Journal of Geophysical Research: Earth Surface, Volume 131, Issue 4, April 2026.Abstract Landslides represent one of the most devastating natural hazards in mountainous regions, posing significant threats to human safety, infrastructure and ecosystems. It is well established that there is a connection between meteorological factors and landslide occurrences but the mechanisms of these interactions and the impacts of climatic ...

Self-gravity, self-consistency, and self-organization in geodynamics and geochemistry [PDF]
, 2005 The results of seismology and geochemistry for mantle structure are widely believed to be discordant, the former favoring whole-mantle convection and the latter favoring layered convection with a boundary near 650 km.

Rates of Sea‐Level Rise Are Highly Sensitive to Ice Viscosity Parameters in Model Benchmarks
AGU Advances, Volume 7, Issue 2, April 2026.Abstract Glacier flow plays a major role in current and future rates of globally averaged sea‐level rise. The viscosity of glacial ice, controlling the rate of flow, decreases as stress increases and is highly sensitive to the value of the stress exponent, n $n$, in the constitutive equation for viscous flow.

Pressure Dependence of Liquid Iron Viscosity From Machine‐Learning Molecular Dynamics
Geochemistry, Geophysics, Geosystems, Volume 27, Issue 4, April 2026.Abstract We have developed a machine‐learning potential that accurately models the behavior of iron under the conditions of Earth's core. By performing numerous nanosecond scale equilibrium molecular dynamics simulations, the viscosities of liquid iron for the whole outer core conditions are obtained with much less uncertainty.

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 ...

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.

, 2018 We present a new rheological model depending on a real parameter $\nu \in [0,1]$ that reduces to the Maxwell body for $\nu=0$ and to the Becker body for $\nu=1$.

Thermally Activated Static Friction Can Explain Earthquake Interactions
Journal of Geophysical Research: Solid Earth, Volume 131, Issue 4, April 2026.Abstract Unlike meteorological hazards, tectonic earthquakes remain hardly predictable, reinforcing their deadly character. This relates to an out‐of‐equilibrium, intermittent dynamic associated with a strong time asymmetry, with few and non‐systematic foreshocks sometimes preceding large earthquakes, while aftershocks are ubiquitous and have been ...

A Restoration Method for Impulsive Functions [PDF]
, 1977 A method is presented for enhancing the resolution of impulsive functions which have been degraded by a known convolutional disturbance and by the addition of white noise.

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 4, April 2026.Abstract Earth's long period background seismic wavefield is dominated by two distinct processes that couple ocean wave energy to a global microseism wavefield. We assess global microseism intensity in the secondary (4–10 s) and primary (14–20 s) bands, and across eight 2 s‐wide period bands between 4 and 20 s.
