Sampled Building Dataset for Building Vulnerability Classifiction and Tsunami Fragility Analysis

This dataset contains sampled buildings used to develop multi-event tsunami fragility curves. It includes records from three major tsunami events: the 2011 Great East Japan Earthquake and Tsunami (Natori and Rikuzentakata, Japan), the 2018 Sulawesi Tsunami (Palu, Indonesia), and the 2018 Sunda Strait Tsunami (Banten and Lampung, Indonesia). For each building, hazard intensity (inundation depth), structural attributes (construction material and number of storeys), surrounding characteristics (coastal vegetation and coastal protection), and the computed vulnerability index (VI) with recorded damage states are provided. Data are organised into three sheets corresponding to the vulnerability classes: V1 (less vulnerable), V2 (vulnerable), and V3 (highly vulnerable).
