Deformation Features of Coseismic Surface Rupture

, 2017
The term coseismic surface rupture is defined as a surface fracture produced by a current or large historic earthquake. The term is interchangeable with surface earthquake fault and earthquake fault in Japan, which is enhanced for the topographic morphology and geometry of surface fractures formed during large earthquakes [Research Group for Active ...

Newly Discovered Active Faults in the Wairarapa Valley: Implications for Multi‐Fault Rupture and Kinematics in the Southern North Island, Aotearoa New Zealand

New Zealand Journal of Geology and Geophysics, Volume 69, Issue 1, March 2026.
Active fault locations and constraints on the timing and size of earthquakes are important for understanding and mitigating seismic hazard in Aotearoa New Zealand. However, historical and instrumental records are too short to provide these data on most earthquake‐generating faults. Light detection and ranging (lidar) data provide us with the ability to

Source parameters of the great Sumatran megathrust earthquakes of 1797 and 1833 inferred from coral microatolls [PDF]

, 2006
Large uplifts and tilts occurred on the Sumatran outer arc islands between 0.5° and 3.3°S during great historical earthquakes in 1797 and 1833, as judged from relative sea level changes recorded by annually banded coral heads.

Large‐Scale Deformation, Strain Characteristics, and Locking Distribution of the Qilian‐Haiyuan Fault System

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 3, March 2026.
Abstract The Qilian‐Haiyuan fault system is the main tectonic boundary of the northeastern Tibetan Plateau, controlling the regional tectonic deformation and seismic activity. Extensive Sentinel‐1 SAR data (2014–2021) are used to map the regional tectonic deformation, strain distribution, and locking along primary and secondary faults.

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

A nonlinear inversion of InSAR-observed coseismic surface deformation for estimating variable fault dips in the 2008 Wenchuan earthquake

International Journal of Applied Earth Observation and Geoinformation, 2019
Abstract Satellite Interferometric Synthetic Aperture Radar (InSAR) is playing an increasingly important role in the observation of coseismic surface deformation caused by earthquakes, and has been used to invert for subsurface fault structure and reveal earthquake source mechanisms. However, the mapping of complex non-planar or curved (e.g., listric-

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

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
