Seismic Interferometry from Correlated Noise Sources [PDF]
Remote Sensing, 2021 It is a well-established principle that cross-correlating seismic observations at different receiver locations can yield estimates of band-limited inter-receiver Green’s functions.

Seismic noise in crystal neutron interferometry. [PDF]
J Appl CrystallogrWe are involved in designing, constructing and operating a split-crystal interferometer that uses X-rays and neutrons simultaneously. Neutron interferometers are sensitive to seismic and acoustic noise due to the low speed, low flux and long detection time of thermal neutrons.

Extrapolation of seismic land streamer data using interferometry [PDF]
Scientific ReportsLand streamer seismic acquisition is increasingly adopted for near-surface geophysical applications due to its operational efficiency and mobility. However, the short source-receiver offsets and weak coupling inherent in land streamer systems limit their

Green’s function representations for seismic interferometry
Geophysics, 2006 Abstract The term seismic interferometry refers to the principle of generating new seismic responses by crosscorrelating seismic observations at different receiver locations. The first version of this principle was derived by Claerbout (1968), who showed that the reflection response of a horizontally layered medium can be synthesized ...

A Comparative Study of Ionospheric Correction on SAR Interferometry—A Case Study of L’Aquila Earthquake [PDF]
Journal of Geodesy and Geoinformation Science, 2022 Synthetic Aperture Radar Interferometry (InSAR) has shown its potential on seismic deformation monitoring since it can achieve the accuracy of centimeter level or even the millimeter level.

Weak Signal Enhancement for Passive Seismic Data Reconstruction Based on Deep Learning
Remote Sensing, 2022 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
Scientific Reports, 2021 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
Geophysical Research Letters, 2023 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
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 ...
