Deep subsurface modeling in Kanto plain using pseudo earthquake Horizontal-to-Vertical spectral ratio based on the diffuse field theory.

Abstract We estimated deep subsurface model in Kanto plain using pseudo earthquake horizontal-to-vertical sepctral ratio(pEHVR) based on diffuse field theory. We constructed S-wave velocity structure up to about 50m in depth using small microtremor array data and initial model by coneccting existing deep subsurface structural model. We estimated pEHVRfrom MHVR and estimated deep subsurface model using pEHVR based on the diffuse field theory.
