On the Retrievability of Seismic Waves From High-Speed-Train-Induced Vibrations Using Seismic Interferometry

IEEE Geoscience and Remote Sensing Letters, 2022
High-speed train (HST) generates strong and repeatable vibrations that could be used for subsurface imaging and monitoring. Compared with other ambient noise, HST vibrations are generated by a moving source and have striking characteristics as a ...

Elimination of free-surface-related multiples by combining Marchenko scheme and seismic interferometry

Geophysics, 2022
The removal of free-surface-related multiples plays an important role in seismic data processing. We propose a novel scheme for predicting free-surface-related multiples by combining the revised Marchenko equations with free surface effects and ...

Inversion of vehicle-induced signals based on seismic interferometry and recurrent neural networks

, 2021
Vehicle-induced vibrations provide useful signals for passive seismic exploration. Such signals are repeatable and environmentally friendly; hence, they can provide an economical way to analyze subsurface structures.

Seismic interferometry by cross‐correlation or deconvolution?

SEG Technical Program Expanded Abstracts 2008, 2008
We discuss Rodney Calvert's work on the Virtual Source method in the context of seismic interferometry. Moreover, we present a systematic analysis of seismic interferometry by cross-correlation versus multi-dimensional deconvolution and we discuss applications of both approaches.

Seismic interferometry—turning noise into signal

The Leading Edge, 2006
Turning noise into useful data—every geophysicist's dream? And now it seems possible. The field of seismic interferometry has at its foundation a shift in the way we think about the parts of the signal that are currently filtered out of most analyses—complicated seismic codas (the multiply scattered parts of seismic waveforms) and background noise ...

Laser interferometry based seismic sensor

SPIE Proceedings, 2003
Laser interferometry is one of the most sensitive and versatile techniques for small relative displacements measurement. For these reasons it is used or it is being introduced in many different fields of research. One of its possible applications is seismic activity monitoring, obtained by fixing the mirrors of an interferometer to the ground. In order

Effect of Intrinsic Losses on Seismic Interferometry

70th EAGE Conference and Exhibition incorporating SPE EUROPEC 2008, 2008
Seismic interferometry (SI) is the process of generating new seismic traces from the cross-correlation of existing traces. One of the starting assumptions for deriving the SI representation equations is that of a lossless medium. In practice, this condition is not always met.

Applications of seismic interferometry to seismic field data

The Journal of the Acoustical Society of America, 2007
In seismic interferometry one extracts the Green’s function of a system from fluctuations in the system. This makes it possible to retrieve the waves that propagate between receivers, as if one of the receivers acts as a source. Examples are presented of this principle to field data.

Seismic Interferometry in Near-Surface Seismics - An Experiment

Near Surface 2006 - 12th EAGE European Meeting of Environmental and Engineering Geophysics, 2006
Seismic interferometry (SI) is the process of generating new seismic records from the cross-correlation of existing records. The interest to SI is growing, but mainly in hydrocarbon exploration and global seismology. The application of SI to shallow seismics could help to extract more information form the data and at the same time save efforts and time

Passive Seismic Interferometry as a Tool for Seismic Imaging from Mine Galleries

83rd EAGE Annual Conference & Exhibition, 2022
To test passive seismic interferometry (PSI) in underground mining environments, we carried out an active-source seismic and continuous noise measurement in a mine gallery of a former radioactive waste repository - the Asse II salt mine (Lower Saxony, Germany).
