State of Stress Across Major Faults in the Nankai Subduction Zone Estimated From Wellbore Breakouts

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 7, July 2025.
Abstract Quantifying the orientation and magnitude of stress at tectonically active margins and along major fault systems is integral to understanding the mechanics of faulting and earthquakes. Here we use data collected as part of the IODP (Integrated Ocean Drilling Program) Nankai Trough Seismogenic Zone Experiment to constrain in situ stress ...

The Effect of Edifice Slope, Failure Surface Geometry, and Magma Intrusion Depth on the Development of Flank Instability at Volcanoes

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 7, July 2025.
Abstract Magmatism is a known driver of flank instability at volcanoes where flank slip has been observed. Studies of instability at Kı̄lauea, Piton de la Fournaise, and Etna imply that long‐term flank motion likely requires the presence of a layer accommodating the sliding, and a force, such as magma intrusion, that promotes slip.

Energy partitioning during an earthquake [PDF]

, 2006
We investigate the partitioning of energy released during an earthquake to radiated, fracture and thermal energies in an attempt to link various observational results obtained in different disciplines.

Spontaneous Initiation and Evolution of Polygonal Fault Systems During the Early Burial of Sediments in 3D Numerical Models

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 7, July 2025.
Abstract Polygonal Fault Systems (PFS) or networks were generated in 3D finite‐difference models within the upper (active) layer of two‐layer model. The driving force of this process results from a progressive diagenetically induced volumetric contraction (porosity reduction) of the active layer during its burial.

The 5 April 2024 Mw ${\mathrm{M}}_{\mathrm{w}}$4.8 Tewksbury, New Jersey Aftershock Sequence Resolved With Machine‐Learning‐Enhanced Detection Methods

Geophysical Research Letters, Volume 52, Issue 12, 28 June 2025.
Abstract The Ramapo Seismic Zone (RSZ) in the Northeastern United States hosts frequent but poorly understood intraplate earthquakes, potentially posing a significant hazard to the nearby New York metropolitan area. The 5 April 2024, Mw ${M}_{w}$4.8, Tewksbury, New Jersey earthquake, provides a rare opportunity to study the RSZ seismicity.

A comprehensive study on in situ stress field characteristics and changes in rock mechanical properties in deep mines in northeastern Yunnan, China

Deep Underground Science and Engineering, Volume 4, Issue 2, Page 241-254, June 2025.
This paper studies the distribution characteristics of the current in situ stress field in northeast Yunnan Province by using multisource stress data, including in situ stress measurements, focal mechanism solutions, and borehole damage information, and comprehensively determines the in situ stress magnitude and direction in the mining area.

Shallow Fault Zone Structure Affects Rupture Dynamics and Ground Motions of the 2019 Ridgecrest Sequence to Regional Distances

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 6, June 2025.
Abstract Seismic faults are surrounded by damaged rocks with reduced rigidity and enhanced attenuation. These damaged fault zone structures can amplify seismic waves and affect earthquake dynamics, yet they are typically omitted in physics‐based regional ground motion simulations.

A Stress Memory Effect in Olivine at Upper Mantle Pressures and Temperatures

Geophysical Research Letters, Volume 52, Issue 9, 16 May 2025.
Abstract Cyclic deformation experiments on olivine aggregates have been conducted at pressures of 1.9–2.8 GPa and temperatures of 297–1250 K. Measurements of mechanical data combined with acoustic emission (AE) monitoring revealed that activity of AE increased with differential stress and ceased once loading was halted in the anelastic regime.
