| Abstract | Seismic exploration in the Musa-dake geothermal area was conducted combining the refraction tomography and the MDRS method. The refraction traveltime tomography was applied to delineate near surface velocity structure, which will supplement the reflection seismic profile. Result of the refraction tomography is consistent with the surface geology such as the outcrop of the intrusive rock. The MDRS (Multi-Dip Reflection Surfaces) method was applied to improve the signal to noise ratio. Quality of the seismic section was improved, which helped better understanding of the subsurface structure. |
