Advanced monitoring of tailings dam performance using seismic noise and stress models
Communications Earth & Environment, 2022 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 ...

Remote Sensing, 2021 An airgun source in a water reservoir has been developed in the past decade as a green active source that had been proven effective to derive short-term subsurface structural changes. However, seasonal water level fluctuation in the reservoir affects the

Ambient seismic noise tomography of Australian continent [PDF]
Tectonophysics, 2010 Abstract Imaging using information derived from the cross-correlation of the ambient seismic wavefield at different stations has recently become an important tool in seismology. We here present a continent wide study of the Australian crust based on the exploitation of continuous data from extensive portable broad-band deployments across Australia ...

Review of progress in passive seismic reflection exploration
地球与行星物理论评, 2023 Seismic exploration is a key method for the study of underground structures. Active seismic surveys can acquire high signal-to-noise ratio reflection data; however, the operation of active seismic surveys is complicated, and the exploration cost is high.

Seismic attenuation from recordings of ambient noise [PDF]
GEOPHYSICS, 2013 We applied seismic interferometry to data from an ocean-bottom survey offshore Norway and found that ambient seismic noise can be used to constrain subsurface attenuation on a reservoir scale. By crosscorrelating only a few days of recordings by broadband ocean bottom seismometers, we were able to retrieve empirical Green’s functions associated with ...

Reflection images from ambient seismic noise
GEOPHYSICS, 2009 One application of seismic interferometry is to retrieve the impulse response (Green’s function) from crosscorrelation of ambient seismic noise. Various researchers show results for retrieving the surface-wave part of the Green’s function. However, reflection retrieval has proven more challenging. We crosscorrelate ambient seismic noise, recorded along

Spatial and temporal influence of sea level on inland stress based on seismic velocity monitoring
Earth, Planets and Space, 2022 Earth’s crust responds to perturbations from various environmental factors. To evaluate this response, seismic velocity changes offer an indirect diagnostic, especially where velocity can be monitored on an ongoing basis from ambient seismic noise ...

Societal Impact of COVID-19 Crisis on the Ambient Seismic Noise in Metropolitan France
SeismicaThe COVID-19 pandemic led to restrictions on human mobility worldwide. In France, numerous phases of lockdowns and curfews were instituted in an attempt to limit the consequences of this pandemic.
