Spatiotemporal characteristics and multiple coupling mechanisms of pre-seismic ionospheric electromagnetic anomalies before the Madoi earthquake

Geomatics, Natural Hazards and Risk
Electromagnetic anomalies before earthquakes exhibit significant short-term characteristics. In this study, we first employed the non-negative matrix factorization (NMF) method to extract anomalies in the electric field, magnetic field, and electron ...

Resolving co- and early post-seismic slip variations of the 2021 MW 7.4 Madoi earthquake in east Bayan Har block with a block-wide distributed deformation mode from satellite synthetic aperture radar data [PDF]

Earth and Planetary Physics, 2022
On 21 May 2021 (UTC), an MW 7.4 earthquake jolted the east Bayan Har block in the Tibetan Plateau. The earthquake received widespread attention as it is the largest event in the Tibetan Plateau and its surroundings since the 2008 Wenchuan earthquake, and

Spatiotemporal Evolution Characteristics of Outgoing Longwave Radiation (OLR) Anomalies Before the 2021 Ms7.4 Madoi Earthquake

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Outgoing longwave radiation (OLR) anomalies before large earthquakes have been widely detected. In most of the current research, the identification of seismic-related anomalies predominantly relies on conventional thresholds (e.g., $k*\sigma $), which ...

The 2021 M_w 7.4 Madoi Earthquake: An Archetype Bilateral Slip‐Pulse Rupture Arrested at a Splay Fault [PDF]

Geophysical Research Letters, 2022
AbstractWe combine measurements of ground deformation from Synthetic Aperture Radar images, high‐rate Global Navigation Satellite System and tele‐seismic waveforms to study the rupture kinematics of the Madoi Earthquake, which occurred in eastern Tibet on 21 May 2021 and reached a moment magnitude Mw 7.4.

Dynamic Rupture Process of the 2023 Mw 7.8 Kahramanmaraş Earthquake (SE Türkiye): Variable Rupture Speed and Implications for Seismic Hazard

Geophysical Research Letters, Volume 50, Issue 15, 16 August 2023., 2023
Abstract We considered various non‐uniformities such as branch faults, rotation of stress field directions, and changes in tectonic environments to simulate the dynamic rupture process of the 6 February 2023 Mw 7.8 Kahramanmaraş earthquake in SE Türkiye.

How Do Earthquakes Stop? Insights From a Minimal Model of Frictional Rupture

Journal of Geophysical Research: Solid Earth, Volume 128, Issue 8, August 2023., 2023
Abstract The question “what arrests an earthquake rupture?” sits at the heart of any potential prediction of earthquake magnitude. Here, we use a one‐dimensional, thin‐elastic‐strip, minimal model, to illuminate the basic physical parameters that may control the arrest of large ruptures.

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 ...

Characterization of thermal infrared medium- and short-term anomaly information from block to fault in mainland China

Frontiers in Earth Science, 2023
The relationship between satellite thermal infrared anomalies and earthquakes or fault activity has been studied for more than 30 years. In this study, five strong earthquakes (the MS6.1 earthquake in Biru, Tibet; the MS7.4 earthquake in Madoi, Qinghai ...
