From: Numerical estimation of a tsunami source at the flexural area of Kuril and Japan Trenches in the fifteenth to seventeenth century based on paleotsunami deposit distributions in northern Japan

Computation results using the S2 model with an 18 m slip. Comparison computed inundation area with tsunami deposit distributions reported by previous studies: a Sekinehama (Ishimura et al. 2022), b Odanosawa (Tanigawa et al. 2014), c Yufutsu–Atsuma–Mukawa (Takashimizu et al. 2007), d Kabari (Takashimizu et al. 2017), e Shiraoi (Nakanishi et al. 2014), f Kojohama (Nakanishi and Okamura 2019). The red circles and rectangle show their locations. The solid contour shows the topography, and the dotted contour shows the bathymetry (less than 0 m). The topographic contour intervals are 1 m in (c), 2 m in (a), (b), and (d), and 10 m in (e) and (f). The bathymetric contour intervals are 2 m in (a), (b), and (d) and 10 m in (c), (e), and (f). The red line (right) and square (left) in e show the tsunami deposit distribution limits in transects S and I, respectively, found by Nakanishi et al. (2014). The red circle in f represents the most inland “sand layer” site in “Line KJH” investigated by Nakanishi and Okamura (2019)
