An attempt for the pre-stack depth migration using integrated OBS and MCS data

Abstract The pre-stack depth migration (PSDM) is one of the effective methods to clarify the detailed crustal structure. By the PSDM for the multi-channel seismic reflection (MCS) data, the shallow part of the crust could be imaged well. On the other hand, the deep part of the crust could be imaged by the PSDM for ocean bottom seismographs (OBS) wide-angle data. Moreover, the pseudo seismic data (SI data) applying by seismic interferometry for OBS wide-angle data could be imaged the area which could not be imaged by the PSDM for MCS data and for OBS wide-angle data. In this study, we attempt the PSDM for integrated OBS and SI data, and integrated these data and MCS data. In this result, we could image the crustal structure from the shallow part to the Moho, simultaneously.
