Okirihata Bridge, Kuwaduru Bridge, Oginosaka Bridge, Tawarayama Bridge, Aso-Choyo Bridge, Minami-Aso Bridge and Aso Bridge, which are located near the epicenter of the 2016 Kumamoto Earthquake were damaged due to the strong motion. In order to analyze the damage mechanism, it is very important to evaluate the strong motion at the bridge sites of interest with high accuracy. In this study, aftershock observations were conducted at the bridge sites of interest in order to evaluate the empirical site effects. Seismic waveforms at the bridge sites of interest during the 2016 main shock were then estimated based on the site effects and the characterized source model. The estimated ground motions will be useful in the detailed study of the damage mechanism.
