Seismic interferometry in the presence of an isolated noise source

Seismica, 2022
Seismic interferometry gives rise to a correlation wavefield that is closely related to the Green’s function under the condition of uniformly distributed noise sources. In the presence of an additional isolated noise source, a second contribution

Permanent, seasonal, and episodic seismic sources around Vatnajökull, Iceland from the analysis of correlograms

Volcanica, 2021
In this study, we locate and characterise the main seismic noise sources in the region of the Vatnajökull icecap (Iceland). Vatnajökull is the largest Icelandic icecap, covering several active volcanoes.

A near-surface seismic scattered wave separation method

Petroleum Exploration and Development, 2014
Considering that near-surface scattered waves could not be suppressed by conventional denoise method, this paper analyzes the characteristics of scattered waves and achieves the near-surface scattered wave separation by the seismic interferometry theory.

Spatiotemporal evaluation of Rayleigh surface wave estimated from roadside dark fiber DAS array and traffic noise

Seismica, 2023
Seismic imaging and monitoring of the near-surface structure are crucial for the sustainable development of urban areas. However, standard seismic surveys based on cabled or autonomous geophone arrays are expensive and hard to adapt to noisy ...

Triple Michelson Interferometer for a Third-Generation Gravitational Wave Detector [PDF]

, 2009
The upcoming European design study `Einstein gravitational-wave Telescope' represents the first step towards a substantial, international effort for the design of a third-generation interferometric gravitational wave detector.

Physics-Based Relationship for Pore Pressure and Vertical Stress Monitoring Using Seismic Velocity Variations

Remote Sensing, 2021
Previous studies examining the relationship between the groundwater table and seismic velocities have been guided by empirical relationships only. Here, we develop a physics-based model relating fluctuations in groundwater table and pore pressure with ...

Combined use of repeated active shots and ambient noise to detect temporal changes in seismic velocity: application to Sakurajima volcano, Japan [PDF]

, 2017
Additional file 1. Comparison of the results of coda-wave interferometry and seismic interferometry on the almost identical wave paths. Gray dots in top two panels are daily dv/v values obtained from seismic interferometry.

Review of Seismic Interferometry

Chigaku Zasshi (Jounal of Geography), 2008
We review seismic interferometry with an example of a numerical simulation. A cross-correlation of two seismic records at different receivers yields a virtual source record that corresponds to the seismic response observed at one receiver due to the source at another receiver location.

Application of Seismic Interferometry by Multidimensional Deconvolution to Earthquake Data Recorded in Malargüe, Argentina

Remote Sensing, 2021
Seismic interferometry (SI) refers to the principle of generating new seismic responses using crosscorrelations of existing wavefield recordings. In this study, we report on the use of a specific interferometric approach, called seismic interferometry by

Interferometric surface-wave isolation and removal [PDF]

, 2007
The removal of surface waves (ground roll) from land seismic data is critical in seismic processing because these waves tend to mask informative body-wave arrivals.
