Active Hydrothermal Hydrogen Emissions in Continental Collision Settings: Insights From the Southeastern Tibetan Plateau

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 7, July 2026.
Abstract Natural hydrogen (H2) is a promising clean energy resource and a significant component of geothermal gases, yet its origins and release mechanisms remain poorly constrained. Here, we present geochemical and isotopic data (CO2, N2, Ar, H2, He, CH4, 3He/4He, δ13C‐CO2, and δ13C‐CH4) for hydrothermal gases from the Changning–Menglian suture (CMS),

Mine microseismic and electrical coupling monitoring technology [PDF]

With the increase of the depth, mining intensity and area of coal resource, the mining disturbances in the mining face can easily induce mine water inrush accidents, seriously threatening the safe mining of coal resources in China.

The Role of Crustal Rheology and Mantle Fluids on the Interseismic Behavior of the Main Marmara Fault

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 7, July 2026.
Abstract Faults can release tectonic loading either in the form of seismic events or via aseismic creep. The Main Marmara Fault (MMF) in the Sea of Marmara exhibits both locked and creeping behavior and poses a significant hazard to the megacity of Istanbul.

Block Kinematics, Interseismic Coupling and Fault Slip Rates in the Aegean Region From GPS and Earthquake Slip Vector Data: 1. Upper Plate Structures

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 7, July 2026.
Abstract We represent the active deformation of the Aegean region with an elastic‐kinematic block model composed of a finite number of rotating crustal blocks whose boundaries coincide with major active structures. A total of 832 GPS velocities and 146 earthquake slip vectors were inverted to provide estimates of block rotations and interseismic ...

New Constraints on Active Normal Faulting in the South Gulf of Evia, Greece: Geometry, Evolution, and Seismic Hazard of the South Coastal Fault System

Tectonics, Volume 45, Issue 7, July 2026.
Abstract In many areas of active faulting, the continuity of normal faults with short or incomplete historical earthquake records and more subdued topographic expressions is not fully understood and consequently the seismic potential of these faults is often underestimated.

Real time identification of microseismic events based on ridge regression improved normative variable analysis

Gong-kuang zidonghua
The identification of microseismic events is the foundation of microseismic monitoring in coal mines. Most existing microseismic monitoring technologies are developed based on the variation law of single physical quantities, which can easily lead to ...

Stress Drop and Seismic Efficiency Distributions Over the Adriatic Indenter (European Southeastern Alps)

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 7, July 2026.
Abstract Seismic source parameters, such as seismic moment, stress drop, and radiated energy, are key to understanding earthquake dynamics and rupture processes. In this study, we apply a non‐parametric Generalized Inversion Technique (GIT) to characterize the source properties of 735 earthquakes (local magnitudes 1.65 ≤ ML ≤ 4.55) recorded between ...

Solution of Microseismic Monitoring Non-Linear Location Equations Based Matlab [PDF]

, 2011
Microseismic will produce when rock mass break. The occurrence of microseismic monitoring has close relationship to the energy release and crack's evolution in the rock mass. Therefore the microseismic monitoring can be used to predict the future rupture

High-resolution microseismic imaging [PDF]

, 2017
We examine the feasibility of high-resolution microseismic imaging of unconventional reservoirs. Given frequencies in typical downhole microseismic data that are almost an order of magnitude higher than in seismic reflection data, a comparable increase ...
