Groundwater Monitoring with Passive Seismic Interferometry
Passive seismic interferometry takes advantage of natural ambient seismic noise generated by the wind, the storms and the human activities (e.g. cars, trains and hereafter pumps) to recover the slight variations of the seismic wave velocity induced by ...

Weak Signal Enhancement for Passive Seismic Data Reconstruction Based on Deep Learning
In conventional passive seismic exploration, it is often necessary to make a long-period seismic record. On the one hand, the passive seismic records with long period allowed us to screen several good passive seismic records with long period for seismic ...

Near-surface real-time seismic imaging using parsimonious interferometry
Results are presented for real-time seismic imaging of subsurface fluid flow by parsimonious refraction and surface-wave interferometry. Each subsurface velocity image inverted from time-lapse seismic data only requires several minutes of recording time,

4D Physics‐Based Pore Pressure Monitoring Using Passive Image Interferometry
This study introduces a technique for four‐dimensional pore pressure monitoring using passive image interferometry. Surface‐wave velocity changes as a function of frequency are directly linked to depth variations of pore pressure changes through ...

Advanced monitoring of tailings dam performance using seismic noise and stress models
Ambient seismic noise interferometry combined with a quantitative stress model can be used to determine changes in seismic wave velocity and, by extension, other geotechnical parameters which are critical to monitoring tailings dam ...
