A METHOD OF REVERSIBLY OBTAINING A DIGITAL SEISMIC SIGNAL COMPRISING THE STEPS OF: PRODUCING A SEISMIC DISTURBANCE, RECEIVING AT SPACED POINTS IN THE VICINITY OF SAID SEISMIC DISTURBANCE A SERIES OF SEISMIC SIGNALS GENERATED BY SAID SEISMIC DISTURBANCE, SEQUENTIALLY SAMPLING THE AMPLITUDES OF SAID SEISMIC SIGNALS, CONVERTING THE SEQUENTIALLY SAMPLED AMPLITUDES INTO DIGITAL DATA, APPLYING SAID DATA TO A RECORDING MEDIUM, RECONVERTING SAID RECORDED DATA INTO ANALOG SEISMIC SIGNALS, VISIBLY DISPLAYING SAID ANALOG SEISMIC SIGNALS, AND RETAINING DURING SAID APPLYING OPERATON A CONTINUOUS DIGITAL ELAPSED TIME INDEX REFERENCED TO THE OCCURRENCE TIME OF SAID SEISMIC DISTURBANCE.
