Stability of Monitoring Weak Changes in Multiply Scattering Media with Ambient Noise Correlation: Laboratory Experiments [PDF]
, 2009 Previous studies have shown that small changes can be monitored in a scattering medium by observing phase shifts in the coda. Passive monitoring of weak changes through ambient noise correlation has already been applied to seismology, acoustics and ...

Seismic interferometry for in-mine exploration
, 2022 Im Zuge des Forschungsprojektes "Seismic Imaging Techniques for Mineral Exploration" wurde die Anwendung von passiver seismischer Interferometrie (PSI) in untertägigen Strecken und dessen Eignung für die Mineralexploration getestet. Zu Validierungszecken wurde PSI mit der 3D-Bohrlochradartechnologie und einer aktiven seismischen Messung verglichen. Die

Autocorrelation Seismic Imaging of Northern Taiwan Using Ambient Noise Data
Journal of Geophysical Research: Solid Earth, Volume 131, Issue 5, May 2026.Abstract Over the past few million years, northern Taiwan records a tectonic history of subduction to arc–continent collision followed by post‐collisional collapse. This evolution motivates constraints on crustal structure, including crustal layering and thickness.

Retrieving time-dependent Green's functions in optics with low-coherence interferometry [PDF]
, 2015 We report on the passive measurement of time-dependent Green's functions in the optical frequency domain with low-coherence interferometry. Inspired by previous studies in acoustics and seismology, we show how the correlations of a broadband and ...

Geophysical Prospecting, Volume 74, Issue 4, May 2026.ABSTRACT Microseismic monitoring of offshore CO2$\rm CO_2$ storage projects is likely to include some deployment of offshore sensors. To improve the value proposition of this monitoring infrastructure, it is important to consider what other information can be gained about the CO2$\rm CO_2$ storage complex and the surrounding region.

Frontiers in Earth Science, 2019 On active volcanoes, ambient noise-based seismic interferometry can be a very useful monitoring tool as it allows to detect very slight variations in seismic velocity associated with magma transported toward the surface.

Phase noise due to vibrations in Mach-Zehnder atom interferometers
, 2006 Atom interferometers are very sensitive to accelerations and rotations. This property, which has some very interesting applications, induces a deleterious phase noise due to the seismic noise of the laboratory and this phase noise is sufficiently large ...

Testing the universality of free fall with rubidium and ytterbium in a very large baseline atom interferometer [PDF]
, 2015 We propose a very long baseline atom interferometer test of Einstein's equivalence principle (EEP) with ytterbium and rubidium extending over 10m of free fall.

Layered Seismic Anisotropy and Tectonics of the Anatolian Plate
Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.Abstract Anatolian tectonics are associated with slab retreat in the west and gravitational potential energy and continental collision in the east, leading to westward motion of Anatolia relative to Eurasia, partially accommodated on the North and East Anatolian transform faults.
