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 ...

Global-scale seismic interferometry
2018Applying seismic reflection imaging on a global scale is hard due to the (locally) sparse source distribution. We approach this problem with seismic interferometry (SI). In this paper, we derive an expression for global-scale SI and test it on a simplified 2D acoustic lossless Earth model. When we use responses from sources placed all around the model,

Seismic time-lapse interferometry across scales
2019Abstract The ambient seismic wavefield or noise is the ubiquitous low-amplitude background ground motion that is recorded by all seismic sensors. The recorded signals are characterized by a seemingly random train of continuous waveforms. However, the cross-correlation of seismic ambient wavefield records from different receiver locations yields ...
