We conducted a field survey in the coastal areas of Wajima City and Shika Town, Ishikawa Prefecture, located in the western part of the Noto Peninsula, to investigate the effects of the tsunami and ground uplift caused by the 2024 Noto Peninsula Earthquake. The maximum height of the tsunami trace was 4.2 m in the Akasaki district of Shika Town. The inundation area and tsunami damage were localized and mainly limited to the port area or just behind the seawall. The uplift of the ground was most pronounced north of the Saikaifuto district in Shika Town, and the ground rose 3.5 to 4 m at the Kaiso and Kuroshima fishing ports in Wajima City, significantly reducing the water depth in the ports and drying up the sea floor in some areas. On the sandy beach on the south side of the Kaiso fishing port, the shoreline advanced 150 to 250 m, exposing a bar zone that was below the water surface before the earthquake, and the beach width increased significantly. It was estimated from the aerial photographs that the sandy beach expanded over about 250,000 m2 due to the uplift of the ground.
