Single‐station monitoring of volcanoes using seismic ambient noise [PDF]

open access: yesGeophysical Research Letters, 2016
AbstractSeismic ambient noise cross correlation is increasingly used to monitor volcanic activity. However, this method is usually limited to volcanoes equipped with large and dense networks of broadband stations. The single‐station approach may provide a powerful and reliable alternative to the classical “cross‐station” approach when measuring ...

Understanding the amplitudes of noise correlation measurements [PDF]

open access: yes, 2011
Cross correlation of ambient seismic noise is known to result in time series from which station-station travel-time measurements can be made. Part of the reason that these cross-correlation travel-time measurements are reliable is that there exists a ...

Advanced monitoring of tailings dam performance using seismic noise and stress models

open access: yesCommunications 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 ...

Impacts of Reservoir Water Level Fluctuation on Measuring Seasonal Seismic Travel Time Changes in the Binchuan Basin, Yunnan, China

open access: yesRemote 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

Stability of Monitoring Weak Changes in Multiply Scattering Media with Ambient Noise Correlation: Laboratory Experiments [PDF]

open access: yes, 2009
Previous studies have shown that small changes can be monitored in a scattering medium by observing phase shifts in the coda. Passive monitoring of weak changes through ambient noise correlation has already been applied to seismology, acoustics and ...

Distributed and Communication-Efficient Spatial Auto-Correlation Subsurface Imaging in Sensor Networks

open access: yesSensors, 2019
A wireless seismic network can be effectively used as a tool for subsurface monitoring and imaging. By recording and analyzing ambient noise, a seismic network can image underground infrastructures and provide velocity variation information of the ...

Review of progress in passive seismic reflection exploration

open access: yes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.
