摘要
For each receiver of an array of three or more receivers monitoring a seismic event, reverse time propagation of a recorded wavefield is performed for the respective receiver to derive an extrapolated wavefield for the respective receiver. An imaging condition is applied as a crosscorrelation of the extrapolated wavefields for the three or more receivers to derive an image of the seismic event. A source of the seismic event is identified based on the image.
