Abstract:
This paper discusses the applicability of tsunami fragility curves to estimate the damage of buildings due to tsunami. Tsunami fragility curves have been developed empirically out of the damage data obtained from large scale tsunami disasters (Koshimura et al., 2009; Mas et al., 2012a; Suppasri et al., 2011, 2013). Fragility curves can provide an overall idea of the impact of a tsunami event, however, for disaster mitigation purposes a desired application for these curves is the assessment of possible future damage due to tsunami. Thus, this report aims on evaluating the applicability of tsunami fragility curves for building damage estimation. Our hypothesis is that a building damage estimation due to tsunami performed with fragility curves developed in the same location and urban characteristics (i.e. building type, layout, topography, etc.) should provide a high accuracy. This is expected since the data (event and buildings) used to develop the fragility curve contains the sample use for the evaluation.
