The critical angle in seismic interferometry
SEG Technical Program Expanded Abstracts 2008, 2008Limitations with respect to the characteristics and distribution of sources are inherent to any field seismic experiment, but in seismic interferometry these lead to spurious waves. Instead of trying to eliminate, filter or otherwise suppress spurious waves, crosscorrelation of receivers in a refraction experiment indicate we can take advantage of ...

A Comparison of Strategies for Seismic Interferometry
Surveys in Geophysics, 2009The extraction of the response from field fluctuations excited by random sources has received considerable attention in a variety of different fields. We present three methods for the extraction of the systems response that are based on cross-correlation, deconvolution, and the solution of an integral equation, respectively.

Introduction to the supplement on seismic interferometry
Geophysics, 2006Abstract In 1968, J. F. Claerbout derived a remarkable relation between the transmission and reflection responses of a horizontally layered medium, bounded by a free surface (Claerbout, 1968). He showed that autocorrelation of the transmission response is equal to the reflection response plus its time-reversed version (plus an impulse

Global Scale Seismic Interferometry
68th EAGE Conference and Exhibition - Workshop Package, 2006Seismic reflection imaging has shown its virtues on exploration scale, but has little been applied on a global scale due to the sparse source distribution; the earthquake hypocenters are mainly along the active lithospheric plate boundaries. This problem can be approached with Seismic Interferometry (SI).

Groundwater Level Monitoring Tests with Seismic Interferometry
NSG2020 26th European Meeting of Environmental and Engineering Geophysics, 2020Summary The objective of this work is to evaluate whether the seismic passive interferometry technique can be used to monitor undeground water variations in both unconfined and confined aquifers that present different hydrogeological characteristics. We collected ambient vibrations in two different water catchment fields where the water level has been ...

Seismic interferometry is a powerful tool to monitor the seismic velocity change associated with volcanic eruptions. For the monitoring, changes in seismic velocity with environmental origins (such as precipitation) are problematic. In order to model the

Seismic interferometry is an exciting field in geophysics utilising multiple scattering events to provide unprecedented views of the Earth's subsurface. This is a comprehensive book describing the theory and practice of seismic interferometry with an emphasis on applications in exploration seismology.

Near-surface site investigation by seismic interferometry using urban traffic noise in Singapore
Geophysics, 2019We have evaluated a field test in the city of Singapore to assess the feasibility of the passive seismic survey for bedrock depth determination and to further investigate the optimal acquisition parameters.

Locate Microseismicity by Seismic Interferometry
Proceedings, 2009We present a new seismic interferometry method to locate microseismicity by crosscorrelating the direct P- and S-waves from repeating sources, e.g., hydro-fracture. Typically microseismic data by surface array are below signal-to-noise ratio for a migration-type approach, and barely pickable for a traveltime-base approach.
