A Rate‐and‐State Friction Based Criterion for the Probability of Earthquake Fault Jumps

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 4, April 2026.
Abstract Geometrical complexities in natural fault zones, such as steps and gaps, pose a challenge in seismic hazard studies as they can act as obstacles to seismic ruptures. In this study, we propose a criterion, which is based on the rate‐and‐state equation, to estimate the efficiency of an earthquake rupture to jump between two spatially ...

Robust Directional Analysis of Magnetic Microscopy Images Using Non‐Linear Inversion and Iterative Euler Deconvolution

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 4, April 2026.
Abstract In paleomagnetism, bulk measurements of entire samples have traditionally been used to characterize remanent magnetization. While effective, this approach provides only a general directional estimate and cannot resolve spatial variability or magnetization at the grain scale.

Different Radiation Characteristics Between Foreshocks and Aftershocks of the 2016 Mw7.0 Kumamoto Earthquake in Kyushu, Japan: Implication of Pore Pressure, Stress Concentration, and Loading Rate

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 4, April 2026.
Abstract We estimated the scaled energy (eR ${e}_{R}$) for small earthquakes (1.5≤Mjma≤3.0 $1.5\mathit{\le }{M}_{\text{jma}}\mathit{\le }3.0$) in the focal area of the 2016 Mw 7.0 Kumamoto earthquake to examine the underlying physical processes governing the foreshocks‐mainshock‐aftershock sequence.

The 2004 and 2005 Sumatra Earthquakes: Implications for the Lisbon earthquake [PDF]

, 2005
The Sumatra mega-earthquake of 26 December 2004 (Mw=9.3) was the strongest earthquake in the world since the 1964 Alaska earthquake and the fifth strongest since 1900. The earthquake occurred at the interface of the India and Burma plates and triggered a

Holocene Normal Faulting in the Southern Rocky Mountain Trench; Orogenic Collapse Modulated by Glacial Unloading?

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 4, April 2026.
Abstract The Southern Rocky Mountain Trench (SRMT) is a conspicuous valley in the eastern Canadian Cordillera. It lies above a sharp change in lithospheric strength and thickness and is occupied by a normal fault thought to have last been active in the Eocene.

Deformation and Earthquake Potential on the North America–Caribbean–Cocos Plate Boundary System in Guatemala

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 4, April 2026.
Abstract In Guatemala, the Cocos, North American, and Caribbean plates interact to create a region of high seismic risk. Previous analyses of crustal faults in the country have been overly simplified, creating discrepancies between geologic and geodetic slip rate models.

Autocorrelation‐Based Imaging of Crustal Discontinuities Including the Main Himalayan Thrust and Vp/Vs Ratio in the Jammu and Kashmir Himalaya

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 4, April 2026.
Abstract The Jammu and Kashmir Himalaya, located between the rupture zones of the 1905 Kangra and 2005 Kashmir earthquakes, represent a prominent “seismic gap” where understanding the subsurface structure is critical for seismic hazard assessment. This study presents new insights into the crustal structure of this region using teleseismic P‐wave coda ...

Normal Modes in a Coupled Earth Model: A New Perspective on the Compliance Method

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 4, April 2026.
Abstract To understand the compliance parameters observed for atmospheric pressure waves, we develop a normal‐mode approach for a coupled Earth model that includes the atmosphere and the solid Earth. Extending the method of Press and Harkrider to a coupled Earth model, we introduce two new features.

The Late Miocene Southern and Central Taranaki Inversion Phase (SCTIP) and related sequence stratigraphy and paleogeography [PDF]

, 2008
We present a new sequence stratigraphic scheme for Taranaki Basin that identifies four 3rd order duration (3 - 4 m.y.) sequences of Middle Miocene to Pleistocene age.

Mantle Dynamic Topography of the Fringing Oceanic Basins of Antarctica

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 4, April 2026.
Abstract Dynamic mantle processes are known to influence oceanic basins with implications for ocean circulation and climate. This study exploits an interdisciplinary approach to probe present‐day mantle and lithosphere beneath Antarctica's fringing oceanic basins to better understand sub‐crustal processes and implications for the continental realm.
