| | Abstract | | The multi-component seismic data give us much information for the subsurface imaging and the analysis of rock properties, and the use of the P-S converted waves is now practical to obtain subsurface image constructed by shear waves instead of the S-S reflections. In these years, the technical innovation on MEMS-based accelerometers achieved efficient acquisitions of the multi-component data. In addition, the seismic exploration aiming the deep earth structures has been usually conducted. On these facts, the use of the P-S converted waves will increase in the deep reflection survey with the multi-component data. In this study, we applied P-S imaging to the three-component data acquired with the MEMS-based accelerometers on a 20km-long survey line in the Kitakami lowland, northeast Japan. The obtained P-S section clearly shows the structure from the sedimentary layers to the basement and the form of west dipping listric faults. The result from P-S processing is compatible with that from the conventional P-P processing. Our result represents the usefulness of the P-S converted waves in the deep seismic profiling. |
