Providing 2022 Menyuan seismic fault models derived from geodetic observations and seismic parameter inversion
Two earthquakes struck Menyuan, Qinghai province in Northwest China: Mw 5.9 event on 26 January 2016 and Mw 6.7 event on 8 January 2022. The interferometric synthetic radar (InSAR) technique was utilized to retrieve high resolution co-seismic surface displacement maps for both events.
The co-seismic surface displacements were then inverted to determine the fault geometry parameters and the non-uniform fault slip distributions with a dislocation model in an elastic half-space.
Our results are shared here, including distributed fault sliding models for the 2016 Menyuan Earthquake and the 2022 Menyuan Earthquake.
The data format is “lon(deg) lat(deg) str(deg) dip(deg) dep(km) wid(km) leng(km) s_slip(m) d_slip(m) o_slip(m)”
