In order to clarify the actual damage caused by the 2024 Noto Peninsula earthquake, we surveyed the damage and the height of tsunami traces in the coastal area of Noto Island, Ishikawa Prefecture. The survey revealed that in the northern part of the area inundated by the tsunami, tsunami traces with a flood height of approximately 2 m were observed at the Hachigasaki Beach. On the other hand, we obtained testimony that Enome Fishing Port was inundated about 0.2 m through interviews. Although the two sites are located only about 1 km apart in the northeastern part of Noto Island, there were differences in the inundation conditions. Therefore, we conducted a tsunami reconstruction analysis to clarify the differences in the inundation process. The Hachigasaki Beach is open to the direction of tsunami incidence, whereas the Enome Fishing Port is surrounded by breakwaters and has a narrow harbor entrance.
