1. A computerized method of characterizing a geological region of interest comprising: providing a data set comprising data obtained by seismic imaging of the region of interest during an observation period, said data set comprising, for each bin of the region of interest, data related to an emission signal, a reception signal, and a signal geometry, determining an intrinsic geological variability of a bin of the region of interest from the comparison of reception signals for neighbour bins as a function of a difference in signal geometry for said neighbour bins.
