This study employs time-series InSAR technology to extract the interseismic surface deformation field along the Anninghe-Zemuhe fault zone on the eastern margin of the Sichuan-Yunnan rhombic block. We further invert the interseismic slip rates and locking depths of the fault system. Key findings include: the cross-fault InSAR deformation velocity gradient along the Anninghe fault increases progressively from ~2 mm/a in the northern segment to ~2.5 mm/a in the southern segment, whereas the Zemuhe fault exhibits a relatively smaller gradient of ~1.8 mm/a.Slip rates along the Anninghe fault vary spatially: ~2.8 mm/a at the northern Shimian segment, ~4.0 mm/a at the central Mianning segment, and ~3.2 mm/a at the southern Xichang segment. The Zemuhe fault shows a decreasing slip rate from ~3.1 mm/a in the northern segment to ~2.6 mm/a in the southern Ningnan segment.Locking depth analysis reveals maximum values (~37.8 km) beneath the Xichang segment, gradually shallowing northward to ~5.0 km at Shimian and southward to ~13.2 km at Ningnan.These results demonstrate that the Xichang segment, characterized by higher slip rates and deeper locking depths, exhibits enhanced seismic potential, consistent with its historically dense seismicity. This spatial correlation between geodetic deformation patterns and seismic activity provides critical insights into strain accumulation processes within this active tectonic boundary.
