Earth's Lower Mantle Predominated by Ferric Iron‐Rich Bridgmanite Inferred From High Pressure Elasticity Measurements

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

On the Application of 1 Versus 2 State Variable Rate‐and‐State Friction Laws: An Example From the Nankai Trough Megasplay Fault Zone

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract Frictional slip behavior in fault zones can be analyzed with friction laws using 1 or 2 state variables, but the physical meaning and applicability of the 2‐state variable form of the law remain unclear. Here, we re‐analyze friction experiments by Roesner et al. (2022, https://doi.org/10.1186/s40623‐022‐01728‐w) using a natural sample from the

Rapid Land Surface Uplift and Groundwater Recovery Observed During the Syrian War

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract Recent geopolitical upheaval in Syria is driving regional growth by returning populations, which increases demands on water resources. In northwest Syria, widespread cropland abandonment during the Syrian War starting in 2011 drastically changed the hydrological regime of the region.

Observing Broadband Tsunamis in Deep Water Via Distributed Acoustic Sensing

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract Tsunamis have been detected as strain variations in optical fibers of submarine cables through distributed acoustic sensing (DAS). However, the usefulness of strain variations during tsunamis for early warning remains unclear. Here, we compare fiber strains and sea‐level changes for both infragravity waves in ambient noise and tsunamis ...

Revealing the Mechanisms of Heat Extremes Using an AI Enabled Diagnostic Framework

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract Heat extremes have become a major health hazard around the world. Understanding their mechanisms remains a major challenge because the physical drivers interact in a nonlinear way. Here we introduce a globally perturbed reforecast framework driven by the Neural general circulation model (NeuralGCM).
