Rupture Process of the 2022 Mw6.6 Menyuan, China, Earthquake from Joint Inversion of Accelerogram Data and InSAR Measurements

We obtained the rupture process and slip distribution of 2022 Mw6.6 Menyuan earthquake by jointly inverting accelerogram data InSAR measurements. The near-field measurements provide good constraints on shallow distributions (<6 km). enable us to better resolve deeper coseismic (>6 combination two types provided improved constrains earthquake. results from joint inversion reveal a 26-km-long length, which roughly agrees with mapped length optically identified surface trace deformation field. imaged major asperity dimension 14 × 6 km at 4 depth updip hypocenter. maximum is estimated be 3.8 m depth. duration ~14 s, 90% seismic moment released in first 10 s. total 1.31 1 1019 N·m, equivalent magnitude Mw6.7. Our highlight that moderate but during could intensify damage surface, confirmed field investigations.
