Tsunami Deposit Preservation Outcrop, Noda Village, Iwate Prefecture

South of Tofugaura Park, Noda Village, Iwate Prefecture. Outcrops along the coast near Route 45 (cars can be seen). Exposed outcrop is from the Cretaceous. The grassy outcrop in front of the prefabricated hut at the right side of the exposed outcrop shows layers of tsunami deposits dating back about 6500 years. This valley topography has miraculously preserved tsunami deposits for many years without river inflows from the landward side (Onodera, 2023). Shells from the tsunami caused by the 2011 Off the Pacific Coast of Tohoku Earthquake can be seen at the top of the exposed outcrops. The maximum run-up height in this area is about 40 meters. The image was taken by a drone from the sea (July 2021).
