摘要：Modern tsunami events have highlighted the vulnerability of port structures to these high-impact but infrequent occurrences. However, port planning rarely includes adaptation measures to address tsunami hazards. The 2011 Tohoku tsunami presented us with an opportunity to characterise thevulnerability of port industries to tsunami impacts. Here, we provide aspatial assessment and photographic interpretation of freely available datasources. Approximately 5000 port structures were assessed for damage andstored in a database. Using the newly developed damage database, tsunamidamage is quantified statistically for the first time, through the development of damage fragility functions for eight common port industries.In contrast to tsunami damage fragility functions produced for buildingsfrom an existing damage database, our fragility functions showed higherprediction accuracies (up to 75 % accuracy). Pre-tsunami earthquake damage was also assessed in this study and was found to influence overall damage assessment. The damage database and fragility functions for port industries can inform structural improvements and mitigation plans for ports against future events.
