Abstract: A method of characterizing a subsurface of a region includes preparing a plurality of spectra illustrating a spectral density of passive seismic signals obtained in a vicinity of a surface of the region at one or more points of the region where recordings are made of the passive seismic signals. Each spectrum is prepared from an associated signal representative of a movement. The method also includes determining at least one spectral attribute for each frequency appearing in each spectrum so as to obtain a set of spectral attributes associated with the recordings and with the frequencies. The method further includes organizing the set of spectral attributes in a matrix in which each row is associated with one of the recordings. In addition, the method includes applying a principal component analysis method to the matrix in order to determine principal components and deduce therefrom one or more characteristics of the subsurface.
