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.

Fault Friction, Plate Rheology, and Mantle Torques From a Global Dynamic Model of Neotectonics

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 4, April 2026.
Abstract Improvements in software, parallel computing, global data sets, and laboratory flow‐laws help to develop the global Earth5 thin‐shell finite‐element model of Bird et al. (2008, https://doi.org/10.1029/2007jb005460) into a benchmark study. All experiments confirm that modeled faults (other than megathrusts) have low effective friction of 0.085 ±

Prolonged Hypocenter Migration in a Lower‐Crustal Earthquake Swarm in Japan: Positive Feedback Between Heat Influx and Fluid Production

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 4, April 2026.
Abstract The Yamaguchi earthquake swarm in western Japan occurred at unusually deep depths (25–40 km), well below the seismogenic zone, and exhibited prolonged zigzag hypocenter migrations over at least ∼180 days. Seismicity initiated in the southwestern part of the swarm area, followed by systematic migration eastward, northeastward, and northwestward.

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.

Variable Oceanic Crust Accretion at a Slow‐Spreading Ridge: A Vp/Vs Ratio Evidence Across the Southwest Sub‐Basin of the South China Sea

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 4, April 2026.
Abstract The opening of the Southwest Sub‐basin (SWSB) of the South China Sea was slow‐spreading and has been propagated toward the southwest. Yet, the structural variability and magmatic accretion process of the SWSB are still enigmatic. Here, utilizing a wide‐angle seismic profile traversing the central segment of the SWSB, we obtain detailed S‐wave ...
