Fig. 2: On-fault displacement observations of the earthquake doublet.

a Orthorectified pre- and post-event GF-7 images and post-event Google Earth image (Map data ©2024 Google). b On-fault slip measurements from linear and displaced surface markers in the pre- and post-event images. White lines are used as a reference. c, d Along-strike distribution of on-fault slip related to the 7.8 ruptures. e, f Along-strike distribution of on-fault slip related to the 7.6 ruptures. Colored circles represent slips that we determined; the others were reported in previous investigations27,28,29.
