River Sand and Gravel Mining: Global Drivers, Impacts, and Pathways for Sustainable Management

Reviews of Geophysics, Volume 64, Issue 3, September 2026.
Abstract River sand and gravel are mined worldwide at volumes that now rival their natural replenishment, yet quantitative knowledge of this mining activity and its consequences lags far behind many other global environmental pressures. We synthesize 411 peer‐reviewed studies published since 1974 within a new Driver‐to‐Management Pathway for ...

An Operational Daily‐Filtered Dominion Radio Astrophysical Observatory F10.7 cm Solar Radio Flux Product

Earth and Space Science, Volume 13, Issue 9, September 2026.
Abstract The F10.7 solar radio flux density, or F10.7, is a disk‐integrated measure of the Sun's total emission at 10.7 cm (2.8 GHz) and is a widely‐used proxy of solar activity. F10.7 emissions primarily originate from the Sun's upper chromosphere and lower corona. High‐frequency, transient “radio bursts” can dramatically increase the magnitude of F10.

Assessing SWOT's Measurement Capabilities in the Complex Paraná River

Earth and Space Science, Volume 13, Issue 9, September 2026.
Abstract Estimating water surface elevation (WSE) is crucial for understanding hydrological processes; however, many rivers remain insufficiently monitored due to the limitations of in situ gauge networks. The Surface Water and Ocean Topography (SWOT) mission, equipped with Synthetic Aperture Radar technology, enables global monitoring of WSE with high

Mechanisms of Transient Postseismic Deformation Following the 2024 Mw 7.5 Noto Peninsula Earthquake Inferred From Horizontal and Vertical GNSS Data

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 9, September 2026.
Abstract The 2024 Mw 7.5 Noto Peninsula earthquake provided an opportunity to investigate postseismic deformation in a tectonically complex back‐arc region in central Japan, where Miocene normal faults are reactivated under present‐day compression.

Mapping the Crustal Thickness of the Andes Using pmP Phases Identified From Adaptive Teleseismic Array Data

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 9, September 2026.
Abstract Crustal thickness (or Moho depth) is a key parameter for many geological and geophysical models. Despite this we have a limited number of measurements, typically from seismic receiver functions, to constrain variations in crustal thickness.

Detection of Interannual and Fine‐Scale Plate Coupling Variations Using Intraplate Earthquakes and Geodetic Data: Application to the Tohoku‐Oki Plate Boundary

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 9, September 2026.
Abstract We propose a method to infer detailed spatiotemporal variations in interplate coupling by integrating geodetic and seismic data. It examines whether focal mechanisms of intraplate earthquakes occurring near the plate interface align with the stressing rates caused by a geodetically derived slip‐deficit rate model, evaluating deviations from a ...

Characterization of the Plumbing System Beneath Askja Caldera, Iceland, Revealed by Microgravity and Deformation Data During Uplift Between 2022 and 2023

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 9, September 2026.
Abstract In July 2021, an episode of uplift started at Askja caldera, Iceland, following over 50 years of subsidence. The initial inflation rate was approximately 700mm/yr $700\hspace*{.5em}\mathrm{m}\mathrm{m}/\mathrm{y}\mathrm{r}$, declining to 350mm/yr $350\hspace*{.5em}\mathrm{m}\mathrm{m}/\mathrm{y}\mathrm{r}$ within 1 month.

Imaging the Alpine Collision With Seismic Radial Anisotropy

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 9, September 2026.
Abstract The Alpine region and the adjacent Northern Apennines (NA) and Northern Dinarides record the complex tectonic evolution associated with the collision between the Eurasian and Adriatic plates. We combine Rayleigh and Love surface waves from ambient noise and earthquake data recorded at over 3,300 seismic stations to construct a high‐resolution ...

GIA‐Induced Mantle Circulation and Surface Horizontal Motions in North America: Effects of 3D Laterally Varying Elastic Thickness and Viscosity

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 9, September 2026.
Abstract The horizontal surface motions of the Earth's crust induced by glacial isostatic adjustment (GIA) are highly sensitive to lateral variations in Earth properties. We construct 3D GIA models by incorporating both varying elastic lithospheric thickness and lateral viscosity variations in the asthenosphere in a global, compressible, self ...
