Abstract
A determination methodology of scenario tsunamis which are based on results of probabilistic tsunami hazard assessment and have specific annual frequencies of exceedance is proposed. By carrying out the probabilistic tsunami hazard deaggregation, tsunami conditions, which should be considered to determine the scenario tsunamis for fragility assessment in the tsunami PRA are identified. An annual frequency of exceedance of tsunami height in front of a seawall on a site by using the scenario tsunamis are evaluated and compared with that evaluated by the tsunami hazard analysis. The comparison shows good agreement, and thus the applicability of the proposed methodology is confirmed.
