The 2025 MW7.0 Dingri Earthquake: Conjugate Normal Faulting of a Graben Structure in the Southern Xainza‐Dinggye Rift

Geophysical Research Letters, Volume 52, Issue 12, 28 June 2025.
Abstract The 2025 MW ${M}_{W}$7.0 Dingri earthquake, which struck southern Tibet on 7 January 2025, provides kinematic insights into extensional tectonics in the region. We use Sentinel‐1 and Lutan‐1 Synthetic Aperture Radar (SAR) data sets to analyze the coseismic displacement fields of this event.
