Earthquake Source Characterization Using 3D Numerical Modeling [PDF]

, 2007
To understand the physics of earthquakes, it is important to know what happens during individual events. Dissembling the information about the source process from the recorded seismograms is a difficult and non-unique process, as there are severe trade ...

The 1886 Charleston, South Carolina, Earthquake: Relic Railroad Offset Reveals Rupture

The Seismic Record, 2023
In the absence of documented surface rupture during the 1 September 1886 Charleston earthquake, there has been considerable speculation about the location and mechanism of the causative fault.

Impacts of Transient Critical Zone Evolution on Landslide Susceptibility and Hazard Across the Utuado Batholith, Puerto Rico

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 9, September 2026.
Abstract Landscapes in humid climates often experience rapid chemical and mechanical weathering that can change groundwater fluxes, drainage pathways, and frictional strength via alterations in subsurface mineral composition and matrix porosity. These changes to hillslope critical zone structure and strength should control landslide susceptibility ...

Oblique Blind Faulting Underneath the Luzon Volcanic Arc During the 2022 Mw 7.0 Abra Earthquake, the Philippines

Geophysical Research Letters, 2023
Unknown seismogenic structures lurking beneath convergent margins introduce substantial uncertainty in seismic hazard assessments. In northwestern Luzon, the Mw 7.0 Abra earthquake on 27 July 2022 highlights the seismic activity along an unmapped blind ...

Present‐Day Kinematics of Continental Greece and Balkans Revealed by Sentinel‐1 InSAR Data

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 9, September 2026.
Abstract The Balkan Peninsula hosts the highest seismic activity in Europe, marked by numerous Mw6+ earthquakes in diverse tectonic settings. Assessing tectonic surface deformation is crucial to understand the forces controlling kinematics and, ultimately, constraining geodynamic models. However, because measuring slow velocity rates (a few mm/yr) with

Thermal and Structural Signatures Associated With Subducted Seamounts in Hyuga‐nada and Off Cape Muroto, Southwest Japan

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 9, September 2026.
Abstract We present heat flow estimates beneath the forearc slopes off Hyuga‐nada and Cape Muroto in the Nankai Trough, where the Philippine Sea plate subducts beneath the southwestern Japan. Using seismic reflection data, we identified Bottom Simulating Reflectors and derived heat flow ranging from 20 to >140 mW/m2.

Shallow segment rupture associated with the 2025 Kamchatka earthquake inferred from ALOS-2/PALSAR-2 InSAR

Earth, Planets and Space
We detected coseismic deformation associated with the 2025 Kamchatka earthquake using the Advanced Land Observing Satellite-2 (ALOS-2) ScanSAR (wide-swath) data. The coseismic deformation revealed predominantly greater than 1.5 m of eastward displacement,

The Spatiotemporal Evolution of Creep on the Southern San Andreas Fault Between 2015–2021

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 9, September 2026.
Abstract The Southern San Andreas fault (SSAF) in the Coachella Valley experiences shallow creep and slow slip events (SSE), which re‐distribute stresses in the seismogenic zone and affect the potential of future earthquakes. Although average creep rates are relatively well‐constrained, untangling the details of spatiotemporal variation in creep along ...

Interseismic Strain Accumulation and Partitioning in Hispaniola From GNSS and InSAR

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 9, September 2026.
Abstract We combine GNSS and InSAR observations to constrain the spatial distribution of strain across the northeastern Caribbean plate boundary, focusing on Hispaniola, to investigate strain partitioning and fault slip rates in an actively deforming tectonic setting with significant seismic hazard.
