Short summary
Post-event field survey data from two tsunami events, the 2011 Tōhoku tsunami, Japan, and the 2015 Illapel tsunami, Chile, are used in this study to develop fragility functions for roads and bridges. This study demonstrates the effectiveness of supplementing post-event field surveys with remotely sensed data. The resulting fragility functions address a substantial research gap in tsunami impacts on infrastructure and include a range of subtleties in asset and hazard characteristics.
