| | Abstract | | The estimation of oceanic crust structure is required to reveal the development history of Japanese island arcs. Refraction or reflection wave exploration is one of the methods for deep oceanic crust investigation, but these methods use only compressional wave or the depth component of seismometer. Hence, there is a possibility to use shear wave or horizontal component of seismograms to estimate more precisely the thickness of oceanic crust. Receiver function is a function to estimate the interface of velocity change using shear wave from earthquake without artificial sources. This study tries to apply receiver function analysis to the investigation using refraction wave not from earthquake but artificial sources on the ground or sea surface. |
