Beyond Correlations: Deep Learning for Seismic Interferometry
IEEE Transactions on Neural Networks and Learning Systems, 2023Passive seismic interferometry is a vastly generalized blind deconvolution question, where different paths through the Earth correspond to different channels called Green's functions; the sources are completely incoherent and not shared by the channels, and the question is to estimate paths (channels) that are not present in the dataset.

Extracting seismic core phases with array interferometry [PDF]
Geophysical Research Letters, 2013 Seismic body waves that sample Earth's core are indispensable for studying the most remote regions of the planet. Traditional core phase studies rely on well-defined earthquake signals, which are spatially and temporally limited.

Seismic Interferometry in Near-Surface Seismics - An Experiment
Near Surface 2006 - 12th EAGE European Meeting of Environmental and Engineering Geophysics, 2006Seismic 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, 2022To 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).

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

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.
