Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.Abstract Recent advances in deep learning have transformed seismic monitoring, yet most existing methods remain task‐specific and data‐limited, restricting performance on challenging scenarios and generalization to unseen data. Large‐scale pretraining has addressed similar limitations in other fields, but its application to seismic data faces ...

Al2O3 in Anorthositic Slabs: A New Perspective on LLSVPs and Seismic Velocity Variations
Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.Abstract Aluminum is a key component of crustal and mantle minerals, influencing melting and geochemical evolution within the Earth. Al2O3 exists as corundum at the surface and in upper mantle conditions, but transforms into high‐pressure phases like Rh2O3(II) at lower mantle depths, enabling stability over a wide pressure range.

The Role of Fluids in Fault Mechanics: A 16‐Year Analysis of the Irpinia Seismicity (Southern Italy)
Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.Abstract Fluids in the crust influence earthquake nucleation by affecting fault strength and rupture dynamics, but direct observations at seismogenic depths are rare. We study the Irpinia Fault System in Southern Italy, site of the 1980 M 6.9 earthquake, to understand how fluid overpressure, fault orientation, and regional stress control earthquake ...

How Volume Increases the Mobility of Geophysical Granular Flow: A Unified Rheological Perspective
Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.Abstract Geophysical granular flows, involving rapidly flowing granular materials, can exhibit volume‐enhanced mobility. Lacking a mechanistic understanding of such size effects limits the applications of lab‐scale findings to natural events. Using discrete element method simulations, we find that increasing granular system size suppresses energy ...

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.Abstract At frequently erupting volcanoes, magma and volatiles ascend through established pathways, but the complete picture of their branching and supply system remains unclear. We integrated self‐potential (SP), broadband magnetotelluric (MT), and helium isotope observations to image magma and volatile pathways beneath Sakurajima Volcano.

Layered Seismic Anisotropy and Tectonics of the Anatolian Plate
Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.Abstract Anatolian tectonics are associated with slab retreat in the west and gravitational potential energy and continental collision in the east, leading to westward motion of Anatolia relative to Eurasia, partially accommodated on the North and East Anatolian transform faults.

Partial Ruptures, Cascading Multi‐Fault Ruptures, and Aftershocks in 2D Random Fault Network
Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.Abstract The Gutenberg‐Richter law for the distribution of earthquake magnitude and the Omori law for the decay of aftershocks are two universal laws in seismicity. Although numerical models have been developed to reproduce these laws, they sometimes produce many more foreshocks and fewer aftershocks than observed.

Full Waveform Inversion for Time-Distance Helioseismology
, 2014 Inferring interior properties of the Sun from photospheric measurements of the seismic wavefield constitutes the helioseismic inverse problem. Deviations in seismic measurements (such as wave travel times) from their fiducial values estimated for a given

Trench‐Breaching Rupture of the 2025 Mw 8.8 Kamchatka Earthquake and How It Repeats the 1952 Event
Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.Abstract The 29 July 2025 Mw 8.8 Kamchatka earthquake generated a trans‐Pacific tsunami. The hypocenter was nearly at the same location as the 1952 great earthquake (Mw 8.8–9.0). Determining whether the 2025 rupture reached the trench and how it relates to the 1952 event is crucial for understanding slip behavior along the Kamchatka subduction zone. We

Dynamic inverse problem in a weakly laterally inhomogeneous medium [PDF]
, 2005 An inverse problem of wave propagation into a weakly laterally inhomogeneous medium occupying a half-space is considered in the acoustic approximation. The half-space consists of an upper layer and a semi-infinite bottom separated with an interface.
