Presentation and interpretation of seismic data

(57) Summary book invention relates to the presentation of three-dimensional earthquake data (90), and an interpretation. Especially the present invention relates to the method and equipment which identify the underground domain of capacity measurement in which the boundary was established by the surface which has a value with the specific constant earthquake characteristic. In the one case of the operation, the three-dimensional earthquake data (90) to underground volume (60) is supplied as an input to the computer program (94) for performing "アイソ surface" processing of data (90). This produces as a result the video display (Fig. 5) of the three-dimensional subvolume (60, 70) defined by the surface (62, 64) that the earthquake characteristic that the boundary is specific has a steady value.
