THE METHOD OF GENERATING SEISMIC WAVES IN A BORE HOLE IN THE EARTH WHICH COMPRISES THE STEPS OF FILLING A SUBSTANTIAL LENGTH OF SAID BOREHOLE BELOW THE WEATHERINGVELOCITY INTERFACE WITH A MIXTURE OF FUEL GAS AND OXYGEN CAPABLE OF COMBUSTION BY DETONATION, DURING SAID FILLING STEP ADJUSTING THE RELATIVE FLOW RATES OF SAID FUEL GAS AND SAID OXYGEN SO THAT THE VOLUME PERCENT F OF FUEL GAS IN THE MIXTURE WITH OXYGEN IS EQUAL TO K1V-K2, WHERE K1 AND K2 ARE CONSTANTS FOR ANY GIVEN FUEL GAS, AND V IS THE SEISMIC-WAVE-TRANSMISSION VELOCITY OF THE SUBWEATHING FORMATIONS PENETRATED BY SAID BOREHOLE, AND INITIATING DETONATION OF THE COLUMN OF GASES AT THE UPPER END THEREOF.
