After the 2024 Noto peninsula earthquake, we investigated the damage of tombstones at 350 sites in the wide area of Noto region and the western Toyama Prefecture. The overturning rate of tombstones was significantly high in Wajima, Suzu, Noto, Anamizu, Shika and Nanao. The rate generally decreases with the fault distance. Correlation between the overturning rate and the surface geology was relatively high. We established the fragility curve of the tombstone from the comparison between the overturning rate and the ground motion records and we then estimated the ground motion intensity during the 2024 Noto peninsula earthquake.
