A METHOD OF OBTAINING INFORMATION ABOUT A SEISMIC SIGNAL FOR USE IN IDENTIFYING ITS SOURCE, WHICH METHOD COMPRISES PRODUCING FROM EACH OF A NUMBER OF PRIOR SEISMIC SIGNALS RESPECTIVELY RECEIVED AT A GIVEN RECEIVING LOCATION FROM A VARIETY OF SOURCES OF LONGITUDINALLY EXTENDING TRANSDUCER ASSEMBLY HAVING A SENSITIVITY DISTRIBUTED ALONG ITS LENGTH AS A FUNCTION OF THE WAVEFORM OF THE CORRESPONDING PRIOR SEISMIC SIGNAL, PRODUCING FROM A SUBSEQUENT SEISMIC SIGNAL ARRIVING AT SAID LOCATION AN ENERGY PATTERN REPRESENTING THE WAVEFORM OF THIS SUBSEQUENT SIGNAL, CAUSING SAID ENERGY PATTERN TO PASS ALONG EACH OF THE TRANSDUCER ASSEMBLIES, DEVELOPING FROM EACH TRANSDUCER ASSEMBLY A SIGNAL REPRESENTING THE EFFECT OF SAID ENERGY PATTERN UPON THAT TRANSDUCER ASSEMBLY, SAID SIGNAL BEING INDICATIVE OF THE CORRELATION BETWEEN THE WAVEFORM OF SAID SUBSEQUENT SEISMIC SIGNAL AND THAT OF THE PRIOR SEISMIC SIGNAL CORRESPONDING TO THE TRANSDUCER ASSEMBLY, AND RECORDING THE CORRELATION SIGNALS OBTAINED FROM EACH TRANSDUCER ASSEMBLY FOR COMPARISON, THEREBY TO FACILITATE IDENTIFICATION OF THE SOURCE OF SAID SUBSEQUENT SEISMIC SIGNAL BY COMPARISON WITH THE SEISMIC SIGNALS RECEIVED AT SAID LOCATION FROM EACH OF SAID VARIETY OF SOURCES.
