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

Communications Earth & Environment, 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

Simultaneous Rupture Propagation Through Fault Bifurcation of the 2021 Mw7.4 Maduo Earthquake

Geophysical Research Letters, 2022
Fault geometric complexity plays a critical role in earthquake rupture dimension. Fault bifurcations are commonly observed in earthquake geology, yet, robust kinematic rupture processes on bifurcated fault branches are largely missing, limiting our ...

Geodetic Constraints on Fault Kinematics and Dynamics of 2021 Maduo Earthquake: Implications for Fault Friction [PDF]

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 7, July 2026.
Postseismic afterslip has been inferred to occur on fault barriers surrounding coseismic asperities, which can be explained by velocity-strengthening friction in barriers and velocity-weakening friction in asperities.

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

AGU Advances, Volume 5, Issue 2, April 2024.
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.

Non‐Typical Supershear Rupture: Fault Heterogeneity and Segmentation Govern Unilateral Supershear and Cascading Multi‐Fault Rupture in the 2021 Mw ${M}_{w}$7.4 Maduo Earthquake

Geophysical Research Letters
Previous geodetic and teleseismic observations of the 2021 Mw7.4 Maduo earthquake imply surprising but difficult‐to‐constrain complexity, including rupture across multiple fault segments and supershear rupture.

Coseismic Deformation Obtained by Various Technical Methods and Its Constraint Ability to Slip Models of Maduo Earthquake

Remote Sensing
The coseismic deformation field on both sides of the fault, especially the distribution and change characteristics of near-field deformation, not only provides important constraints for the fine inversion of the slip distribution model but also serves as

Piezomagnetic Anomalies Associated with the 2021 M_W 7.3 Maduo (China) Earthquake [PDF]

Applied Sciences, 2022
Stress changes due to earthquake rupture can disturb geomagnetic fields significantly. In order to investigate the impact of the 2021 MW 7.3 Maduo earthquake on geomagnetic fields, a piezomagnetic model is constructed based on the coseismic slip to ...

High-Probability Ground Motion Simulation in Maduo County for the Maduo MS7.4 Earthquake in 2021:A Possible Supershear Earthquake

Journal of Earth Science
On May 22, 2021, an MS7.4 earthquake occurred in Maduo County, Qinghai Province, on the western plateau of China. The level of seismic monitoring in this area was inadequate, and incomplete seismic waveforms were obtained from a few broadband ...
