Fault Volume Digital Twin to Reproduce the Full Slip Spectrum, Scaling, and Statistical Laws

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 5, May 2026.
Abstract Seismological and geodetic observations of fault zones reveal diverse slip dynamics, scaling, and statistical laws. Existing mechanisms explain some but not all of these behaviors. We show that incorporating an off‐fault damage zone—characterized by distributed fractures surrounding a main fault—can reproduce many key features observed in ...

Forecasting the Rate of Induced Seismicity as a Neural Temporal Point Process

Journal of Geophysical Research: Machine Learning and Computation
Forecasting is an essential part of risk mitigation, where the mitigation efficacy depends strongly on the quality of forecasts. We explore the neural temporal point process as a deep learning framework to forecast induced earthquakes.

Lateral Variations in Lunar Crustal Thickness Inferred From Apollo Seismic and GRAIL Gravity Data

Journal of Geophysical Research: Planets, Volume 131, Issue 5, May 2026.
Abstract The internal structure of the Moon is key to understanding its formation, evolution, and bulk composition. In particular, determining the structure of the crust–mantle interface (Moho), including its lateral variations, is of significant importance, but current knowledge is still insufficient to fully constrain it.

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

Standing Slow-Mode Waves in Hot Coronal Loops: Observations, Modeling, and Coronal Seismology

, 2010
Strongly damped Doppler shift oscillations are observed frequently associated with flarelike events in hot coronal loops. In this paper, a review of the observed properties and the theoretical modeling is presented.

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 ...

Probabilistic estimation of the source component of seismic hazard in North-Eastern Brazil

Heliyon
Stable continental regions pose unique challenges for conducting Probabilistic Seismic Hazard Analysis because the earthquake activity driving mechanisms are poorly understood.

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.
