Passive seismic interferometry for reflection imaging & monitoring
2017Passive seismics is the set of applications that endeavours the exploration of theEarth’s mechanical properties using naturally occurring sources in the subsurface.Conventional imaging of the subsurface is achieved with the aid of reflectionsurveys of body waves from the surface.

I propose a direct migration method for passive seismic data based on a reverse time migration combined with a concept of the seismic interferometry. The subsurface image is obtained by three steps in this method which is recognized as the seismic interferometry in the image domain; the first is model-based wavefield extrapolation of time-windowed ...

Passive Image Interferometry (PII) is a seismological method employing ambient seismic noise to monitor the temporal evolution of mean shear wave velocity within the Earth. First, the elastic Green's tensor between two seismometers is computed from the cross correlation of seismic noise recorded during a certain period.

Monitoring a CO2-Storage site with Passive Image Interferometry
2013In seismology, Passive Image Interferometry (PII), based on ambient seismic noise, can be used to detect small temporal changes in the propagation of the seismic wavefield. As these changes can be related to changes of elastic properties in the propagation medium, PII can be used to observe dynamic processes in the earth’s crust.
