3D P‐Wave Attenuation Tomography of the Tonga‐Lau Subduction System With Improved Earthquake Source Parameters and a Transdimensional Bayesian Markov Chain Monte Carlo Approach

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 4, April 2026.
Abstract Seismic attenuation, resulting from anelasticity of Earth's materials, provides critical information on the thermal and compositional characteristics of Earth's interior. Accurately measuring the seismic wave energy loss during propagation and conducting seismic attenuation is challenging, as conventional methods for measuring attenuation ...

Thermally Activated Static Friction Can Explain Earthquake Interactions

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 4, April 2026.
Abstract Unlike meteorological hazards, tectonic earthquakes remain hardly predictable, reinforcing their deadly character. This relates to an out‐of‐equilibrium, intermittent dynamic associated with a strong time asymmetry, with few and non‐systematic foreshocks sometimes preceding large earthquakes, while aftershocks are ubiquitous and have been ...

Solid-state mantle convection coupled with a crystallising basal magma ocean

Comptes Rendus. Géoscience
Fractional crystallisation of a basal magma ocean (BMO) has been proposed to explain the formation of large scale compositional variations in the mantle and the persistence of partially molten patches in the lowermost mantle. We present a complete set of

Three‐Dimensional Crustal Deformation Analysis Using Physics‐Informed Deep Learning

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 4, April 2026.
Abstract Earthquake‐related phenomena such as seismic waves and crustal deformation impact broad regions, requiring large‐scale 3‐D modeling with careful treatment of the boundaries of the model domain. A deep learning approach known as physics‐informed neural networks (PINNs) has potential for such large‐scale problems involving observational data ...

Autocorrelation‐Based Imaging of Crustal Discontinuities Including the Main Himalayan Thrust and Vp/Vs Ratio in the Jammu and Kashmir Himalaya

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 4, April 2026.
Abstract The Jammu and Kashmir Himalaya, located between the rupture zones of the 1905 Kangra and 2005 Kashmir earthquakes, represent a prominent “seismic gap” where understanding the subsurface structure is critical for seismic hazard assessment. This study presents new insights into the crustal structure of this region using teleseismic P‐wave coda ...

Normal Modes in a Coupled Earth Model: A New Perspective on the Compliance Method

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 4, April 2026.
Abstract To understand the compliance parameters observed for atmospheric pressure waves, we develop a normal‐mode approach for a coupled Earth model that includes the atmosphere and the solid Earth. Extending the method of Press and Harkrider to a coupled Earth model, we introduce two new features.

A Hybrid Probabilistic Framework for Mixed Discrete–Continuous Subsurface Parameter Estimation From Multi‐Physics Geophysical Data: A Case Study for Quantifying the Geofluid Mapping in the Crust and Upper Mantle

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 4, April 2026.
Abstract Joint estimation of discrete (e.g., lithology or geofluid type) and continuous (e.g., porosity, pore geometry, related connectivity) subsurface parameters represents a challenging inverse problem due to strong parameter trade‐offs, effective non‐uniqueness, and multi‐modal posterior structures.

Testing Models for Upper Mantle Earthquakes in the Tanganyika‐Rukwa Rift, Africa

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 4, April 2026.
Abstract Rifts that initiate in mechanically strong, stable continental lithosphere are characterized by M > 5 earthquakes at depths >35 km near or below the crust mantle interface. Current models for deep rift zone earthquakes invoke elevated pore pressures associated with magmatism, and rapid stressing from magma intrusions.
