Complex strike-slip faulting during the 2021 Mw7.4 Maduo earthquake

, 2023
Fault geometry is an essential component for understanding earthquake genesis and dynamic rupture propagation. Here we employed space-based geodetic observations and geological survey, adopting a fully Bayesian approach, to probabilistically estimate the

Along-dipping variations in fault geometry influencing shallow-slip-deficit during the 2021 MW7.4 Maduo earthquake

Geodesy and Geodynamics
The shallow slip deficit (SSD) during strike-slip earthquakes raises a question of how the strain budget is accommodated over multiple cycles. However, the origin of variable SSD observed in different earthquakes is still under debate because each ...

Study on deformation and structural characteristics of the M w 7.4 earthquake fault zone in Maduo, Qinghai Province by combining optical, InSAR and seismic data

, 2023
Abstract By means of D-InSAR and weighted least square method, the coseismic deformation field of the Mw7.4 earthquake in Maduo, Qinghai Province on May 22, 2021 was solved by using Sentinel-1A data of ESA. The horizontal deformation field of earthquake was extracted from Sentinel-2 optical data, and the vorticity field, divergence field, and ...

Fault Orientation Trumps Fault Maturity in Controlling Coseismic Rupture Characteristics of the 2021 Maduo Earthquake

AGU Advances, Volume 5, Issue 2, April 2024.
Abstract Fault maturity has been proposed to exert a first order control on earthquake rupture, yet direct observations linking individual rupture to long‐term fault growth are rare. The 2021 Mw 7.4 Maduo earthquake ruptured the east‐growing end of the slow‐moving (∼1 mm/yr) Jiangcuo fault in north Tibet, providing an opportunity to examine the ...
