The Xianshuihe fault is shown by red line with historic earthquakes M 7 and M 6 marked by green and black hollow stars, respectively. Red hollow stars represent the 2014 Kangding earthquake doublet. Heavy gray lines indicate the thrust faults at the tectonic junction, and the heavy dark lines show the strike‐slip faults. Other active faults are shown by light gray lines. Open black circles represent the relocated aftershocks (Zhang et al., 2023). Blue triangles indicate the high‐rate Global Navigation Satellite System (hrGNSS) sites. Magenta rectangles represent counties nearby. Green rectangle marks the Gonggashan Mountain. The GNSS secular velocities from Wang and Shen (2020) are depicted by cyan arrows.
