Abstract

 Serious failure of masonry retaining wall was occurred in Kumamoto Castle due to the 2016 Kumamoto earthquake sequence. Therefore, to clarify the failure mechanism, it is necessary to estimate strong motions in the castle with sufficient accuracy, taking into account local site effects. In this study, seismic waveform in the castle was estimated based on the site-effect substitution method. The site effects in the castle were evaluated based on microtremor measurement with high dense spatial location. Difference of the site effects between the castle area and the present observation stations was also indicated.
