Figure S10. A demonstration of how magnitude threshold affects stress drop spatiotemporal changes. (a) difference between pre-Sep 2004 and Sep 2004-Sep 2005, with different magnitude thresholds, (b) Difference between Sep 2004-Sep 2005 and post-Sep 2005, and (c) the detailed temporal change within the 1966 M6 slip patch marked with black dashed lines for different magnitude thresholds. All the items in this figure share the same meanings as those in Figure 10. Black squares point out the threshold used for final results. In each panel above, only the first subplot has NW and SE marks indicating the direction of the section on the SAF, and all the other subplots follow the same direction.
