Exceptionally Elongated Strike‐Slip Rupture Caused by the 2025 MW 7.8 Myanmar Earthquake

Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract The interplay between fault geometry and rupture behavior remains poorly understood. The 2025 Myanmar earthquake ruptured the Sagaing fault, a major continental strike‐slip fault with simple geometry. We integrated geodetic and teleseismic observations to investigate its rupture process through finite‐fault kinematic inversions and back ...

Frictional Heterogeneity Governs Slip Partitioning and Seismic Hazard in the 2023 Turkey Earthquake Doublet

Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract Quantifying fault frictional properties is fundamental to understanding slip behavior and seismic hazard. We analyze 2 years of Sentinel‐1 SAR data following the 2023 Turkey earthquake doublet using Independent Component Analysis‐enhanced Small Baseline Subset‐InSAR, to resolve postseismic deformation and invert for afterslip on the East ...

Injection Induced Seismicity in Complex Fault Zone Architecture

Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract Modeling of injection‐induced seismicity plays a significant role in understanding the seismic risks associated with different anthropogenic activities including sub‐surface energy harvesting and CO2 ${\text{CO}}_{2}$ sequestration. Here we investigate multi‐cycle modeling of induced seismicity in a complex fault zone hosting a primary fault ...

New Constraints on the Calabrian Arc (Central Mediterranean) Geodynamics: High‐Resolution Imaging of Lithospheric and Upper Mantle Discontinuities From P and S Receiver Functions

Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract The Calabrian Arc subduction system (Central Mediterranean) is characterized by a deep and narrow (200 km) slab. Addressing the poorly understood link between shallow and deep mantle structures, we present the first high‐resolution mapping of crustal and upper mantle discontinuities across the Calabrian Arc and Southern Tyrrhenian basin.

Detection of Shallow Tectonic Tremors in Hyuga‐nada, Nankai Trough, Using the Newly Established N‐Net OBS Network

Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract Monitoring tectonic tremors is crucial for understanding stress release in subduction zones and assessing megathrust earthquake risk. The Hyuga‐nada region, at the western edge of the Nankai Trough, Japan, provides a natural laboratory for investigating links among slow earthquakes, megathrust events, and complex subduction structures.

Size‐Dependent Melting Behavior of Ultrafine Fault Rocks

Geophysical Research Letters, Volume 53, Issue 5, 16 March 2026.
Abstract Dynamic weakening during earthquake ruptures is essential for accommodating fault slip and controlling seismic energy release. This weakening is localized within narrow principal slip zones (PSZs) that commonly contain nanoparticles in both natural and experimental faults.

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 ...

Splay Fault Permeability Governs Fluid–Structure Interaction in Accretionary Wedges

Geophysical 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 ...
