Differential Mountain‐Building in the South Tian Shan Revealed by Multi‐Spatiotemporal Foreland Deformation

Tectonics, Volume 45, Issue 2, February 2026.
Abstract Understanding how spatially variable mountain‐building processes proceed within large intracontinental orogens provides critical insights into continental tectonics and regional paleoenvironmental evolution. Here, we address this issue in the central South Tian Shan (cSTS), a key transitional segment between the well‐studied eastern and ...

Inner forearc faults in northern Cascadia do not accommodate elastic strain driven by the megathrust seismic cycle

Seismica
We employ numerical models to explore the connection between subduction zone coupling or megathrust rupture and upper plate faults in the northern Cascadia forearc.

Residual polar motion caused by coseismic and interseismic deformations from 1900 to present [PDF]

Geophysical Journal International, 2016
We challenge the perspective that seismicity could contribute to polar motion by arguing quantitatively that, in first approximation and on the average, interseismic deformations can compensate for it. This point is important because what we must simulate and observe in Earth Orientation Parameter time-series over intermediate timescales of decades or ...

Extreme Winter Precipitation Drives Recharge of Mountain Groundwater in the Sierra Nevada and Cascades of the Western United States

Water Resources Research, Volume 62, Issue 2, February 2026.
Abstract Groundwater flowing within mountainous regions is a critical water source for mountain and adjacent low‐elevation communities and ecosystems. Despite their importance, quantifying storage changes within these groundwater systems remains a challenge.

Interseismic crustal deformation in and around the Atotsugawa fault system, central Japan, detected by InSAR and GNSS

Earth, Planets and Space, 2018
The Atotsugawa fault system is one of the best-known active faults in Japan. However, revealing the interseismic velocity field in and around the Atotsugawa fault system with high spatial resolution is challenging because of dense vegetation, steep ...

Permeability Enhancement by Slow Faulting Under High Pore Fluid Pressure

Geophysical Research Letters, Volume 53, Issue 2, 28 January 2026.
Abstract The morphology of fault zones formed by slow faulting is markedly different from that of brittle faulting. In this study, we quantify the three‐dimensional (3D) pore distribution and permeability structures of two rock samples that have been deformed to failure by slow and brittle faulting, respectively.

Decomposing DInSAR Time-Series into 3-D in Combination with GPS in the Case of Low Strain Rates: An Application to the Hyblean Plateau, Sicily, Italy

Remote Sensing, 2017
Differential Interferometric SAR (DInSAR) time-series techniques can be used to derive surface displacement rates with accuracies of 1 mm/year, by measuring the one-dimensional distance change between a satellite and the surface over time.

Rupture Dynamics of the 2025 Mw 7.7 Myanmar Earthquake: A Bilateral Supershear Rupture on Unusually Long Fault Superhighway

Geophysical Research Letters, Volume 53, Issue 1, 16 January 2026.
Abstract The 2025 Mw 7.7 Myanmar earthquake ruptured the central Sagaing fault, a previously identified seismic gap with high seismic potential. Here, we perform hundreds of 3D dynamic rupture simulations to investigate the rupture dynamics, constrained by near‐fault strong‐motion waveforms, optical and SAR pixel offsets, and a kinematic source model ...

Inelastic deformation accrued over multiple seismic cycles: Insights from an elastic-plastic slider-and-springboard model

Seismica
We study a toy model designed to build physical insight into the problem of slow accumulation of non-recoverable strain in fault blocks over multiple earthquake cycles.

Soil Gas Investigations in Hatay‐Reyhanlı (Türkiye): Implications for Buried Fault Detection and Seismic Hazard Assessment

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 1, January 2026.
Abstract This study presents a soil gas geochemical survey in the Kırcaoğlu and Reyhanlı regions of Hatay Province, southeastern Türkiye, following the 2023 Kahramanmaraş earthquake doublet. The aim was to identify concealed faults and assess seismic hazard through analysis of soil CO2 flux, CO2 and 222Rn concentrations, and carbon and helium isotopic ...
