Abstract

This invention features a method for locating and identifying site anomalies. It is characterized by the steps of:
- Using a given seismic block (1) consisting of seismic traces located by their space coordinates;
- Demarcating in the said seismic block at least one time interval between a higher level (2) and a lower level (3);
- Selecting a time-model (5) of one anomaly;
- Correlating the said model (5) with each of the said traces (4) within the said time interval;
- Calculating for each trace the maximum correlation (.GAMMA.M) and the corresponding time (t i) of the said maximum correlation;
- Drawing a maxima correlation chart (7) equal to the spatial dimensions of the seismic block (1) and a chart (8) of the said times corresponding to the correlation maxima;
the said time charg being of the same dimensions and located in the same system of coordinates (x, y) as the said maxima correlation chart.
