Abstract
Coastal cities are exposed to various types of disaster risks, such as tsunamis and storm surges. In particular, a megathrust earthquake has a potential to cause severe damage to cities almost simultaneously in terms of both seismic ground shaking and tsunami damage. However, in the countermeasures against future disasters, seismic and tsunami damage are generally assessed separately, and different source models are assumed for different types of disasters. This study aims to calculate damage probabilities of ground motion and tsunami for buildings in a coastal city under the same earthquake scenarios and to make an intercomparison between these two kinds of hazards.![Creative Commons License](http://i.creativecommons.org/l/by/4.0/88x31.png)
