Fluid‐Driven Cohesive Strengthening: Critical Role of Reaction Kinetics as the Determinant for Frictional Stability

AGU Advances, Volume 7, Issue 3, June 2026.
Abstract Following an earthquake, faults lock and regain strength via a combination of healing mechanisms that include pressure solution, contact growth, and cementation. Fault healing dictates strength recovery during the seismic cycle and is therefore a key factor controlling earthquake recurrence intervals, stress drop, and other source properties ...

Deep‐Seated Landslide Stability on Curved Basal Surfaces With and Without Glacier Buttressing

Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract Glacial retreat influences landslide dynamics, yet the controls on stability and transient acceleration remain unclear. We develop a two‐dimensional mechanical model of landslides with curved basal surfaces, Mohr‐Coulomb friction, and ice buttressing.

Generalised Kinematic Single‐Impact and Multi‐Impact Models for Rocking Structures

Earthquake Engineering &Structural Dynamics, Volume 55, Issue 6, Page 1179-1202, May 2026.
ABSTRACT The rocking motion is fundamental in earthquake engineering, as it reflects the dynamic behaviour of many structural systems. However, simulating the impacts during rocking motion remains a challenging topic, as they occur in a very short time, generate high impulsive forces, cause sudden changes in velocities and result in rapid energy losses.

Intrusion of wedge in the half-space under the Coulomb–Mohr yield criterion

Vestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2007
The problem of wedge intrusion in the half-space was considered by R. Hill, E. Lie, and S. Tupper under the Mises yield criterion and Tresca yield criterion. In this case the perfect plastico-rigid body is incompressible.

Stress Model of California: Fault‐Stress Interactions Across a Complex Plate Boundary System From Focal Mechanisms of Small Earthquakes

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 5, May 2026.
Abstract California, located along the transform boundary between the Pacific and North American plates, hosts a complex fault system, a long history of damaging earthquakes, and frequent small earthquakes. While earthquakes arise from the buildup and release of elastic stress, detailed knowledge of principal stress orientations, absolute stress ...

Unraveling the Mystery of Melt Migration in Migmatites: From Channeling Instability to Pattern Formation

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 5, May 2026.
Abstract Melt migration in partially molten rocks is commonly described by porous flow models controlled by the hydro‐mechanical compaction length, which effectively explains melt extraction at mid‐ocean ridges. However, this framework cannot account for the paradoxical accumulation of small melt fractions into rhythmic leucosome–melanosome bands in ...

A Fractal-Enhanced Mohr–Coulomb (FEMC) Model for Strength Prediction in Rough Rock Discontinuities

Fractal and Fractional
Accurate prediction of the shear strength of rock discontinuities requires accounting for surface roughness, which is a factor neglected in the classical Mohr–Coulomb criterion.

Assessing the Spatiotemporal Variability in Geotechnical Sediment Properties of Beach Cusps on a Sandy Beach

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 5, May 2026.
Abstract This study examined the spatiotemporal variability in geotechnical properties of beach cusp sediments on a sandy beach and tested if such variability can be used for cusp monitoring from satellite imagery. Specifically, sediment properties (including moisture content (w), relative density (Dr), sediment strength (QSBC) and friction angle (ϕ ...
