Constraining Shear Strength of Fault Damage Zone Using Geodetic Data and Numerical Simulation

Geophysical Research Letters
Shear strength of damage zone, representing the stress threshold for rupture initiation, is a critical parameter in faulting mechanics. Despite its significance, the damage‐zone's shear strength has not been estimated in natural earthquake ruptures. Here

Discontinuous Surface Ruptures and Slip Distributions in the Epicentral Region of the 2021 Mw7.4 Maduo Earthquake, China

Remote Sensing
Geometric complexities play an important role in the nucleation, propagation, and termination of strike-slip earthquake ruptures. The 2021 Mw7.4 Maduo earthquake rupture initiated at a large releasing stepover with a complex fault intersection.

Analysis of Damage Mechanism of Heihe Bridge during the Maduo Earthquake

Journal of Physics: Conference Series, 2023
Abstract It is of great significance to discuss the earthquake damage mechanism of the bridge. In this paper, the seismic damage mechanism of Heihe Bridge is analyzed based on the post earthquake data. Firstly, the seismic response of Heihe Bridge is analyzed based on the finite element software Midas/Civil, and the model of Heihe Bridge

Interaction between historical earthquakes and the 2021 Mw7.4 Maduo event and their impacts on the seismic gap areas along the East Kunlun fault

Earth, Planets and Space, 2022
On May 21, 2021 (UTC time), an Mw7.4 earthquake struck Maduo County, Qinghai Province, China. The rupture of this typical strike-slip event and its aftershocks along the Kunlun-Jiangcuo fault (JCF) propagated approximately 170 km from the epicenter.
