This electronic supplement contains a table of the source parameters for the mainshock and selected aftershocks and figures of the fitness of the seismograms for selected aftershocks. Table S1 lists the source parameters of the mainshock and the chosen aftershocks studied in this work: locations, focal mechanisms, centroid depths, and moment magnitudes of the earthquakes are listed. Figures S1, S2, and S3, respectively, show the fitness between the observed data and the synthetic seismograms of aftershocks 3, 6, and 9, listed in Table S1.
Table S1. Source parameters of the mainshock and selected aftershocks studied in this work. Source locations are taken from Wang et al. (2014).
Figure S1. (a) The cut-and-paste (CAP) inversion result for aftershock 3 (see Table S1 for source parameters). The waveform fits for the best depth (7 km) are shown. The station names are indicated at the beginning of the record, along with distance in kilometers (top number) and azimuth in degrees (bottom number). The first number below each waveform pair is the time shift needed to align synthetic and observed data, and the second number is the waveform cross-correlation coefficient in percentage. A positive time shift indicates the velocity model is too fast. The focal mechanism at the top left corner shows the lower hemisphere projection of the mechanism (97°/90°/160°/4.09 for strike/dip/rake/Mw), and the open circles indicate station projections on the lower hemisphere, each according to its first-arrival P-wave take-off angle. (b) Depth resolution of the inversion.
Figure S2. The same as Figure S1, but for aftershock 6.
Figure S3. The same as Figure S1, but for aftershock 9.
