Evaluation of Porous Media Properties for the Performance of Sulfur‐Depolarized Electrolysis
ChemSusChem, Volume 19, Issue 8, 28 April 2026.Sulfur‐depolarized electrolysis (SDE) enables low‐voltage hydrogen production while converting SO2 into H2SO4. This work identifies asymmetric gas diffusion layer (GDL) designs as the key to stable operation, providing the first clear design guidelines for SDE‐tailored GDLs and lay the groundwork for the rational development of next‐generation ...

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.Abstract The absence of sound‐velocity data spanning the entire lower mantle pressures for (Fe, Al)‐bearing bridgmanite impedes direct comparisons with seismic wave observations, leaving the chemistry of the lower mantle unresolved. The present ultra‐high pressure sound‐velocity measurements of in situ synthesized (Fe, Al)‐bearing bridgmanite up to 130

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 ...

Characteristics of Seismic Energy Rate Functions of Shallow Tremors
Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.Abstract We investigated the energy rate functions of shallow tremors southeast of the Kii Peninsula in the Nankai subduction zone. Unimodal functions (triangle or bell‐shaped) explain the characteristics of small (<104 J) shallow tremors. As the seismic radiated energy increases, the energy rate functions become more complex and are better ...

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.

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.Abstract Laboratory experiments and theoretical models suggest that earthquakes are preceded by extended nucleation phases, perhaps by slow but accelerating slip. However, such nucleation phases are hard to observe before natural earthquakes. Here we identify clustered foreshock sequences that could be nucleation signatures.
