Passive image interferometry for monitoring crustal changes with ambient seismic noise
Comptes Rendus - Geoscience, 2011 Abstract The technique to retrieve Green’s functions by cross-correlation of seismic noise that is now often referred to as seismic interferometry opened the way to a completely new type of seismological observation – the continuous monitoring of changes in the subsurface medium.

Geophysical Research Letters, 2006 We propose passive image interferometry as a technique for seismology that allows to continuously monitor small temporal changes of seismic velocities in the subsurface. The technique is independent of sources in the classical sense and requires just one or two permanent seismic stations. We retrieve the Green's functions that we use for interferometry

Comparison of four techniques for estimating temporal change of seismic velocity with passive image interferometry [PDF]
Earthquake Science, 2010 Passive image interferometry (PII) is becoming a powerful tool for detecting the temporal variations in the Earth’s structure, which applies coda wave interferometry to the waveforms from the cross-correlation of seismic ambient noise. There are four techniques for estimating temporal change of seismic velocity with PII: moving-window cross-correlation

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).

Comprehensive observation and modeling of earthquake and temperature‐related seismic velocity changes in northern Chile with passive image interferometry [PDF]
Journal of Geophysical Research: Solid Earth, 2014 AbstractWe report on earthquake and temperature‐related velocity changes in high‐frequency autocorrelations of ambient noise data from seismic stations of the Integrated Plate Boundary Observatory Chile project in northern Chile. Daily autocorrelation functions are analyzed over a period of 5 years with passive image interferometry.
