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

Geophysical 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 ...

The Effect of Hydraulic Fracturing on the 2021 Ms 6.0 Luxian Earthquake as Revealed by Deformation and Numerical Simulations

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract This study investigates whether hydraulic fracturing contributed to the 2021 Ms 6.0 Luxian earthquake in the Sichuan Basin. Time‐series InSAR analysis of multi‐temporal Sentinel‐1 data reveals coseismic deformation associated with the 2021 Luxian earthquake and localized uplift near hydraulic fracturing platforms.

Shallow Modeling and Site‐Amplification From Telecommunications Fibers in Istanbul

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract We use pre‐existing fiber‐optic telecommunications fibers in Istanbul, Türkiye, to generate a seismic velocity model of the subsurface down to 100 m depth, and estimate site‐amplification in the region. We collect ambient noise, predominantly from urban traffic, along the 8 km segment fiber, extract Rayleigh wave dispersion curves, and use a ...

Role of Unsaturated Zone on Aquifer Leakage–Assessed With Tidal Response

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract Tidal response analysis is widely used to evaluate aquifer systems, but traditional models that neglect the unsaturated zone often underestimate groundwater leakage. This study develops a new analytical model for tidal analysis that incorporates unsaturated zone effects and explained leakage patterns that traditional models could not resolve ...

Exploring the lichenization continuum through the marine tripartite symbiosis of Collemopsidium pelvetiae

American Journal of Botany, Volume 113, Issue 6, June 2026.
Abstract Premise Symbioses between lichen‐forming fungi and brown algae (phaeophytes) are extremely rare. We investigated the interactions between the marine fungus Collemopsidium pelvetiae and its two photosynthetic partners, the brown alga Pelvetia canaliculata and a cyanobacterial symbiont to address questions on symbiosis biology, lichenization ...

Effect of confining pressure on fracture characteristics and mineralogical behavior of tight sandstone specimens after hydraulic fracturing

Deep Underground Science and Engineering, Volume 5, Issue 2, Page 482-505, June 2026.
Hydraulic fracturing in tight sandstone and fracture propagation characteristics using backscattered electron‐scanning electron microscope (BSE‐SEM) images. Abstract This study focuses on hydraulic fracturing experiments conducted under triaxial conditions on tight sandstone specimens from Shivpuri district, Madhya Pradesh, India.

Failure characteristics and the energy criterion of rock with a through‐going joint under true‐triaxial unloading conditions: Insights from the DEM model

Deep Underground Science and Engineering, Volume 5, Issue 2, Page 465-481, June 2026.
The rock failure mode is significantly influenced by the contributing factors, such as the joint inclination, the initial confining pressure, and the unloading point. We found six typical rock failure modes after a large number of numerical tests. Abstract Excavation unloading damages rock masses, with preferential failure along geological defects in ...

Observations of coastal cliff landslide runout in southern California from 21 years of data

Earth Surface Processes and Landforms, Volume 51, Issue 6, June 2026.
Runout distance from coastal cliff landslides along the coast of northern San Diego County, California USA between 2001 and 2023 were mapped and quantified. Results indicated cliff height influenced runout distance, and that 98% of maximum runout distances were less than half the cliff height.
