The Effect of Hydraulic Fracturing on the 2021 Ms 6.0 Luxian Earthquake as Revealed by Deformation and Numerical Simulations

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract This study investigates whether hydraulic fracturing contributed to the 2021 Ms 6.0 Luxian earthquake in the Sichuan Basin. Time‐series InSAR analysis of multi‐temporal Sentinel‐1 data reveals coseismic deformation associated with the 2021 Luxian earthquake and localized uplift near hydraulic fracturing platforms.
