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

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 ...

Meltwater Orientations Modify Seismic Anisotropy in Temperate Ice
Geophysical Research LettersSeismology is increasingly used to infer the magnitude and direction of glacial ice flow. However, the effects of interstitial meltwater on seismic properties remain poorly constrained.

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.

Adsorption Preceding Wetting Front Controls Seismic Velocity
Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.Abstract Rock elasticity varies with both humidity and water saturation, yet their combined effects remain poorly understood, although in nature vapor adsorption and liquid infiltration occur simultaneously. Here, we present experimental data of P‐wave velocity and volume expansion in a free‐standing sandstone subject to progressive wetting.
