snapshots of the source rupture propagation. The stars in the upper panels denote the first rupture initiation point (the hypocenter). The stars in the lower panels denote the second rupture initiation point on segment S3. The two rectangles show the large slip areas A1 and A2. b Velocity waveforms (0.05–0.4 Hz) in the east–west component at the three near-source stations. For each station, the first waveforms from the top show a comparison between the observation and the synthetic calculated for the entire fault. The second and third waveforms from the top show the synthetics calculated using only the large slip areas A1 and A2, respectively. The map view shows the location of the stations (triangles), the epicenter (star), and the large slip areas (rectangles)
