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

Simultaneous rupture propagation through fault bifurcation of the 2021 Mw7.4 Maduo earthquake

Geophysical Research Letters, 2022
AbstractFault 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 understanding of rupture dynamics and seismic hazard.

Stress Evolution Before and After the 2021 Mw 7.3 Maduo Earthquake in Northeastern Tibet and Its Influence on Seismic Hazards

Earth and Space Science, 2022
The 2021 Mw 7.3 Maduo earthquake ruptured the Kunlun Pass‐Jiangcuo fault (KPJF) in the Bayan Har Block (BHB) in northeastern Tibet. To explore the reasons behind the Maduo earthquake and the seismic hazards that followed this event in the BHB, we ...

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

Coseismic and early postseismic deformation due to the 2021 M7.4 Maduo (China) earthquake

Geophysical Research Letters, 2021
AbstractThe 2021 Maduo earthquake ruptured a 150 km‐long left‐lateral fault in the northeast Tibet. We used Synthetic Aperture Radar data collected by the Sentinel‐1A/B satellites within days of the earthquake to derive a finite fault model and investigate the details of slip distribution with depth.
