Analysis of surface transient charge and the interdependent response of microseismic signal during the deformation of coal

矿业科学学报, 2020
The stress changes, transient charges and microseismic signals of briquette samples during uniaxial compression failure were monitored and analyzed by using the self-made experimental system for measuring transient charges and microseismic signals on the

Joint location of microseismic events in the presence of velocity uncertainty [PDF]

, 2013
The locations of seismic events are used to infer reservoir properties and to guide future production activity, as well as to determine and understand the stress field.

On the Construction of Moho Reflected Shear Wave Phases From Ambient Noise

Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract Shear waves reflected from the Moho (SmS) are frequently identified in ambient noise cross‐correlation functions. Despite their consistent appearance across various arrays and studies, the physical origin and generation mechanisms of these SmS phases remain poorly understood.

Noise Suppression Method of Microseismic Signal Based on Complementary Ensemble Empirical Mode Decomposition and Wavelet Packet Threshold

IEEE Access, 2019
Aiming at the situation that complementary ensemble empirical mode decomposition (CEEMD) noise suppression method may produce redundant noise and wavelet transform easily loses high-frequency detail information, considering wavelet packet transform can ...

Adaptive filtering of microseismic data for monitoring a water-conducting fractured zone in a mine

Scientific Reports, 2022
Water-conducting fractured zones in a rock mass can cause problems in mining. Attempts have been made to monitor their development using microseismic signals.

Cross-correlation imaging of ambient noise sources [PDF]

, 2015
We develop and apply a novel technique to image ambient seismic noise sources. It is based on measurements of cross-correlation asymmetry defined as the logarithmic energy ratio of the causal and anticausal branches of the cross-correlation function.

The Role of Normal Stress and Shear Stress Heterogeneity in the Inferred Depth‐Independence of Stress Drop

Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract Earthquake stress drops are inferred to be independent of source depth, contradicting linear scaling predictions for earthquakes as frictional stick‐slip instabilities that assume increasing fault normal stress due to overburden. Here, we examine the scaling between averaged stress drops and increasing normal stress for simulated earthquake ...

Characterization of the seismic environment at the Sanford Underground Laboratory, South Dakota [PDF]

, 2010
An array of seismometers is being developed at the Sanford Underground Laboratory, the former Homestake mine, in South Dakota to study the properties of underground seismic fields and Newtonian noise, and to investigate the possible advantages of ...

Cycled Fluid Injection Limits Maximum Earthquake Size by Controlling the Cadence of Seismic Moment Release

Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract Controlling fluid injection is widely considered a key to limiting the size of injection‐induced seismicity, yet whether and how it limits earthquake size remains debated. We perform injection‐reactivation experiments on critically stressed faults to test how different injection strategies shape slip and seismic moment release.

Salt Precipitation‐Driven Rock Failure Mode Transition During Geological CO2 Sequestration

Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract Salt precipitation has emerged as a critical factor affecting injectivity, reservoir stability, and the potential to trigger near‐wellbore microseismic activity during geological CO2 sequestration. While previous studies have primarily focused on the brine acidification induced by CO2 injection, triggering geochemical reactions in carbonate ...
