Résumé:

The time reversal operation in seismic source estimation is considered. We show that the time reversal operation, equally the adjoint operation, for seismic source imaging gives an approximate solution to more conventional seismic source inverse problem through the 'happy approximation' underlined by Claerbout. Practical applications of such methods in a long-period range to monitor earth's activities in realtime are also discussed.
