The shallow slip deficit (SSD) during strike-slip earthquakes raises a question of how the strain budget is accommodated over multiple cycles. However, the origin of variable SSD observed in different earthquakes is still under debate because each ...

Geometric and kinematic analysis of faults bordering the Andaman sea continental shelves: a 3D seismic case study [PDF]
To clarify the tectonic evolution of M15 block in the Andaman Sea, we perform a delicate study of fault geometry and dynamics using a 3D seismic data. The data reveal eight sequence interfaces from the Early Oligocene to the Quaternary, large scale and ...

Abstract We present high‐resolution rupture imaging of the 2025 MW 7.7 Myanmar earthquake using global teleseismic P‐waves and regional‐distance Rayleigh waves. Most radiated energy was released near the epicenter within the first 20 s, followed by bilateral rupture propagation along the central Sagaing Fault, extending ∼350 km southward and ∼100 km ...

Abstract The amount and spatial distribution of surface displacement that occurs during an earthquake are critical information to the understanding of the earthquake source and rupture processes. However, the earthquake surface displacement occurs over wide regions, includes multiple components that affect the ground surface at different spatial scales,

Slip Deficit Rate and Seismic Potential on Crustal Faults in Tibet
Abstract Quantifying slip deficit rates on active faults in Tibet is essential for understanding fault kinematics and assessing seismic hazards, but has not been fully characterized, particularly on secondary faults. In this study, we integrate an updated interseismic Global Navigation Satellite Systems velocity field from 4,458 stations across ...

Coarse-graining research of the thermal infrared anomalies before earthquakes in the Sichuan area on Google Earth engine [PDF]
Seismo-induced Thermal infrared (TIR) anomalies has been proposed as a significant precursor of earthquakes. Several methods have been proposed to detect Thermal infrared anomalies that may be associated with earthquakes.

Supershear Rupture During the 2021 MW 7.4 Maduo, China, Earthquake
AbstractCombined with the multi‐array back‐projection and finite‐fault joint inversion methods, we investigate the detailed spatiotemporal rupture complexity of the 2021 MW 7.4 Maduo earthquake using seismic and geodetic data. Our results reveal that this earthquake ruptured bilaterally 170 km long fault segments with a duration of 38 s.

Coseismic Shallow Slip Deficit Accounted for by Diffuse Off‐Fault Deformation
Abstract Earthquake ruptures produce fault slip and kilometer‐wide diffuse deformation of the host rocks. However, the origin of the diffuse deformation and its role in the rupture process are debated. We produce a refined slip model for the 2019 Ridgecrest, California, earthquakes, and analyze the relations between down‐dip rupture process, and ...

Abstract The 2021 Mw 7.4 Maduo earthquake within the Bayan Har block allows us to understand the lithospheric mechanical properties in northeastern Tibet. We analyze possible postseismic processes by modeling the six-month postseismic deformation from Interferometric Synthetic Aperture Radar data.

针对2011年提出的两步差法在地震微波异常提取中的不足,提出了改进两步差法,该方法通过使用层次聚类和小波分析两种算法,克服了原方法中未考虑不同地物类型引起的亮温差异、亮温背景场不够稳健等问题,从而使异常结果在空间形态和异常幅度上更加合理,并将该方法应用于2021年5月22日青海省玛多县MS7.4地震的微波异常提取。结果显示,玛多地震前三个月出现了一条长约900 km、增温幅值达12 K的NE向亮温增温条带,与2010年4月14日MS7.1玉树地震前异常特征在空间分布和演化特征上均有很高的相似性。此外 ...
