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.

Strain Threshold for the Formation of Coseismic Surface Rupture

Geophysical Research Letters, Volume 50, Issue 16, 28 August 2023., 2023
Abstract The 2021 Mw 7.4 Maduo earthquake (eastern Tibetan Plateau), with a surface deformation zone that is characterized by multiple distinct surface rupture segments separated by segments with no surface ruptures, provides an excellent opportunity to constrain the strain threshold (minimum strain) for the formation of surface ruptures.

Earthquake Cycle Deformation Associated With the 2021 MW 7.4 Maduo (Eastern Tibet) Earthquake: An Intrablock Rupture Event on a Slow‐Slipping Fault From Sentinel‐1 InSAR and Teleseismic Data

Journal of Geophysical Research: Solid Earth, Volume 127, Issue 11, November 2022., 2022
Abstract In the continents, the importance of earthquakes that occur away from major block‐bounding faults is still debated. The 21 May 2021 MW ∼ 7.4 Maduo earthquake occurred on a secondary fault away from previously‐identified major block boundaries.

A Shallow and Left‐Lateral Rupture Event of the 2021 Mw 5.3 Baicheng Earthquake: Implications for the Diffuse Deformation of Southern Tianshan

Earth and Space Science, Volume 9, Issue 3, March 2022., 2022
Abstract On 24 March 2021, an Mw 5.3 earthquake struck northwest Baicheng, located in the Kuqa fold‐and‐thrust belt (FTB), northwest China. In the current study, interferometric synthetic aperture radar (InSAR) data were used to investigate the associated fault rupture solution (dip, dip direction, and slip sense), to determine the geometry of the ...

Stress Transfer at the Northeastern End of the Bayan Har Block and Its Implications for Seismic Hazards: Insights From Numerical Simulations

Earth and Space Science, Volume 8, Issue 12, December 2021., 2021
Abstract The 2021 Mw 7.4 Maduo earthquake in Qinghai, China, filled the seismic gap in the eastern segment of the northern boundary of the Bayan Har Block, and four other M > 7 historical strong earthquakes occurred at the northeastern end of the Bayan Har Block within a period of 80 years before the Maduo earthquake.

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, Volume 51, Issue 20, 28 October 2024.
Abstract Previous geodetic and teleseismic observations of the 2021 Mw ${M}_{\mathrm{w}}$7.4 Maduo earthquake imply surprising but difficult‐to‐constrain complexity, including rupture across multiple fault segments and supershear rupture. Here, we present an integrated analysis of multi‐fault 3D dynamic rupture models, high‐resolution optical ...

Strain Partitioning in the Southeastern Tibetan Plateau From Kinematic Modeling of High‐Resolution Sentinel‐1 InSAR and GNSS

Geophysical Research Letters, Volume 51, Issue 19, 16 October 2024.
Abstract Fault slip rates estimated from geodetic data are being integrated into seismic hazard models. The standard approach requires modeling velocities and relative (micro‐)plate motions, which is challenging for fault‐based models. We present a new approach to directly invert strain rates to solve for slip rates and distributed strain ...

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

Geophysical Research Letters, Volume 51, Issue 10, 28 May 2024.
Abstract 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.
