Analysis and Optimization of Early‐Warning Indicators for Impact Critical Stress in Deep Soft Coal Seams

Energy Science &Engineering, EarlyView.
This study determines the impact critical stress early‐warning indicators for deep soft coal seams: 18 MPa (shallow holes), 20 MPa (deep holes), and 3 MPa/d daily stress change rate, via theoretical, experimental and simulation methods. ABSTRACT The accurate determination of early‐warning indicators for critical impact stress in deep soft coal seams is

Observational Evidence of a Very‐Low‐Frequency Earthquake (Mw 3.8) Leading to an Earthquake (Mw 4.2): Minto Flats Strike‐Slip Fault Zone, Central Alaska

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract The physical conditions governing earthquake initiation are largely unknown, particularly in the minutes to seconds preceding rupture. While there is geodetic and seismic evidence of precursory activity in the hours to weeks prior to large earthquakes, the observational evidence immediately preceding the earthquake rupture is limited and ...

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.

Integrated Geophysical Imaging Reveals the Origin and Pathways of Mantle‐Derived CO2 Beneath the Tangra Yumco Rift, Central Tibet

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract The Tangra Yumco Rift (TYR) in central Tibet is a key window for crust–mantle interactions during extension. We performed high‐resolution crust‐mantle imaging using receiver function analysis, 1‐D nonlinear S‐wave velocity inversion, and tomoDD tomography, revealing a vertical Crust–Mantle Degassing System (CMDS) bounded by the Zhala (ZF) and ...

Study on the Influence of Slope Static Load on Shallow Lining Support Structure

Energy Science &Engineering, Volume 14, Issue 6, Page 2721-2735, June 2026.
On the basis of the background of the shallow‐buried main adit supported by stone lining, the mechanical model of the supporting structure is constructed, and the stability of the supporting structure is analyzed by using the methods of field investigation, theoretical analysis, and numerical simulation.

Interpretable Tree‐Based Models for Predicting Short‐Term Rockburst Risk Considering Multiple Factors

Energy Science &Engineering, Volume 14, Issue 6, Page 2941-2960, June 2026.
Interpretable tree‐based models integrate microseismic, geological, and mining indicators to predict short‐term rockburst risk. SHAP analysis reveals the dominant role of energy‐related features and clarifies nonlinear factor interactions, enabling transparent and reliable early‐warning in deep coal mines.

Four Phenomena Observed on Microseismic Data

, 2013
Passive seismic data recorded in observation wellbores for hydraulic fracture monitoring are usually used to detect P- and S-wave arrivals from induced microseismic events. The time arrivals for these events are used to compute source locations to build a fracture location map.

New Insights Into Hikurangi Subduction Inputs and Megathrust Host Rocks Spanning Along‐Margin Changes in Fault Slip Behavior

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 6, June 2026.
Abstract The seismic behavior of subduction megathrusts varies spatially and is influenced by the properties of subducting plates, including their sedimentary cover. Characterizing these subduction inputs is essential for understanding the mechanisms behind fault slip variability.

Rift Development, Tectonic Forcings, and Magmatic Feedbacks at Santorini and Kolumbo Volcanoes Constrained by Scientific Drilling and Core‐Seismic Integration

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 6, June 2026.
Abstract Volcanism in continental rifts, rifted volcanic arcs, and back‐arc basins is fundamentally coupled with crustal extension. However, the precise geometry and timing of the fault systems that facilitate magma transport and accommodate extension remain poorly constrained.

The Seismic Signature of the Atlantis Massif Oceanic Detachment Fault Determined From Crystallographic Preferred Orientation and Microstructure

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 6, June 2026.
Abstract At slow‐spreading mid‐ocean ridges large scale detachment faults partly accommodate the spreading process. The mafic and ultramafic rocks at the ridges are infiltrated by water and change their mineralogy. Subsequently or contemporaneously to these reactions, detachment faulting takes place.
