Upper Mantle Heterogeneity and Weak Subduction Boundaries Control Crustal Stress in the Korean Peninsula

open access: yesGeophysical Research Letters, Volume 53, Issue 5, 16 March 2026.
Abstract Most earthquakes occur at plate boundaries, but some also strike within stable continental interiors. Although dominant causes of such intraplate earthquakes remain elusive, a prevailing hypothesis attributes intraplate stress and seismicity to variations in lithospheric thickness.

Decadal Stability of Multi‐Scale Core‐Mantle Boundary in Core‐Reflections of Repeating Earthquakes

open access: yesGeophysical 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 ...

Monitoring of the Transient Sea Level Variations Associated With Hurricane‐Induced Storm Surges by GNSS‐IR

open access: yesGeophysical 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.

Splay Fault Permeability Governs Fluid–Structure Interaction in Accretionary Wedges

open access: yesGeophysical Research Letters, Volume 53, Issue 5, 16 March 2026.
Abstract Interactions between upper plate deformation and plate interface seismicity in subduction zones remain poorly understood, but growing evidence indicates that fluid flow along splay faults modulates upper‐plate faulting. Field observations from two exhumed splay faults define end‐member scenarios where impermeable faults trap fluids in their ...

Anisotropic Melt Inclusions as a Confounding Signal for Ice‐Penetrating Radar Observations

open access: yesGeophysical Research Letters, Volume 53, Issue 5, 16 March 2026.
Abstract Ice‐penetrating radar is a powerful geophysical tool for understanding the subsurfaces of Earth, Mars, and icy moons. Radar reflectivity, attenuation, and birefringence are used to infer subsurface hydrology, englacial temperature, water content, and crystal orientation fabric.
