| Research Abstract |
The research to explore the deep ground structure by using the strong ground motion record was conducted. This research includes the geophysical topics such as the radiative transfer of elastic waves in two-dimensional isotropic scattering media, frequency-dependent attenuation of S-waves and short wavelength heterogeneity of the lithosphere, and the nonstationary ray decomposition in a homogeneous half space. In addition, our research demonstrated that the seismic interferometry of strong ground motion record is very effective to investigate the response function of deep ground structure, and imaged the deep ground structure of the Kanto plain successfully.
