Near-surface structure of the Sodankylä area in Finland, obtained by passive seismic interferometry [PDF]

Solid Earth, 2021
Controlled-source seismic exploration surveys are not always possible in nature-protected areas. As an alternative, the application of passive seismic techniques in such areas can be proposed.

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 ...

An imaging interferometry capability for the EISCAT Svalbard Radar [PDF]

Annales Geophysicae, 2005
Interferometric imaging (aperture synthesis imaging) is a technique used by radio astronomers to achieve angular resolution that far surpasses what is possible with a single large aperture.

Passive seismic imaging of the Lower Palaeozoic in the Sudret area of Gotland, Sweden [PDF]

Solid Earth
Passive seismic data were acquired together with active seismic data along a 2.8 km long profile in the Sudret area of Gotland, Sweden, as part of a feasibility study for storage of CO2 below the Baltic Sea. Seismic interferometry using cross-correlation

The use of passive seismic interferometry for the monitoring of subsurface fluids – from shallow groundwater to native or storage gas reservoirs [PDF]

E3S Web of Conferences
Passive (ambient noise) seismic interferometry provides multiple ways to gather information about the subsurface seismic properties using recordings of the seismic ambient noise signal.

Impact of source and receiver distributions on imaging of dipping reflectors with passive reflection seismic interferometry

Geophysical Journal International, 2022
SUMMARY Passive reflection seismic interferometry (PRSI) facilitates imaging the subsurface structure using passive sources but according to the general theory, the target needs to be illuminated equally from all directions to obtain a kinematically correct result.
