Method for correcting a seismic signal s(t) supplied by a vibration sensor (100) in response to at least one emission signal F(t) produced by at least one seismic vibration generator (200), the said emission signal F(t) having phase and amplitude differences with a reference emission signal F(t). According to the invention, the said correction method consists in determining, as a function of the frequency f, the phase difference DELTA 0(f) and the amplitude ratio A(f) between the emission signal F(t) and the reference emission signal F(t), and in applying a filter (304) to the seismic signal s(t) of the vibration sensor (100), the response of which filter is defined in phase and in amplitude respectively by - DELTA 0(f) and 1/A(f). Application to terrestrial seismology. <IMAGE>
