During the past decades, significant progress has been made in the development of induced
seismicity monitoring for related human activities. Hydraulic fracturing and induced …

Wave propagation and attenuation in subsurface rock masses could be highly affected by
rock joints filled with fluids. However, the understanding of acoustic behaviours across fluid …

The extraction of body waves from passive seismic recordings has great potential for
monitoring and imaging applications. The low environmental impact, low cost, and high …

It has been a challenge to accurately characterize fracture zones created by hydraulic
fracturing from microseismic event locations. This is because generally detected events are …

Microseismic signal is typically weak compared with the strong background noise. In order to
effectively detect the weak signal in microseismic data, we propose a mathematical …

Detection of seismic events at or below the noise level is enabled by the use of dense arrays
of receivers and corresponding advances in data analysis methods. It is not only important to …

Ambient noise tomography (ANT) has become a routine method to image shear‐wave
velocity variations at different scales. However, ANT can only resolve smooth velocity …

Coalbed methane (CBM), generated and stored in coalbeds, is a form of greenhouse gas.
The emission of CBM in the process of mining is detrimental to the Earth's environment …

Though well known for layer boundaries, the use of amplitude-versus-offset (AVO) variations
for non-welded boundaries like fractures is not yet investigated. Depending on the seismic …
