General Framework for Multi‐Degree‐of‐Freedom Stiffness Matrix Updating for Iterative Solution Algorithms in Hybrid Simulation

open access: yesEarthquake Engineering &Structural Dynamics, Volume 55, Issue 9, Page 1947-1967, 25 July 2026.
ABSTRACT Iterative solvers are advantageous for handling nonlinear structural analysis problems. The iterative solvers often require updating the stiffness matrix, which limits their application in static and pseudo‐dynamic hybrid simulations because: (1) updating the stiffness matrix of a system involving a physical specimen is challenging; (2 ...

Digitized Stratigraphic and Geophysical Logs From Deep Boreholes in the 2022 Mw 5.5 Fano‐Pesaro Earthquake Region, Adriatic Sea, Italy

open access: yesGeoscience Data Journal, Volume 13, Issue 3, July 2026.
Legacy borehole documentation from seven deep exploration wells in the Pesaro–Fano offshore area (Adriatic Sea) was digitized into an accessible dataset of stratigraphic and geophysical data. The dataset is openly available in the Zenodo repository and supports future geological and geophysical studies in the Adriatic region and beyond.

Physics‐Supervised Autonomous Inverse Fracture Modeling via Generative Artificial Intelligence

open access: yesGeophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract Fracture networks act as critical pathways for groundwater flow and transport, yet their characterization remains challenging due to subsurface inaccessibility and stochastic complexity. Traditional inversion methods are computationally expensive and often fail to capture fracture heterogeneity accurately.

Seismic Velocity Variations Illustrate Hydrological and Ecohydrological Processes in a Mountain Watershed

open access: yesGeophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract We employ passive seismic interferometry to study seismic hydrological responses in a snowmelt‐driven, semi‐arid catchment. Seismic velocity changes (dv/v) at 2–4 Hz and 4–8 Hz are analyzed from six stations along a hillslope transect between May and November 2023 and compared to precipitation, soil moisture, and groundwater level timeseries ...

Anisotropic Biot Coefficient of Fractured Rocks Drives Failure Conditions in Pressurized Reservoirs

open access: yesGeophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract We present a theoretical framework to quantify the equivalent Biot coefficient tensor of fractured rock masses based on the properties of both the intact porous matrix and the fracture network. Our results show that the presence of dominant fracture sets produces an anisotropic equivalent Biot tensor, with larger values in the direction ...

Seismic Evidence for Slab Tearing Beneath the Indo‐Myanmar Subduction Zone

open access: yesGeophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract Slab tearing has been increasingly recognized as a key geodynamic process influencing the evolution of the eastern Himalayan syntaxis. However, whether, where and how the subducted Indian slab beneath the Indo‐Myanmar subduction zone has been torn remains poorly constrained.
