A number of buildings were damaged by the 2011 Great East Japan tsunami inthe Tohoku area. The research objective is to determine the significant predictor variablesof the level of building damage. This paper used detailed data on damaged buildings inKesennuma City, Japan, collected by the Ministry of Land, Infrastructure, Transport andTourism (MLIT). The tested explanatory parameters included the inundation depth,number of floors, volume of the building, debris flow, structural material, and function ofthe building. Through multinomial logistic regression, the results found that the number offloors was significantly associated with the damage level; the inundation depth, structuralmaterial (reinforced concrete and masonry), and function of the building (commercialfacility, transportation/storage facility, and public facility) were partially associated with thedamage level. This study can contribute to academic research by assessing the contributionof different variables to observed damage data by applying statistical analysis, as well as thepractical contribution of providing an examination of the predominant factors drivingtsunami damage to buildings.
