Summary Design earthquake motion for highway bridges is studied taking account of coupling of source regions and long duration ground motions observed during the 2011 Tohoku earthquake. Tsunami forces acted on highway structures triggered by the earthquake are reproduced by numerical simulations of tsunami propagation and run-up using detailed terrain models.
