Application of Singular Spectrum Analysis (SSA) for Delineating Geomagnetic and Lithospheric Signatures Associated With M7.6 Japan Earthquake

Earth and Space Science, Volume 13, Issue 3, March 2026.
Abstract In this paper, Singular Spectral Analysis (SSA) is applied to the geomagnetic field to delineate signatures from different sources, such as geomagnetic variability and lithospheric processes. We performed SSA on the Y component of the Swarm satellite magnetic field By during the period from September 2023 to January 2024. Eigen values obtained

Coseismic Deformation Obtained by Various Technical Methods and Its Constraint Ability to Slip Models of Maduo Earthquake

Remote Sensing
The coseismic deformation field on both sides of the fault, especially the distribution and change characteristics of near-field deformation, not only provides important constraints for the fine inversion of the slip distribution model but also serves as

Source model for the M w 6.0 earthquake in Jiashi, China on 19 January 2020 from Sentinel-1A InSAR data

Earth, Planets and Space, 2020
On January 19, 2020, an M w 6.0 earthquake occurred in Jiashi, Xinjiang Uygur Autonomous Region of China. The epicenter was located at the basin-mountain boundary between the southern Tian Shan and the Tarim Basin.

Horizontal coseismic deformation of the 1999 Chi-Chi earthquake measured from SPOT satellite images: Implications for the seismic cycle along the western foothills of central Taiwan [PDF]

, 2003
The 1999 Chi-Chi earthquake, M_w = 7.6, broke a major thrust fault along the western foothills of the Central Range of Taiwan. We have measured the horizontal coseismic displacement field by correlating optical satellite images acquired before and after ...

Coseismic Deformation From Earthquake Faulting On A Layered Spherical Earth [PDF]

Geophysical Journal International, 1996
SUMMARY A method for calculating the static displacement field following earthquake faulting in a layered spherical earth is presented. At shallow levels, the Earth’s layering is characterized by sharp jumps in bulk and shear moduli at the Conrad discontinuity and the Moho and is therefore important to consider when evaluating crustal deformation.

Fault Stability Assessment in Tectonically Active Geothermal Fields Through Integrated Stress Analysis

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 3, March 2026.
Abstract The Tulu Moye geothermal field in the actively deforming Main Ethiopian Rift presents substantial potential for renewable energy production, where interactions between fault systems, hydrothermal fluids, and tectonic activity require careful management for sustainable development. Here we present a first‐order assessment of fault stability and

Near-field propagation of tsunamis from megathrust earthquakes [PDF]

, 2007
We investigate controls on tsunami generation and propagation in the near-field of great megathrust earthquakes using a series of numerical simulations of subduction and tsunamigenesis on the Sumatran forearc. The Sunda megathrust here is advanced in its

Influence of the Loading Stiffness on Sheared Granular Fault Gouge, and Applicability to Slip‐Weakening Theory

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 3, March 2026.
Abstract Tectonic faults can slip in a spectrum of fault slip behaviors, from aseismic slip and slow ruptures to elasto‐dynamic earthquakes. Following frictional theory, laboratory experiments have shown that the basic ingredient that may control this transition is the interaction between the fault stiffness and the surrounding elastic medium.
