Rock Burst Mechanism under Coupling Action of Working Face Square and Regional Tectonic Stress

Shock and Vibration, 2021
With the development of faults in many coalfields, many large faults will form a relatively independent area, forming regional tectonic stress concentration.

The fast response of volcano-seismic activity to intense precipitation: Triggering of primary volcanic activity by rainfall at Soufrière Hills Volcano, Montserrat [PDF]

, 2009
One-minute resolution time series of rainfall and seismic data from the Soufriere Hills Volcano, Montserrat are analysed to explore the mechanism of external forcing of volcanic eruptions by rainfall over three years of activity.

Automated hypocenter determination of tectonic tremors in the Nankai subduction zone using convolutional neural networks combined with semblance analysis

Earth, Planets and Space
Recent advances in deep learning have enhanced our ability to analyze seismic waveforms. Here, we developed and evaluated a convolutional neural network (CNN) model to classify tectonic tremors, earthquakes, and noise in seismic waveform data recorded by

An optimizing microseismic method for rock burst early warning based on mining production process

Deep Underground Science and Engineering, EarlyView.
A classification early warning method of rock burst based on hourly microseismic data is proposed, which can be combined with the on‐site production process to provide more timely warning. Abstract Microseismic (MS) events have been reported in nearly every coal mining country, which could well lead to rock burst in underground coal mines.

Detection of small crustal deformation caused by slow slip events in southwest Japan using GNSS and tremor data

Earth, Planets and Space, 2019
We stacked daily Global Navigation Satellite System (GNSS) displacement increments in southwest Japan to detect the cumulative crustal deformation accompanying non-volcanic low-frequency tremors from April 1, 2004 to December 31, 2009, which are ...

Advances in vital‐sign prediction and early‐warning models for underground coal mine workers integrating environmental factors

Deep Underground Science and Engineering, EarlyView.
This review synthesizes advances in predicting miners' vital signs by integrating environmental monitoring (dust, temperature, and gas) with physiological data. It highlights multi‐source data fusion techniques and early‐warning models for enhanced occupational safety in underground coal mines.

Long-term slow slip events with and without tremor activation in the Bungo Channel and Hyuganada, southwest Japan

Earth, Planets and Space, 2023
Slow slip events (SSEs) lasting for approximately 1 year occur every 6–8 years around the Bungo Channel in the southwest Japan subduction zone. The slip time evolution of the latest Bungo Channel SSE that occurred in 2018–2019 has been studied; however ...

Probing the nature of low-frequency earthquakes through the deconvolution of tectonic tremor

Journal of Geophysical Research: Solid Earth, 2023
Currently there are two end-member views of low-frequency earthquakes (LFEs). One is that they result from stick-slip behavior of Mxed brittle patches that are mechanically distinct from the surrounding, creeping, fault. The other is that they represent the high-frequency limit of stochastic accelerations and decelerations of slip on the fault, with ...
