We evaluate the probabilistic damage states of an urban coastal city, Seaside, Oregon from future tsunamis generated on the Cascadia Subduction Zone (CSZ). The methodology and the results are separated into two parts: (1) Probabilistic tsunami hazard assessment (Park et al., 2017) and (2) Probabilistic building damage assessment from the tsunamis hazards with a community scale. To analyze future tsunami hazards at Seaside Oregon, we consider various slip distributions on the CSZ full-rupture area. We use the momentum flux fragility curves developed in the Tsunami Methodology Technical Method (2013) and relate the impact to critical facilities.
