Scaling of Latitude‐Dependent Heat Transport in Geostrophic Convection
Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.Abstract Latitudinal variations in heat transport shape the thermal and magnetic evolution of rapidly rotating planets, stars, and icy moons. Although global simulations have revealed strong equatorial–polar contrasts, a predictive scaling theory has been lacking.

Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.Abstract The Valles Caldera (VC), one of the largest Quaternary silicic calderas in North America, formed by explosive rhyolitic eruptions. Seismic studies suggest a crustal magmatic reservoir beneath the caldera with low‐velocity anomalies, but resolving the detailed geometry of localized melt requires constraints from seismic anisotropy.

Monitoring Near‐Surface Changes Using Anthropogenic Seismic Vibrations
Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.Abstract The abundance of anthropogenic seismic noise provides a valuable resource for monitoring dynamic subsurface property changes. We utilize railway and wind turbine‐induced vibrations recorded by a geophone array to estimate surface wave attenuation and velocity in the underlying glacial deposits of Illinois.

Insights From Two Decades of Seismicity at Columbia Glacier
Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.Abstract We use Columbia Glacier as a case study to demonstrate how seismically cataloged calving events in Alaska can track glacier evolution over two decades. By combining this catalog—a serendipitous byproduct of earthquake monitoring—with terminus positions, bathymetry, glacier thickness, surface velocity, and environmental records, we show how ...

Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.Abstract The efficacy of rapid seismic response is fundamentally constrained by the sequential, multi‐step nature of conventional InSAR processing, where error propagation and reliance on auxiliary data hinder automation. Here, we present a holistic framework using Physics‐Aware Generative Adversarial Networks (GANs) to directly retrieve absolute ...

Sub‐Wavelength Seabed Stiffness Control of Seismic Amplitude Modulation in Seafloor DAS
Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.Abstract Submarine distributed acoustic sensing cables record seafloor strain with striking spatial variability whose physical origin is not immediately obvious. By explicitly partitioning the recorded wavefield into ocean‐wave, Scholte‐wave, and teleseismic Rayleigh‐wave components, we show that these amplitude variations are not random but encode ...

Geophysical Research Letters, Volume 53, Issue 5, 16 March 2026.Abstract Landslides often generate long‐period seismic waves that propagate over large distances. During volcanic island collapses and their intrusion into seawater, seismic signals of >1 min periods are widely observed. The physical sources of these signals remain poorly understood due to complex landslide‐water interactions. In this paper, we perform

Decadal Stability of Multi‐Scale Core‐Mantle Boundary in Core‐Reflections of Repeating Earthquakes
Geophysical Research Letters, Volume 53, Issue 5, 16 March 2026.Abstract Temporal changes near the core‐mantle boundary (CMB) would trigger insights into ongoing thermal and chemical interactions between the Earth's core and mantle. Here, we search for multidecadal temporal changes in the CMB topography and heterogeneity using waveform similarity analysis of core‐reflected phases (PcP, ScP, and ScS) from global ...

Geophysical Research Letters, Volume 53, Issue 5, 16 March 2026.Abstract As global climate change intensifies, hurricane‐induced storm surges are becoming more frequent and severe. While Global Navigation Satellite System‐Interferometric Reflectometry (GNSS‐IR) is widely used to monitor sea level variations, its capability to detect rapid and extreme events remains limited.
