Claim One:
1. A method for suppressing noise trains in seismic data representative of detected multiple seismic events and noise by a plurality of seismic detection means so as to provide enhanced seismic data, comprising (a) deriving elementary seismic traces data for each seismic detection means from the seismic data representative of detected seismic events by said seismic detection means, (b) deriving elementary seismograms from the elementary siesmic trace, (c) combining at least two elementary seismograms in a manner to derive noise seismograms, the number of noise seismograms being at least equal to the number of elementary seismograms to be combined to form a final seismogram, (d) determining the probability distribution of noise for each trace of the noise seismogram, determining the probability distribution of noise in said traces of the elementary seismograms from the probability distributions of noise in the traces of the noise seismograms; and (f) providing the enhanced seismic data from the seismic data in accordance with the probability distribution of step (e).
