Abstract
A method for locating and identifying site anomalies. According to the method, a given seismic block of seismic traces located by their space coordinates is used. The seismic block is demarcated in at least one time interval between a higher level and a lower level. A time-model of one anomaly is selected. The model is correlated with each of the traces within the time interval. For each trace, the maximum correlation (.GAMMA..sub.M)and the corresponding time (t.sub.i) of the said maximum correlation are calculated. A maxima correlation chart equal to the spatial dimensions of the seismic block and a chart of the times corresponding to the correlation maxima are drawn, in which the time chart is of the same dimensions and located in the same system of coordinates (x, y) as the maxima correlation chart.
