| | Abstract | | At first, in this study, we re-evaluated a source azimuthal dependence for site amplifications of earthquake ground motions (Uebayashi and Horike, 2002) in Hokusetsu Area, Osaka, using seismic data in a north-south survey line performed by Tsuno et al. (2017). To accurately predict strong ground motions in this area, we need to 3-D simulations of earthquake ground motions. Therefore, we performed single-station of microtremor measurements in the Hokusetsu Area, to construct 3-D subsurface velocity structural models. |
