Abstract
In subduction-zone earthquakes, which cause a tsunami, it is considered that the influence of aftershocks may act on a breakwater even when wave-overtopping is taking place. However, it is unclear what effect the superposition of earthquake and tsunami will have on breakwaters. In this study, a large hydroflume capable of reproducing the superposition phenomenon of earthquake and tsunami was used. The study revealed the influence due to frequency difference and the difference depending on the presence or absence of deformation of the mound.
