Description

<p> In order to evaluate the relationship between building damage and tsunami inundation depth due to the 2024 Noto Peninsula earthquake and tsunami, we surveyed Kasugano, Ukai, Iida and Jike of Suzu city in Ishikawa prefecture, Japan and revealed the distribution of building damage and inundation depth. After that, we integrated these data on GIS software and analyzed the qualitative and quantitative relationship of them. Major findings of this manuscript are that; (1) the spatial distribution of building damage was clarified for 1,557 buildings in the tsunami inundation area, (2) the spatial distribution of the inundation depths based on the 304 points of measured data was clarified and (3) statistical analysis of building damage and inundation depth data in the Kasugano and Ukai areas revealed that the damage probability reached 10 % as the inundation depth was 170 cm, and increased to 80 % as the inundation depth reached 258 cm.</p>
