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.

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

Earthquakes Have Accelerated the Carbon Dioxide Emission Rate of Soils on the Qinghai-Tibet Plateau. [PDF]

Glob Chang Biol
Earthquakes on the Qinghai‐Tibet Plateau not only damage infrastructure but also increase carbon dioxide emissions. This study found that fissures caused by these earthquakes expose frozen soils to the air, leading to an increase in soil carbon emission rates by 0.71 g CO2 m−2·a−1.

Source Model and Triggered Aseismic Faulting of the 2021 Mw 7.3 Maduo Earthquake Revealed by the UAV-Lidar/Photogrammetry, InSAR, and Field Investigation

Remote Sensing, 2022
Multi-source datasets, including the UAV-Lidar/Photogrammetry, InSAR, and field investigation data, have been used for revealing the complex surface displacement pattern and focal mechanism of the 2021 Maduo Mw 7.3 earthquake. First, a co-seismic surface
