Comparing ambient-noise-based seismic velocity variations with dynamic and static strain changes associated with major earthquake rupture at Parkfield [PDF]

open access: yes, 2023
Stress perturbations across a fault zone can change seismic wave velocity in the adjacent area, with implications for rock properties and fault mechanics.

A novel horizontal to vertical spectral ratio approach in a wired structural health monitoring system [PDF]

open access: yesJournal of Sensors and Sensor Systems, 2014
This work studies the effect ambient seismic noise can have on building constructions, in comparison with the traditional study of strong seismic motion in buildings, for the purpose of structural health monitoring. Traditionally, engineers have observed

Dead Sea Basin Imaged by Ambient Seismic Noise Tomography [PDF]

open access: yesPure and Applied Geophysics, 2011
In the framework of the Dead Sea Integrated Research project (DESIRE), 59 seismological stations were deployed in the region of the Dead Sea Basin. Twenty of these stations recorded data of sufficiently high quality between May and September 2007 to be used for ambient seismic noise analysis.

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

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 ...

Ambient seismic noise tomography of Australian continent [PDF]

open access: yesTectonophysics, 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 ...

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 ...

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.
